WEBVTT 1 00:00:05.320 --> 00:00:07.310 Doug Roberts: Welcome everyone 2 00:00:08.770 --> 00:00:19.560 Doug Roberts: where I'm holding this presentation. because we've been doing so at various shark net institutions to welcome new potential researchers. 3 00:00:20.210 --> 00:00:22.740 Doug Roberts: to 4 00:00:25.360 --> 00:00:31.730 Doug Roberts: to our consortium of institutions that provide these supercomputing resources for everyone. 5 00:00:32.150 --> 00:00:39.660 Doug Roberts: So our intention here is to raise awareness of the facilities that are available to you 6 00:00:39.840 --> 00:00:46.709 Doug Roberts: as a Laurier researcher as they are for other universities through throughout Ontario. 7 00:00:47.030 --> 00:00:48.939 Doug Roberts: So we've got a 8 00:00:49.220 --> 00:01:05.290 Doug Roberts: I'm giving this as a high level overview of all the resources and capabilities that you have access to. So let's just get going on the first slide here. So we're accessing topic is accessing super computers, clouds, storage. 9 00:01:05.560 --> 00:01:12.099 Doug Roberts: support, and training courses. So all these things go together. 10 00:01:12.260 --> 00:01:14.870 Doug Roberts: Sort of as a unit to 11 00:01:14.960 --> 00:01:21.609 Doug Roberts: to provide you this the ability to carry out advanced research computing related research. 12 00:01:21.820 --> 00:01:29.959 Doug Roberts: So it's a bit of a it's a wide scope of things that need to be looked at in this presentation so that you have a good perspective on 13 00:01:31.090 --> 00:01:32.450 Doug Roberts: what's available to you. 14 00:01:34.890 --> 00:01:38.000 Doug Roberts: So probably wondering, 15 00:01:39.640 --> 00:01:47.330 Doug Roberts: firstly, why do you need super computers? And once you've determined this, what's available to you 16 00:01:48.060 --> 00:01:51.050 Doug Roberts: and how to access them. 17 00:01:51.110 --> 00:01:55.550 Doug Roberts: Manage your files. run programs. 18 00:01:56.940 --> 00:02:05.380 Doug Roberts: basically things that might initially plan on doing on your desktop. But pretty quickly. You'll realize 19 00:02:05.960 --> 00:02:10.460 Doug Roberts: that the CPU power, the storage 20 00:02:10.770 --> 00:02:14.750 Doug Roberts: that you have on your desktop is not capable 21 00:02:14.860 --> 00:02:20.449 Doug Roberts: of doing the tasks that need to be done to carry out research 22 00:02:20.720 --> 00:02:25.349 Doug Roberts: competitive research with against other researchers 23 00:02:25.630 --> 00:02:28.489 Doug Roberts: and fulfill requirements of your program. 24 00:02:28.880 --> 00:02:30.920 Doug Roberts: very well. 25 00:02:30.940 --> 00:02:35.209 Doug Roberts: So this is why you need to turn to a supercomputing facility 26 00:02:35.350 --> 00:02:37.919 Doug Roberts: to conduct your research. 27 00:02:40.860 --> 00:02:44.989 Doug Roberts: And I'm gonna try to describe how to do that 28 00:02:46.320 --> 00:02:48.510 Doug Roberts: along with what's available. 29 00:02:52.660 --> 00:02:57.619 Doug Roberts: So put in bullet form. Why you need these resources. 30 00:02:57.680 --> 00:03:03.790 Doug Roberts: As I mentioned, your desktop won't have enough cores or memory, most likely. 31 00:03:04.850 --> 00:03:13.110 Doug Roberts: or a Gpu which is needed. A professional gpu that's capable of running for like a long period of time. 32 00:03:13.250 --> 00:03:22.419 Doug Roberts: without causing any problems to the system itself. You probably need a lot of disk space 33 00:03:22.920 --> 00:03:32.010 Doug Roberts: which the supercomputing facilities that we have provide. and these can vary from a small amount of disk space to a very large amount. 34 00:03:32.140 --> 00:03:35.279 Doug Roberts: None of these things are like 35 00:03:35.950 --> 00:03:46.020 Doug Roberts: mandatory requirements to use the facilities. So if you don't need much memory, or cores, or Gpus, or disbelace, or you just need one of them. 36 00:03:46.380 --> 00:03:51.320 Doug Roberts: Then that's perfectly fine. You don't have to feel well. 37 00:03:51.550 --> 00:04:05.580 Doug Roberts: I don't. I don't have all these exact needs, therefore I really don't need to go there, or they won't want me there. Something like that. Not everybody needs everything. Some people do, but not everyone does. So 38 00:04:06.350 --> 00:04:07.939 Doug Roberts: I wouldn't be worried about that 39 00:04:09.360 --> 00:04:17.589 Doug Roberts: more mature simulations or some types of simulations might have very high demand. So you'll need a lot of cores. 40 00:04:17.630 --> 00:04:21.799 Doug Roberts: You might need to run a lot of simulations simultaneously. So 41 00:04:22.370 --> 00:04:35.419 Doug Roberts: imagine you're running your program with an input file to evaluate a case. Well, you want to do 10 cases or a hundred or thousands. Some people do millions tasks at the same time on the systems. 42 00:04:35.600 --> 00:04:46.640 Doug Roberts: So you could be any belonging to any part of that spectrum. You just wanna run a single job for a very long time. That's fine. Or you could wanna run 43 00:04:46.900 --> 00:04:51.500 Doug Roberts: lot of jobs for a long time or a lot of jobs for a short time. 44 00:04:51.590 --> 00:05:01.649 Doug Roberts: These are all sort of things you might want to do. There's web services available. There's SQL. Databases. If you need to run one. You can do that. 45 00:05:01.670 --> 00:05:07.380 Doug Roberts: There's cloud facilities. We'll get a bit more into that. And, most importantly, everything here 46 00:05:07.520 --> 00:05:12.160 Doug Roberts: on this menu is free. 47 00:05:13.260 --> 00:05:24.799 Doug Roberts: So you don't have to worry about money, which is something that from the inception of Sharknet. And now Sharknet is part of a larger group which I'll go to in this next slide. 48 00:05:26.040 --> 00:05:39.809 Doug Roberts: Canada wide. These facilities that I'm talking about are distributed across Canada. So we're in Ontario. So right middle there, you've got compute, Ontario. 49 00:05:39.940 --> 00:05:48.270 Doug Roberts: We have a couple of systems that are part of Sharknet. You can see the sharknet logo that's in sort of the lower part of Ontario. 50 00:05:48.370 --> 00:06:02.810 Doug Roberts: That's what Laurier belongs to other institutions in Ontario, like Western and Windsor. Hamilton. These places all belong to Sharknet, so were all sort of a community 51 00:06:03.030 --> 00:06:06.110 Doug Roberts: known as sort of a consortium 52 00:06:06.400 --> 00:06:07.830 Doug Roberts: called sharkness. 