“Parallel programming in Julia”
Webinar (2021-Mar-17) by Alex Razoumov and Marie-Hélène Burle
In this webinar, we start with a quick review of Julia’s multi-threading features but focus primarily on Distributed standard library and its large array of tools. We show parallelization using three problems: a slowly converging series, a Julia set, and an N-body solver. We run the examples on a multi-core laptop and an HPC cluster.

Chapel
“Intro to Parallel Programming in Chapel”
Webinar series by Alex Razoumov
In this three-part online webinar series, we introduce the main concepts of the Chapel parallel programming language. Chapel is a relatively new language for both shared- and distributed-memory programming, with easy-to-use, high-level features that make it ideal for learning parallel programming for a novice HPC user.
Unlike other high-level data-processing languages and workflows, the primary application of Chapel is numerical modelling and simulation codes, so this workshop is ideal for anyone who wants to learn how to write efficient large-scale numerical codes.
Part 1: Basic language features (2018-Feb-28)
Part 2: Task parallelism in Chapel (2018-Mar-07)
Part 3: Data parallelism in Chapel (2018-Mar-14)
“Computing graphs on an HPC cluster: working with distributed unstructured data in Chapel”
Webinar (2019-Apr-17) by Alex Razoumov
- ZIP file with slides and sample codes
“Working with data files and external C libraries in Chapel”
Webinar (2020-Mar-18) by Alex Razoumov
HPC Carpentry Course
As part of their contribution to HPC Carpentry, WestGrid staff authored a Parallel programming in Chapel course. The materials and exercises presented in this course can be presented as a full-day workshop. If you have questions about the materials, please contact Alex Razoumov - alex.razoumov@westgrid.ca.
OpenMP
Intro to Parallel Programming for Shared Memory Machines
Webinar (2019-Oct) by Ali Kerrache
This online workshop explores how to use OpenMP to improve the speed of serial jobs on multi-core machines. We review how to add OpenMP constructs to a serial program in order to run it using multiple cores. Viewers are led through a series of hands-on, interactive examples, focusing on multi-threading parallel programming.
The topics covered include:
- Basic OpenMP operations
- Loops
- Reduction variables
MATLAB
“Data Analytics and Machine Learning with MATLAB”
