The SHARCNET Summer School for Advanced Research Computing (ARC) is an annual educational event for gradute/undergraduate students, postdocs, and researchers who are engaged in compute-intensive research. These schools are free and provide beginner-to-intermediate level courses on a wide range of subjects, from traditional high performance computing to data science, machine learning, popular languages such as Python and Julia as well as domain-specific courses.

This year's summer school will run from May 25, 2021 to June 29, 2021 and will be 100% online as a single stream. Each course is between 1 and 3 days long and consists of materials on this web site and Zoom video conferencing sessions. Each class will start at 10:00am EDT and will end at 5:00pm EDT with multiple breaks.

This year all attendees are required to have a Compute Canada account before registering. Compute Canada accounts are free, but one has to be affiliated with a Canadian academic institution to qualify for one. To apply for a Compute Canada account, click this link. Be aware that it might take a couple of business days to get your account approved.

Preparing for Summer School

  • To take a full advantage of the courses, you will need a computer (PC or laptop), and reasonably good internet connection (ideally, 10 mbit/s or better).
  • You will also need a headset with (optionally) a microphone. Please test the headset before the school.
  • We will be using Zoom for both lecturing and hands on exercises. Zoom can be used from a browser, but it usually works better when installed as an app. Please create a Zoom account and test Zoom app before the summer school.

Description: This course features two sessions, focussing on first principles when interacting with the shell, and job submission through the slurm scheduler. The first day will be dedicated to the shell, and cover topics such as: starting a command-line session, moving around and looking at things, accessing software, and more. The second session will introduce the concepts necessary to understanding job scheduling in an HPC environment. By the end of both sessions, attendees will be able to connect to a Canadian supercomputer, create or upload their own scripts, and submit them to the scheduler.

Description: Writing code using modern C++ not only results in shorter, faster, and more robust code, it is also easier to maintain and update. Writing parallel code using modern C++ should result in straight-forward, sane-to-maintain/debug code. This course will cover what comprises modern C++ programming and will then present and discuss how to use modern C++ to write parallel code.

Length: 3 days

Prerequisite knowledge: Some experience writing C/C++ code.

Description: This course is in response to the inquiry from the research community: Is FORTRAN (still) supported? While to many FORTRAN sounds like Latin, with its glory in the past, an ancient, dead language today, the reality is quite the opposite. Fortran, as the way it is spelled today, is still alive, still used by many people, after undergoing significant modifications and improvement in the past two decades that are rarely seen in any other languages.

Since the introduction of the milestone of Fortran 90 standard, Fortran has become very different from its ancestor with many new modern language features. Inherited from old FORTRAN standards and enhanced by the newer ones, Fortran is still the language of choice for scientific computing for its intrinsic support for real and complex floating point operations. Its array handling, enhanced by index slicing, makes array processing similar or identical to its counterparts, such as MATLAB, hence superior to any other programming languages. The unified interface of intrinsic functions for all data types makes translating mathematical expressions to computer programmes a lot cleaner and easier. Further, since the standard 2008, the introduction of co-arrays has made writing parallel code that can run on multiple core computers and clusters trivial, one needs not to know the traditional message passing interface (MPI) library, nor threading. They are built into the syntax of the language itself.

This course is a companion to the Modern C++ course, where you will find the features missing from Fortran that are more essential to general purpose computing than number crunching. We will show some of the practice of interlanguage programming, through which the shortcomings of Fortran could be complemented by interfacing with C/C++.

Length: 3 days

Activities: In-class exercises and homework.

Description: Python has become one of the most popular programming languages in scientific computing. It is high level enough that learning it is easy, and coding with it is significantly faster than other programming languages. However, the performance of pure Python programs is often sub-optimal, and might hinder your research. In this course, we will show you some ways to identify performance bottlenecks, improve slow blocks of code, and extend Python with compiled code. You’ll learn various ways to optimise and parallelise Python programs, particularly in the context of scientific and high performance computing.

Length: 3 days

Prerequisite knowledge:

  1. Knowing what is classes and functions are.
  2. Familiarity with Jupyter Notebook and basic console use.
  3. Comfortable with the python software carpentry material.

Description: MPI is a standardized and portable message-passing interface for parallel computing clusters. The standard defines the syntax and semantics of a core of library routines useful to a wide range of scientific programs in C/C++ and Fortran. MPI's goals are high performance, scalability, and portability. It is the dominant parallel programming model used in high-performance-computing today. Through lectures interspersed with hands-on labs, the students will learn how to programming with MPI. Examples and exercises will be based on parallelization of common computing problems.

Length: 3 days

Prerequisite knowledge: Basic C/C++ and/or Fortran knowledge; experience editing and compiling code in a Linux environment.

Description: Bioinformatics is a multidisciplinary field that develops methods for turning the so-called biological big data into knowledge. Although most problems in biology are not as embarrassingly parallelizable as the physics codes that HPC systems are usually designed for, this has been starting to change in recent years. Metagenomics is an emerging field in bioinformatics that investigates microbes inhabiting oceans, soils, human body, etc. with sequencing technologies. In this two-day online hands-on session, a typical metagenomics pipeline will be explored to introduce common tools used in bioinformatics analysis and how they can be utilized in an HPC environment.

Length: 2 days

Prerequisite knowledge: Basic Unix competence and basic knowledge of bioinformatic applications are required.

Description: We begin with loading a dataset in a CSV file into R and doing some basic statistics with the dataset. We then look into how to group those R commands into an R function to avoid typing commands repeatedly when we need to redo the calculations. We move on to show how to automate the process of loading a bunch of CSV files and perform the same statistical tasks with R built-in commands and for loops. Naturally we start looking into the fundamental concepts of R programming, with focus on manipulation of lists, vectors, arrays and data frames. As an important feature and strength in statistical computing, we give a very brief introduction to the random number generators and statistical functions. We touch upon linear regression with simple, easy to understand examples. At the end of the course, we revisit the data frame that we begin with and cover more topics on data frame.

Length: 3 days