53 00:06:07.920 --> 00:06:22.480 Doug Roberts: There's also another one Ontario, a bit of an outlier called cynet, which is specific for U of T researchers. So they have their sort of own consortium. But UT. Is quite a bit larger upon itself. So 54 00:06:23.060 --> 00:06:30.129 Doug Roberts: this is how things have evolved all the other Ontario universities comprise sharp net, and then you've got 55 00:06:30.560 --> 00:06:34.049 Doug Roberts: another one in Ontario. 56 00:06:34.060 --> 00:06:40.879 Doug Roberts: called sign it. So outside we've got in Quebec. Very strong group support groups in Quebec. 57 00:06:40.940 --> 00:06:47.769 Doug Roberts: It's known that consortium Universities there is known as Calcule Quebec. Keep going east. You've got a snack and west. 58 00:06:47.790 --> 00:06:54.330 Doug Roberts: Go all the way out to BC. You've got cedar cluster. These are the cluster names I am talking about now. Cedar 59 00:06:54.450 --> 00:06:56.410 Doug Roberts: Is within 60 00:06:57.170 --> 00:06:58.650 Doug Roberts: the western part 61 00:06:59.140 --> 00:07:07.690 Doug Roberts: out east in Quebec. You've got clusters sort of showing their Narvall and Beluga in Ontario. We've got Graham and Niagara. All this will get 62 00:07:08.070 --> 00:07:18.250 Doug Roberts: you'll get more comfortable with this. When you know the names of the the compute systems themselves have names just like we do. So you become sort of familiar with it by their name. 63 00:07:19.680 --> 00:07:37.079 Doug Roberts: and you can access anything across Canada cause they're all different. Whatever suits your needs. You go to the place that best matches your needs. I think if you read the abstract that I sent out, I put a little sense in there about that. So we've got 64 00:07:37.590 --> 00:07:47.769 Doug Roberts: a little animation here to show of the inside of a server room in case you're wondering what they look at. Look like. Oh, okay, it's running on the other screen. I'm sorry about that 65 00:07:47.840 --> 00:07:49.649 probably cannot see it. 66 00:07:50.210 --> 00:07:53.080 Doug Roberts: So anyway, we got 2 shots here. 67 00:07:53.150 --> 00:07:57.180 Doug Roberts: These are the back of servers just showing the cables that connect them. 68 00:07:57.490 --> 00:08:02.780 Doug Roberts: essentially, that what that's what you have 69 00:08:03.530 --> 00:08:05.859 Doug Roberts: in the server room 70 00:08:06.800 --> 00:08:22.840 Doug Roberts: is servers that are stacked into racks, and the racks are all connected into aisles, and these things generate a lot of heat, and they're locked away in safe places because it's highly secure. And it's highly intensive to keep these things cool in a proper environment that alone involves 71 00:08:22.910 --> 00:08:25.800 Doug Roberts: lot of people at the universities that 72 00:08:26.130 --> 00:08:43.970 Doug Roberts: allow these clusters to be located there. So originally, Sharknet, we had clusters. When Sharknet was born. It was born at Western, very strong support there, and clusters, a server room evolved with clusters. And then there's some clusters across campus. 73 00:08:44.030 --> 00:08:53.040 Doug Roberts: This spread to Hamilton. They had a cluster there. Now the primary cluster is in Waterloo, called Graham, as I mentioned. 74 00:08:53.110 --> 00:08:58.950 Doug Roberts: and so you can just imagine that this room is very loud. 75 00:08:59.040 --> 00:09:03.409 Doug Roberts: It can be very hot, depending which aisle you're in or cool. 76 00:09:03.490 --> 00:09:04.810 Doug Roberts: And 77 00:09:04.890 --> 00:09:07.589 this is where all the compute action occurs. 78 00:09:11.130 --> 00:09:25.410 Doug Roberts: So here's a diagram that shows sort of how things interoperate. If you could say you've got the clusters, which are primary sort of workforce as a computing. That's what you log into and 79 00:09:25.500 --> 00:09:32.860 Doug Roberts: submit jobs. Each cluster has, like thousands and thousands of servers and tens of thousands of cores and 80 00:09:32.960 --> 00:09:36.530 Doug Roberts: countless amount of memory. When you add it all up. 81 00:09:36.850 --> 00:09:42.449 Doug Roberts: and either clusters have storage attached to them, which is the green circle. 82 00:09:42.500 --> 00:09:52.510 Doug Roberts: Then you've got cloud, which is something else. These are smaller systems, but they also have storage. This is why it's overlapping, and 83 00:09:53.240 --> 00:09:58.410 Doug Roberts: the clouds can can in theory work with clusters and 84 00:09:58.440 --> 00:10:12.949 Doug Roberts: everything sort of can be working together so you could be in one or the other or overlapping all of them. For sure. You're probably gonna be in the storage screen one so that's the layout. 3 primary components to think about. 85 00:10:15.030 --> 00:10:26.879 Doug Roberts: So how do you get started? And this was mentioned in the abstract. So basically, you need to go sign up. And you do that at this website. We call it Ccdb 86 00:10:27.130 --> 00:10:40.870 Doug Roberts: sort of the short form, and you can get it that from that Earl. your supervisor, firstly needs to get an account. He gets a username, and then you go to him and you can get his 87 00:10:41.040 --> 00:10:44.130 Doug Roberts: something called a ccri. 88 00:10:44.270 --> 00:10:50.500 Doug Roberts: which when you apply for account, you have to put in basically his identifier, which is that. 89 00:10:50.560 --> 00:11:01.579 Doug Roberts: And then you hit, submit, and it's approved through process. And then you can simply you'll get a username and you can log in that it. It's just as easy as that. 90 00:11:02.070 --> 00:11:16.129 Doug Roberts: So you can really get started today. You could even be doing while I'm talking it, probably. If your supervisor has an account already, that's that can be. Most of them do by now, but there could be pi, so faculty and attendance to this meeting. 91 00:11:16.150 --> 00:11:20.330 Doug Roberts: and if they're interested in using, certainly they want to 92 00:11:20.430 --> 00:11:27.000 Doug Roberts: go get an account, so their students can then get accounts. That's what I'm trying to say. 93 00:11:30.950 --> 00:11:40.720 Doug Roberts: Alright. So I mentioned, there's some clusters across the country here they are, and they've all got names. So to get familiar with. Graham's at Waterloo. Oh, my apologies. 