Webinar (2018-Sep-19) - Introduction to working on our HPC systems for new users.
Read WestGrid’s QuickStart Guide for Getting Started on CC National Systems.
Watch Compute Canada’s Getting Started with CC National Systems mini-webinars – a series of short video tutorials that demonstrate how to access the national clusters, submit jobs, access software, avoid common mistakes, and get help from the Compute Canada support team.

In this webinar we talk about the following command-line tools:
In the presentation, we also use a few other neat command-line tools such as hyperfine - for sophisticated benchmarking - and diff-so-fancy - which makes your diffs a lot more readable. For the Emacs users, we finish the workshop with two Emacs utilities:

Have you experienced issues with unstable SSH connections that prevent you from being productive on your favourite cluster? Do you sometimes wish you had an extra terminal open so that you could run additional programs while waiting for tasks to complete? tmux is a terminal multiplexer (installed on the clusters) that can provide solutions to both connectivity and productivity sore points. It keeps your work session alive (even under the worst network conditions) while also providing you with the power to turn your terminal into a tiled window interface. This talk walks through some of the best features that will help you get work done on the cluster.

Knowing basic Linux commands is essential for researchers using remote systems such as HPC clusters. Bash is the most commonly used Linux shell, which you will use by default on most Alliance hardware. Although we teach Bash basics in various online schools and in-person workshops many times a year, there are some useful Bash features and tricks that we never get to teach, due to our usual time constraints. Finally we can share some of them with you in this webinar!
In this presentation, we talk about running commands in a subshell, subsetting string variables, Bash arrays, modifying separators with IFS, running Python code from inside self-contained Bash functions, editing your command history, running unaliased versions of commands, handy use of bracket expansion, and a few other topics.

This webinar shows how you can easily create beautiful publications – webpages, PDFs, websites, presentations, books, etc, complete with formatted text, dynamic code and figures – with Quarto. Quarto is the successor to R Markdown. By combining the powers of Jupyter or knitr with Pandoc, it works with R, but also with Python and Julia code blocks, adding new functionality to the old tool.

Once upon a time (not that long ago), powerful text editors such as Vim and Emacs were the only nice interfaces to work with code. Nowadays, there are countless sleek and more GUI-oriented tools such as VS Code, RStudio, or JupyterLab that provide amazing IDEs, without the learning curve. So why would one still use Emacs as a programming IDE? What does that even look like? In this webinar, I show some of the many reasons why I can’t let go of Emacs, then show how it can be used as a programming IDE for Python, R, and Julia.