94 00:11:41.220 --> 00:11:42.270 Doug Roberts: that's a problem 95 00:11:43.360 --> 00:11:45.590 Doug Roberts: I can't mute that 96 00:11:46.070 --> 00:11:51.869 Doug Roberts: Sorry. Just 97 00:11:52.120 --> 00:11:54.779 Doug Roberts: let's just Paul, can you mute me? 98 00:11:55.640 --> 00:11:59.849 Paul Preney: You have to mute yourself. Okay, whatever I'll figure it out. 99 00:11:59.990 --> 00:12:01.569 Doug Roberts: Thank you 100 00:12:22.880 --> 00:12:26.729 Doug Roberts: alright. Thank you. There's nothing. 101 00:12:27.130 --> 00:12:31.210 Doug Roberts: So yes, Graham is at Waterloo, which is just down the street from Laurier. 102 00:12:31.230 --> 00:12:42.579 Doug Roberts: They give tours once in a while. You could probably go over and see it. So here's a number after there 41,500 C. What is that? That's the number, of course. How many course does your laptop have? 103 00:12:42.950 --> 00:12:50.109 Doug Roberts: Probably 4, something like that nowadays previously you only had one, but nowadays probably 4 at least. 104 00:12:50.290 --> 00:13:11.889 Doug Roberts: But this thing has 41,000. Look at the other clusters. 94,000. 80,030. You get the idea. There's a lot of compute capacity more enough there to satisfy everybody's needs. That's and we're looking at. Then this is an older version of Gram relative to the other systems. 105 00:13:12.030 --> 00:13:27.769 Doug Roberts: We'll be getting a newer gram pretty soon at Waterloo, and there'll be more to add to the collective. But it doesn't really matter where these resources are located. Because you can go, you you use which everyone you need to. You just connect into it and use it. But 106 00:13:27.930 --> 00:13:37.640 Doug Roberts: yeah, we do sort of value Graham, a little bit more, cause we're at shark net. And that's our focus. We have a lot of Sys Admins within Sharknet, who's primary 107 00:13:37.820 --> 00:13:41.059 Doug Roberts: job is to ensure that Graham runs smoothly 108 00:13:41.070 --> 00:13:48.350 Doug Roberts: and meets the needs of everyone from around the country that connects into shark net. To use the sharknet systems. 109 00:13:48.540 --> 00:14:04.330 Doug Roberts: we also handle like problem, the ticket. But ticket questions that come in for Graham, the staff of Sharknet, the other consortiums are like that as well. They have IT. Staff that support their clusters in their provinces. 110 00:14:04.670 --> 00:14:15.090 Doug Roberts: and also support staff. Anyway, that's too much on the clusters. We've the clouds likewise have some names. 111 00:14:15.580 --> 00:14:26.480 Doug Roberts: some are in common, others are not. This arbitris is a different name. It's not common cluster, and you've got east. So name but 2 names of the clouds do overlap with 112 00:14:26.670 --> 00:14:33.970 Doug Roberts: cluster names coincidentally. There's different types of gpus that are on the clusters 113 00:14:34.110 --> 00:14:42.299 Doug Roberts: lot. More researchers are now using incorporating Gpus to speed up their codes 114 00:14:42.350 --> 00:14:49.879 Doug Roberts: and investigating how to do that. That's a little bit next level in your ability at programming and 115 00:14:50.340 --> 00:14:54.160 Doug Roberts: sort of things like this. It's just a bit more complex. 116 00:14:54.920 --> 00:15:19.929 Doug Roberts: but may be well worth your while to look into Gpu use if you're looking at research, and you discover that some of the research is being done with Gpus. Well, we have Gpus that are state of the art to here, and certainly you could go down that path with your research utilizing this sort of resource in addition to the cpus on the clusters. 117 00:15:20.210 --> 00:15:25.480 Doug Roberts: And then there's some storage. As I mentioned. we got the 118 00:15:26.860 --> 00:15:33.919 Doug Roberts: different file systems. My goal here is not to go into too much detail. Break things down. 119 00:15:34.150 --> 00:15:38.740 Doug Roberts: Just say there's different types of disk storage 120 00:15:38.970 --> 00:15:43.629 Doug Roberts: where you put your files that some of them perform differently. 121 00:15:43.660 --> 00:15:51.190 Doug Roberts: Fast and slow. Weathers have a lot more space. Others are designed to keep your data for a very long time. 122 00:15:51.450 --> 00:15:57.090 Doug Roberts: while others it'll just be gone 60 days. 123 00:15:57.280 --> 00:15:58.859 You don't do anything 124 00:15:59.110 --> 00:16:03.789 Doug Roberts: we have tape back up. You've probably heard of that. Tapes still do exist. 125 00:16:03.870 --> 00:16:05.020 And 126 00:16:05.190 --> 00:16:12.089 Doug Roberts: yeah, they're an important part of the infrastructure here. If something happens, you can get your data back on tape 127 00:16:12.390 --> 00:16:19.850 Doug Roberts: pretty reliably. So that's something real peace of mind. Some. It's a real concern, you know. What could happen 128 00:16:20.050 --> 00:16:24.289 Doug Roberts: to your data. What would you do if you lost everything? Well. 129 00:16:24.410 --> 00:16:29.170 Doug Roberts: we're take a lot of they very seriously to support that. That doesn't happen. 130 00:16:36.020 --> 00:16:44.460 Doug Roberts: Okay, so a little bit about the servers, the operating system that runs on a mix Linux base. It's not windows. 131 00:16:45.020 --> 00:16:49.910 Doug Roberts: So that may not may or may not mean much to you, but 132 00:16:50.170 --> 00:17:06.110 Doug Roberts: it really does. It impacts how we use the systems. So you're probably used to on windows sort of the point and click kind of thing on the super computers. You're more or less typing in commands on the command line and kind of it's like learning a new language. 133 00:17:06.810 --> 00:17:10.789 You've got languages, as far as computing goes. 134 00:17:10.950 --> 00:17:18.530 Doug Roberts: Probably heard of Fortran. See, they're all there. Python is very popular. Everybody's using python nowadays 135 00:17:18.700 --> 00:17:22.549 Doug Roberts: seem like back in the beginning. Everybody was trying to use. 136 00:17:22.800 --> 00:17:28.459 Doug Roberts: you know, see? Or Fortran to make their codes run fast. Now it seems more about 137 00:17:28.520 --> 00:17:35.170 Doug Roberts: flexibility and number of free programs around that you can use and build into your 138 00:17:35.300 --> 00:17:39.030 Doug Roberts: solving your problem. So Python is there for that. 139 00:17:39.490 --> 00:17:42.260 Doug Roberts: And commercial 140 00:17:42.510 --> 00:17:46.040 Doug Roberts: software like Matlab 141 00:17:46.800 --> 00:17:48.789 Doug Roberts: to have a might. 142 00:17:48.800 --> 00:17:57.350 Doug Roberts: There's other things that are open source like Julia, and to help you use the Gpus languages like Kuda. Maybe too much detail. 143 00:17:57.530 --> 00:18:02.729 Doug Roberts: If you wanna be using all these cores to speed up your code, then you need to 144 00:18:02.830 --> 00:18:06.250 Doug Roberts: deal with porting it to be parallel. 145 00:18:06.490 --> 00:18:20.869 Doug Roberts: So you might use something like Mpi to distribute program over many servers. Open Mpa. Distributed within a server over the course in parallel that can be really efficient. 146 00:18:21.770 --> 00:18:25.130 Doug Roberts: Other things to speed it up 147 00:18:25.370 --> 00:18:27.350 Doug Roberts: cuda, and 148 00:18:28.400 --> 00:18:46.770 Doug Roberts: everything else is porting parallel. So really depends what you wanna do. You're gonna need support yourself to probably do this. This is where the experts come in that are available within shark net and across the country to answer your questions, how to do this. And first step is a new user. 149 00:18:47.180 --> 00:18:52.430 Doug Roberts: Deciding what you're gonna do is probably the most important thing you'll ever do. 150 00:18:52.460 --> 00:18:54.449 Doug Roberts: As in your 151 00:18:54.750 --> 00:19:12.169 Doug Roberts: HPC. Career, because if you go off in the wrong direction. It can be very time consuming to restart everything. When you realize. Oh, I should have done it this way. I'll never solve the problem this other way. I gotta go back and do it this way. It could cost you. 152 00:19:12.460 --> 00:19:16.150 Doug Roberts: you know, a year easily of hard work 153 00:19:16.380 --> 00:19:25.330 Doug Roberts: to restart something like that. So in the beginning take the time to look at all the options, familiarize, familiarize yourself if you decide to use the systems 154 00:19:26.500 --> 00:19:30.690 and all sorts applications at the bottom there mentioned again. Python. 155 00:19:31.070 --> 00:19:32.880 Doug Roberts: Julia, things 156 00:19:36.100 --> 00:19:38.930 Doug Roberts: alright. So how do you connect to the systems? 157 00:19:39.290 --> 00:19:52.150 Doug Roberts: Zoom, you've decided you you're gonna use Sharknet or the Alliance. All these systems we use secure protocol to connect so it can be like a command line tool on a Linux system 158 00:19:52.270 --> 00:19:55.590 Doug Roberts: or a client on your windows system. 159 00:19:56.430 --> 00:20:03.700 Doug Roberts: You just sort of download and click it and then specify the name of the 160 00:20:04.150 --> 00:20:14.680 Doug Roberts: cluster that you connect to. And then you'll just basically, once you have your authentication, which was known as password setup. All that sorted out. You'll just log right in. 161 00:20:14.770 --> 00:20:21.809 Doug Roberts: And so there's just a screenshot the lower right there, showing the display. The the mob X term 162 00:20:22.010 --> 00:20:26.229 Doug Roberts: lower right corner how it might look. It's got a prompt there in yellow. 163 00:20:27.760 --> 00:20:31.090 Doug Roberts: Another way to connect is over. Vmc. 164 00:20:31.270 --> 00:20:35.670 Doug Roberts: Gives you a viewer. So you do. Top left. It's kind of like 165 00:20:35.980 --> 00:20:39.459 Doug Roberts: analogous to obey term. 166 00:20:39.680 --> 00:20:47.130 Doug Roberts: You specify the cluster here connecting to which Sharknet is something kind of unique to it. 167 00:20:47.170 --> 00:20:57.689 Doug Roberts: Which we put a lot of effort in to give users the ability to run graph programs graphically. So when you connect to this system, you get your desk, you get a desktop. So 168 00:20:57.700 --> 00:21:10.109 Doug Roberts: while you're looking at your desktop, this other window will pop up with a remote desktop on your desktop, and inside that you can run all your graphical applications. Really easy. This can be done in the cluster as well, but 169 00:21:10.180 --> 00:21:17.550 Doug Roberts: on the gray Vdi system that it's sort of. You can just leave it sitting there and work away, and there's not a 170 00:21:18.000 --> 00:21:25.629 Doug Roberts: you're you don't have to work through the schedule, or some simple, simpler aspects of it, and it gives good performance with 171 00:21:25.670 --> 00:21:28.530 Doug Roberts: Gpu rendering for 172 00:21:28.810 --> 00:21:33.980 Doug Roberts: rotations. Things might need to do some heavy graphs with. So 173 00:21:34.270 --> 00:21:40.619 Doug Roberts: that's there. It's called Vmc. Grey. Vdi is mentioned, and 174 00:21:41.020 --> 00:21:52.919 Doug Roberts: it's also really useful for setting up simulations in the native Gui environments of some really advanced softwares that are like Matlab. You want to work in the Gui, probably to work on everything right and get it set up. 175 00:21:53.310 --> 00:21:57.049 Doug Roberts: and so you can do that over a remote desktop. 176 00:21:59.000 --> 00:22:02.750 Doug Roberts: There's another way to run within a graphical 177 00:22:02.770 --> 00:22:10.389 Doug Roberts: Workspace on the clusters. This is on the clusters. Now I'm talking about and it's over something called Jupiter Hub. 178 00:22:10.490 --> 00:22:11.710 Doug Roberts: and you can. 179 00:22:11.800 --> 00:22:15.700 Doug Roberts: It's pre-configured. It's got Jupiter notebooks and 180 00:22:16.420 --> 00:22:18.000 Doug Roberts: Python 181 00:22:19.130 --> 00:22:30.319 Doug Roberts: everything is inside of this. It's another sort of an environment to work graphically on the clusters. That you can utilize if you've heard about it, or if you hear about it again, it's there. 182 00:22:32.720 --> 00:22:40.809 Doug Roberts: and then you may want to do some cloud computing. So I mention the clouds. Each of the clouds says names. We've got 4 clouds. 183 00:22:41.300 --> 00:22:46.539 Doug Roberts: I can't remember the core count. So we're showing back on that slide. 184 00:22:47.220 --> 00:22:50.039 Doug Roberts: let's just go back. 185 00:22:50.600 --> 00:22:52.249 Doug Roberts: No, we didn't show it 186 00:22:52.890 --> 00:23:02.479 Doug Roberts: so I can't tell you how many cores are in these different clouds. But there'd be a lot again. Lot of cores and you work 187 00:23:02.560 --> 00:23:13.089 Doug Roberts: within openstack. You can. You're responsible for configuring everything from the operating operating system up performing updates. And you can run web servers. 188 00:23:13.180 --> 00:23:21.929 Doug Roberts: All sorts of interesting things are just not in databases and what not. You can provide access to 189 00:23:22.100 --> 00:23:29.090 Doug Roberts: apps and things for other researchers to use. but on highly developed projects. 190 00:23:29.920 --> 00:23:32.920 Doug Roberts: what not. It's quite a bit 191 00:23:33.020 --> 00:23:35.700 Doug Roberts: difference. Sort of 192 00:23:36.790 --> 00:23:38.459 Doug Roberts: what's the word? 193 00:23:38.770 --> 00:23:47.549 Doug Roberts: Kind of a companion to the clusters. It's not the right word, but sort of thing. Let's you do different things you can do on the cluster. When you think about it. 194 00:23:48.500 --> 00:23:51.220 Doug Roberts: We can do some computing in there as well. 195 00:23:53.840 --> 00:24:01.610 Doug Roberts: All right. So to trend. You'll be needing to transfer data back and forth to the systems or between systems. So you can just 196 00:24:01.950 --> 00:24:04.860 Doug Roberts: some again, a little bit more detail in for new user 197 00:24:04.980 --> 00:24:07.849 Doug Roberts: new users. But to help you 198 00:24:08.450 --> 00:24:09.850 Doug Roberts: to be a 199 00:24:09.910 --> 00:24:20.569 Doug Roberts: sort of aware that something called globus is available to you in future. When you start dealing with a lot of data. There is this sort of graphical tool that's gonna 200 00:24:20.990 --> 00:24:21.870 Doug Roberts: work. 201 00:24:22.310 --> 00:24:35.569 Doug Roberts: Are we efficiently sort of optimized manner to transfer the data that you've got to something called endpoints between these endpoints. It's all it's all to do. This efficiently 202 00:24:35.680 --> 00:24:40.060 Doug Roberts: does require some sort of infrastructure. It's not easy to do yourself. 203 00:24:40.150 --> 00:24:48.320 Doug Roberts: So that's why this is there as as a tool. So data transfer is something that impacts you in the future. Think about Lobos. 204 00:24:51.020 --> 00:25:04.850 Doug Roberts: II keep talking, and the information keeps piling up. And no, I've not scratched even like fraction 1% of it. So. But we do keep everything we do. There is document here readily readily available. 205 00:25:05.210 --> 00:25:12.880 Doug Roberts: These links, this link on the left, primarily now used to be on the right link, but 206 00:25:13.060 --> 00:25:17.859 Doug Roberts: as sharknets now become part of the Alliance. All the other 207 00:25:18.050 --> 00:25:27.619 Doug Roberts: people, like all the other shark nets of Canada. Everybody is putting all the documentation into this alliance link. So everything is there? It's open. You don't need a password to connect. 208 00:25:27.860 --> 00:25:36.290 Doug Roberts: and every package has documentation, every system does everything I've talked about like clobus and Vdi 209 00:25:37.400 --> 00:25:41.670 mobax term file systems, the structure. It's all here 210 00:25:41.680 --> 00:25:45.839 Doug Roberts: in docs.alliance.ca. so 211 00:25:47.020 --> 00:25:54.439 Doug Roberts: probably everything you need is there? And if something is not clear, then you can open a ticket and ask a question 212 00:25:56.320 --> 00:25:58.649 Doug Roberts: both that 213 00:25:59.380 --> 00:26:10.810 Doug Roberts: the link on the right for Sharknet is showing things like events like the new user seminar. So if you decide to get an account, then you want, first thing you're gonna want to do is attend the new user seminar and it'll go into more. 214 00:26:10.840 --> 00:26:20.459 Doug Roberts: a lot more targeted topics than sort of this rambling talk. That you need to know specifics, and you can ask questions. So 215 00:26:21.460 --> 00:26:28.720 Doug Roberts: find that@sharknet.ca lower left corner in the events box. And there's some news news feed in the middle as well. 216 00:26:29.940 --> 00:26:36.369 Doug Roberts: That information is not available in the the left hand link you will connect. 217 00:26:39.200 --> 00:26:48.430 Doug Roberts: as mentioned. Here's just the events, Link, sort of. There's a calendar with that which you will find, and every 218 00:26:49.030 --> 00:26:53.160 Doug Roberts: new user seminar every Tuesday you can always go back. Revisit that 219 00:26:56.480 --> 00:27:12.120 Doug Roberts: if you want for a refresher. That's not a bad idea to do, and plus you might, because it's kept up to date. If things have changed a bit since, like, let's say you saw you go to it soon, and then 2 years from now 220 00:27:12.290 --> 00:27:16.249 Doug Roberts: go back and revisit that new user seminar to get the latest. 221 00:27:16.340 --> 00:27:20.609 Doug Roberts: The latest high points could be really valuable use of your time. 222 00:27:22.520 --> 00:27:31.020 Doug Roberts: Then there's bi-weekly seminars on different topics given by the support analyst 223 00:27:31.260 --> 00:27:40.299 Doug Roberts: the Sis, Sys Admins will talk about technical topics. Just a variety of things. If you had a topic you would want 224 00:27:40.340 --> 00:27:43.820 Doug Roberts: covered, you could submit it and ask us, and I think that could be. 225 00:27:43.910 --> 00:27:45.349 we'd be open to 226 00:27:46.560 --> 00:27:53.360 Doug Roberts: to doing topics by suggestion, I'm sure, because usually we we choose them. So force it upon you. But why not? 227 00:27:55.300 --> 00:27:56.780 Doug Roberts: I'm gonna use that. Twitter 228 00:27:57.760 --> 00:28:05.180 Doug Roberts: got Twitter and Youtube. Lots of stuff is on Youtube. for sharknet. 229 00:28:06.220 --> 00:28:13.620 Doug Roberts: And there's your link, Youtube, dot, sharp net, dot cas check that out. We've recorded almost everything. I think. 230 00:28:14.380 --> 00:28:17.469 Doug Roberts: at this point and put it up there. It's 231 00:28:18.710 --> 00:28:25.070 Doug Roberts: there's no no hesitation to record things and put it up so that it's not forgotten, and 232 00:28:25.250 --> 00:28:33.400 Doug Roberts: the effort people put into that to present that information isn't lost with a one time sort of thing. So you can go back and you watch those, as you know, Youtube. 233 00:28:35.090 --> 00:28:39.559 Doug Roberts: more on this where to get help. 234 00:28:41.300 --> 00:28:49.899 Doug Roberts: So in the Alliance link that I so I gave showed you 2 slides ago. There's a support. If you look down the left menu. 235 00:28:50.180 --> 00:28:58.660 Doug Roberts: it'll show you how to request for support. And basically you're going to send an email to support@techalliance.ca. 236 00:29:00.220 --> 00:29:06.549 Doug Roberts: you could contact. Try to reach people at the sites 237 00:29:06.610 --> 00:29:12.429 Doug Roberts: by finding the analysts. Those that are working locally. Anyway. 238 00:29:13.030 --> 00:29:25.200 Doug Roberts: yeah, you can come in and talk to us, or you want to be sure we could do it virtually. Might be user easier 239 00:29:25.800 --> 00:29:28.470 Doug Roberts: for people nowadays. 240 00:29:29.010 --> 00:29:35.730 Doug Roberts: make some sort of arrangement. Basically, contact is, if you think you need in person support. 241 00:29:35.960 --> 00:29:42.299 Doug Roberts: That's why we have a staff at each. Most of the universities within shark net 242 00:29:42.350 --> 00:29:44.950 Doug Roberts: at the Ontario Universities. 243 00:29:46.150 --> 00:29:49.939 Doug Roberts: At least 50% of them have staff locally. So 244 00:29:50.030 --> 00:29:52.569 Doug Roberts: you could. Really, you can come in and see us 245 00:29:52.970 --> 00:30:03.699 Doug Roberts: contacts. or you could contact anybody. If somebody is somebody their skills align with whatever you're doing, even if they're not at Laurier. So you want, there's a specialist at Western 246 00:30:03.950 --> 00:30:08.170 Doug Roberts: or Mcmaster. or York, or where Windsor. 247 00:30:08.590 --> 00:30:15.630 Doug Roberts: we will match you to that person. So this doesn't need to be a local person. If you want to talk to somebody. 248 00:30:16.110 --> 00:30:17.170 Doug Roberts: Okay. 249 00:30:20.020 --> 00:30:33.090 Doug Roberts: if you have projects that require more than us telling you how to fix the problem or short snippets of code, providing short snippets, saying, You know, this will fix it, or 250 00:30:33.430 --> 00:30:38.779 Doug Roberts: you could do this or that. Then you want us to do the programming. There's something 251 00:30:38.820 --> 00:30:43.020 Doug Roberts: available for dedicated program support, where an analyst 252 00:30:43.280 --> 00:30:45.809 Doug Roberts: dedicates part of 253 00:30:47.890 --> 00:30:50.799 Doug Roberts: part of his day. For a period of time 254 00:30:50.830 --> 00:31:00.969 Doug Roberts: 4 months is suggested. There could be couple of days a week that he worked specifically on your problem to help move that thing forward, maybe training. At the same time, you're learning 255 00:31:01.060 --> 00:31:03.939 Doug Roberts: how to handle it so you can then take it over 256 00:31:04.600 --> 00:31:05.850 at some point. 257 00:31:09.400 --> 00:31:14.159 Doug Roberts: So there's there's not a lot like, not everybody can do this. So 258 00:31:14.210 --> 00:31:25.060 Doug Roberts: the applications are reviewed and selected and then assigned, based on certain conditions being met and the best usage of the people that we have for those. 259 00:31:28.680 --> 00:31:30.170 Doug Roberts: Yeah. So 260 00:31:30.340 --> 00:31:31.330 Doug Roberts: there's 261 00:31:32.610 --> 00:31:44.089 Doug Roberts: never ending amount of training going on and workshops. So you can find those. As I mentioned on the sharknet site. Watch your email. 262 00:31:44.130 --> 00:31:47.270 Doug Roberts: Never like, I'm sure, can. It sends email. Don't just 263 00:31:47.460 --> 00:31:49.419 don't. Please don't put it into the Europe. 264 00:31:50.720 --> 00:31:56.240 Doug Roberts: I don't spam folder something like, read everything cause events are always happening, and you don't want to miss them. 265 00:32:01.030 --> 00:32:02.090 Doug Roberts: So 266 00:32:02.370 --> 00:32:05.329 Doug Roberts: that that really is, ends the resources section. 267 00:32:06.220 --> 00:32:11.830 Doug Roberts: Now, something to understand. How do you access? How do you? How does your pi 268 00:32:12.050 --> 00:32:16.450 Doug Roberts: get access to the resources. 269 00:32:18.200 --> 00:32:19.490 Doug Roberts: And so 270 00:32:22.810 --> 00:32:26.610 Doug Roberts: pis need to apply if they know that they're gonna 271 00:32:26.620 --> 00:32:33.340 Doug Roberts: be commencing on a large amount of calculations that need to be done in a certain amount of time. 272 00:32:34.220 --> 00:32:41.160 Doug Roberts: Then we need to know about that in detail. They submit an application called a rack. 273 00:32:41.370 --> 00:32:49.109 Doug Roberts: explaining the exact amount of storage, or cores, or servers, or computers, whatever it is that they need to get it done. 274 00:32:49.140 --> 00:33:03.220 Doug Roberts: And then these applicate these applications are processed to prove and allocated onto different systems. There's a whole process for this and the Pi's need to. 275 00:33:04.040 --> 00:33:12.510 Doug Roberts: They need to be on top of it essentially, and oversee their entire work group. so that this gets done 276 00:33:12.680 --> 00:33:25.019 Doug Roberts: in according to the application form. Everything needs to be filled in for all the the groups all the research projects that are to be undertaken, and it's all broken down 277 00:33:25.450 --> 00:33:26.870 Doug Roberts: and whatnot 278 00:33:27.930 --> 00:33:30.149 Doug Roberts: so that is called 279 00:33:30.240 --> 00:33:42.499 Doug Roberts: can see it rack. Just think, rack. And if you Google, the rack in the the Alliance, Wiki Link. or even just Google it with alliance, we'll get the Alliance website which gives a lot of information about rack. 280 00:33:48.780 --> 00:33:53.140 Doug Roberts: So or you can email us at help. And 281 00:33:53.820 --> 00:33:57.539 Doug Roberts: we've already had sessions explaining to researchers. 282 00:33:57.670 --> 00:33:59.499 Doug Roberts: So the 283 00:34:00.060 --> 00:34:05.449 Doug Roberts: the rack period is lasts for a year. So you apply in the fall 284 00:34:05.520 --> 00:34:06.950 Doug Roberts: for your rack. 285 00:34:07.240 --> 00:34:11.600 Doug Roberts: That will be for the next year, basically, that'll take place. 286 00:34:11.719 --> 00:34:26.399 Doug Roberts: So by January you'll get your award, and you can start your computing based on what you were given, since quite often the requests exceed the resources available. Some of them, ha! Unfortunately are reduced. 287 00:34:26.580 --> 00:34:31.889 Doug Roberts: so your expectations might not be 100% met, but 288 00:34:32.030 --> 00:34:40.409 Doug Roberts: just a little bit taken off from those where it can be done so shouldn't be minimal pain in that regard. 289 00:34:42.570 --> 00:34:45.700 Doug Roberts: Right? So what every graduate student should know. 290 00:34:46.280 --> 00:34:48.909 Doug Roberts: Is our next topic. 291 00:34:50.420 --> 00:34:51.170 Doug Roberts: Yeah. 292 00:34:51.500 --> 00:34:53.550 Pawel Pomorski: thanks, gentlemen, second 293 00:34:54.210 --> 00:34:58.690 Pawel Pomorski: quick quick point that the Iraq competition, the deadline is November seventh. 294 00:35:00.120 --> 00:35:07.460 Pawel Pomorski: Hello, this year. You should apply immediately. 295 00:35:08.690 --> 00:35:24.480 Doug Roberts: Yeah. So I mentioned, they've had some presentations about it already, and that's because the closing dates coming November the seventh, seventh, when you should have yours submitted so potentially, you could still some submit one now and get through it. But you're gonna have to 296 00:35:24.920 --> 00:35:32.199 Doug Roberts: work in a dedicated manner to that to get it in. And if there's questions we can be contacted.ca. 297 00:35:34.640 --> 00:35:37.470 Doug Roberts: alright. So what graduate students should know. 298 00:35:41.390 --> 00:35:43.839 Doug Roberts: or rather, what? What do they do? 299 00:35:44.340 --> 00:35:46.270 Doug Roberts: What don't they do? 300 00:35:46.720 --> 00:35:56.410 Doug Roberts: We can. Almost everything is done and computing area by everybody. And it's not just hardcore scientists. It's 301 00:35:56.460 --> 00:36:01.670 Doug Roberts: every virtually from every department within the universities. Now, as you know. 302 00:36:01.720 --> 00:36:12.389 Doug Roberts: utilizing computers, especially through a I. Things are becoming more accessible, like explosion of accessibility to advanced information. But the usual. 303 00:36:12.570 --> 00:36:15.470 Doug Roberts: Some of the common areas are there in bullet points. 304 00:36:15.630 --> 00:36:18.770 Doug Roberts: economics, finance. 305 00:36:19.220 --> 00:36:20.350 Doug Roberts: interesting 306 00:36:20.500 --> 00:36:30.069 Doug Roberts: stuff. In the scientific field mentioned middle Boat. There are couple of simulations between different solvers, sort of interesting and a bit new. 307 00:36:30.820 --> 00:36:36.390 Doug Roberts: Traditional large scale. Astro astrophysics, stuff 308 00:36:36.800 --> 00:36:39.060 Doug Roberts: weather things back here. 309 00:36:39.650 --> 00:36:44.699 Doug Roberts: A lot of this nonlinear stuff requires a large, large, large amount of computing resources. 310 00:36:44.710 --> 00:36:47.759 and there's some meshing of some domains shown. 311 00:36:50.070 --> 00:36:55.970 Doug Roberts: So I think I've covered everything. What you should know hopefully, from what I've said is now being summarized again. 312 00:36:56.620 --> 00:37:00.249 Doug Roberts: You've got thousands of computers, cores, Gpus. 313 00:37:00.390 --> 00:37:11.019 Doug Roberts: everything to help you get the work done faster if you do it properly. This important point, if you just, you know it's sort of like garbage in garbage out. If you don't take the time to do something 314 00:37:11.050 --> 00:37:35.769 Doug Roberts: properly, it could take a long time to finish. If you take a little bit of extra effort and time to use proper libraries, or better coding things like that. It could run 10 times faster, 100 times faster. So, sitting around for days. Wait for something. You could be have it done in a minute. So that's sort of the objective is to do the work faster. 315 00:37:36.160 --> 00:37:37.870 Doug Roberts: and we need to be. 316 00:37:37.880 --> 00:37:42.980 Doug Roberts: It's, you know, the the equipment can only go so far and speeding things up. It's the 317 00:37:43.000 --> 00:37:53.720 Doug Roberts: human side of it is still critically important, and that's where all the training comes in doing things, and very plan, manner per se. 318 00:37:57.040 --> 00:38:08.800 Doug Roberts: So the computers around Linux. I mentioned that not windows that could have some implications for software that you're used to using right now. So we wanna be aware of that. 319 00:38:09.910 --> 00:38:21.610 Doug Roberts: it if you want to. If there's something in windows. Essentially, there's something equivalent in Linux that's available 320 00:38:21.720 --> 00:38:36.749 Doug Roberts: that could be could be used. And we can help make those sort of. If you tell us what you're using, we can come back and say, Well, you know, because we we hear this all the time you can use this within the Linux on the systems. And it'll do basically the same thing, or hopefully, a lot better. 321 00:38:40.380 --> 00:38:48.279 Doug Roberts: Alright. So the education extremely important. You want to look at all these things mention algorithms, miracle methods 322 00:38:49.940 --> 00:39:01.190 Doug Roberts: some are mature and ready to use. And you wanna make sure that you don't repeat reinvent the wheel. because. super computing has been around a long time now, and 323 00:39:01.870 --> 00:39:08.110 Doug Roberts: almost everything's been done. And there's probably special tool. If you're thinking about doing something. 324 00:39:08.120 --> 00:39:22.479 Doug Roberts: look for that tool that's already been. It's already out there and available to you, even if it's not on the system which it probably is, we can put it on there for you that that could also mean new techniques for using these these packages. 325 00:39:24.600 --> 00:39:35.799 Doug Roberts: Basically on a Linux system. There's commands command line. And you can Google it? You can attend our training seminars, the new user one 326 00:39:36.210 --> 00:39:42.810 Doug Roberts: and get yourself comfortable with using Linux, probably in a couple of days. And 327 00:39:44.570 --> 00:39:56.929 Doug Roberts: if you're on windows you can. So you can simulate using Linux through the windows subsystem for Linux. and we've got a great course for that. We've got some great courses and 328 00:39:57.180 --> 00:40:01.620 Doug Roberts: if you attend that, you can learn exactly how to 329 00:40:01.630 --> 00:40:07.220 Doug Roberts: turn your windows machine into sort of a Linux, a Linux tool for your research. 330 00:40:07.710 --> 00:40:14.280 Doug Roberts: It's very pretty nice. okay. A lot of these things I've mentioned already. 331 00:40:14.290 --> 00:40:16.570 Highly tuned libraries is here 332 00:40:16.650 --> 00:40:21.670 Doug Roberts: down towards the bottom. Didn't mention yet, but for writing code there's 333 00:40:22.040 --> 00:40:23.060 Doug Roberts: codes 334 00:40:23.070 --> 00:40:38.259 Doug Roberts: that help debug your code. So this code or application, you run it and you tell it to run your code, and it comes back and tells you what's wrong with your code, how to speed it up or optimize it where the bugs are, and some of these are called, here's a free one. Gdb. 335 00:40:38.290 --> 00:40:42.260 Doug Roberts: there's something very expensive which we have very 336 00:40:42.480 --> 00:41:01.309 Doug Roberts: sort of. The elite in the world of debugging is Ddt. If you can get your hands on that and learn how to use that. You can, you know, run your program in real time and watch it, work through everything in your code, and you can do that in python almost any language is supported. It's all in Gui everything. So 337 00:41:01.460 --> 00:41:14.609 Doug Roberts: it'll help you get from your code which you put down into something that's working really efficiently and not stuck somewhere on some bug which can be very time consuming to find. 338 00:41:15.530 --> 00:41:18.059 Doug Roberts: That's why that tool is there? 339 00:41:20.600 --> 00:41:30.069 Doug Roberts: Alright, yes, machine learning is ported things like tensorflow and pi torch. This is all now been around for a while and very mature, and 340 00:41:30.330 --> 00:41:37.440 Doug Roberts: we have a lot of support for this stuff for people that know exactly how to implement it and stuff. So don't hesitate to ask. 341 00:41:37.670 --> 00:42:00.549 Doug Roberts: You're wondering if we do that. Yes, we totally do this, and obviously we have enough compute capacity to do it seriously. Visualization I mentioned, there's some degree Vdi machine. You can do it on the clusters. But ultimately the applications you run, and a popular one for us is called Pair View. Something else called visit. Those are both open source. You can run it at home, too. 342 00:42:00.720 --> 00:42:01.470 Doug Roberts: So 343 00:42:03.040 --> 00:42:05.040 Doug Roberts: you're not just sort of 344 00:42:06.210 --> 00:42:16.730 Doug Roberts: stuck using it on our systems. It's portable per se. Ultimately, you want all your research to be portable from what you do on our systems, that you can take it with you wherever you go. 345 00:42:16.920 --> 00:42:18.349 Doug Roberts: That's always part. 346 00:42:18.680 --> 00:42:23.869 Doug Roberts: We're we're within that ecosystem of the global Hpc community. 347 00:42:24.110 --> 00:42:28.780 Doug Roberts: And so that's sort of in mind with all the design that we have here. 348 00:42:29.950 --> 00:42:37.199 Doug Roberts: there's a link to take note of. Wanna jot it down training.sharknet.ca. 349 00:42:37.530 --> 00:42:41.029 Doug Roberts: it's probably where you're at now as a new user. So important. 350 00:42:43.540 --> 00:42:46.960 Doug Roberts: Alright! What are the training courses more on training 351 00:42:49.850 --> 00:42:55.270 Doug Roberts: all all these topics which I talked about? Everything has a training course, and even in parallel. 352 00:42:55.470 --> 00:42:59.420 Doug Roberts: So you don't have to. That's let let 353 00:42:59.430 --> 00:43:05.969 Doug Roberts: our specialists give you the information in the most efficient way, so you can learn it really, quickly 354 00:43:06.020 --> 00:43:08.420 Doug Roberts: and hopefully, properly. 355 00:43:09.520 --> 00:43:13.540 Doug Roberts: and you can work through these bullets. these initial bullets 356 00:43:15.050 --> 00:43:16.099 Doug Roberts: down in. 357 00:43:16.140 --> 00:43:20.320 Doug Roberts: then go into whichever is specific to your research near the bottom. 358 00:43:24.750 --> 00:43:34.280 Doug Roberts: So again, if you want the training courses. You need to have a supervisor. You need an alliance with an alliance account. 359 00:43:34.390 --> 00:43:43.990 Doug Roberts: so they're not open it. Then this. There's a reason for this we need to. We report all the amount of support that we deliver to 360 00:43:44.300 --> 00:43:46.689 Doug Roberts: the funding agencies, and 361 00:43:47.010 --> 00:43:57.180 Doug Roberts: therefore they're not like we can track it. If you have an alliance, count and whatnot so. and presumably a lot of what we're training you for is 362 00:43:57.490 --> 00:44:03.109 Doug Roberts: to help you use on our systems, too. So it kind of makes sense. We're not training you for 363 00:44:03.210 --> 00:44:05.709 Doug Roberts: how to write a course. 364 00:44:06.180 --> 00:44:16.769 Doug Roberts: you're looking for course assistance we still have to. You can still attend. But you've got to go through the formality of. we need to know that your alliance user, basically. So 365 00:44:18.780 --> 00:44:43.599 Doug Roberts: live classes. Now, it's becoming self driven, driven a lot of things before we used to go around the universities and present for 2 or 3 days all the courses in parallel streams. Yeah, pick and choose which one you'd want can look at others because others are running. But now it's with, you know, the remote developments and everything. It's affected us a lot. And now. 366 00:44:43.600 --> 00:45:04.090 Doug Roberts: looking at giving courses are now more available offline, so you can use it when you're at your convenience and whatnot. everything's offline. You can do all that. You don't need to be in attendance somewhere, traveling some other place. To do it so ultimately makes it easier to learn 367 00:45:04.850 --> 00:45:05.940 Doug Roberts: more convenient. 368 00:45:11.050 --> 00:45:13.740 Doug Roberts: Training courses. 369 00:45:15.740 --> 00:45:21.859 Doug Roberts: Alright. So yes, it's remote. It's over zoom, just like we're doing now, so it wouldn't be much different. And 370 00:45:24.360 --> 00:45:27.609 Doug Roberts: one option or self-paced. So basically, we've got both of them. 371 00:45:29.860 --> 00:45:32.310 Doug Roberts: Sure, I think I've I've hit the end here 372 00:45:34.460 --> 00:45:38.310 Doug Roberts: all right. So that's it. We've made it to the end hopefully a convinced 373 00:45:39.210 --> 00:45:43.389 Doug Roberts: whoever's in attendance here we got 9. Some of them are staff. 374 00:45:44.760 --> 00:45:47.649 Doug Roberts: Hopefully. Some lawyer users will 375 00:45:48.490 --> 00:45:50.329 Doug Roberts: be motivated to 376 00:45:50.370 --> 00:45:56.080 Doug Roberts: get an account on the Alliance after this. Get through, Supervisor, to get an account 377 00:45:57.040 --> 00:45:57.860 dumb. 378 00:45:58.060 --> 00:45:58.790 Doug Roberts: Yeah. 379 00:46:00.030 --> 00:46:10.940 Doug Roberts: thanks for attending. Yeah, we'll open up for questions. I'll stop the recording, and we'll open up the questions, and you can unmute yourself or ask 380 00:46:10.960 --> 00:46:13.899 Paul Preney: to ask question, or put it, put it in the chat.
