WestGrid advanced-computing workshop series: Multi-processing in Julia
This workshop is part of the Westgrid advanced computing workshop series and is one of two sessions on working with Julia. Register for Part 2 here: https://libcal.library.ubc.ca/calendar/vancouver/julia-part-2.

In a Research Commons workshop in May, we gave a quick introduction to parallel programming in Julia. For heavy computations, Julia supports multiple threads and multiprocessing, both via the Standard Library and via a number of external packages. Today we will spend more time on Julia multiprocessing with Distributed.jl, walking participants through a series of hands-on exercises where you launch processes either on the same multi-core machine or on a multi-node HPC cluster.
We expect participants to be somewhat familiar with basic Julia syntax and with running Julia codes interactively -- this material was covered in our introductory webinar https://bit.ly/2Y8LJbZ. For all participants, we will provide access (with guest accounts) to a remote cluster with Julia installed, so you don't need to install Julia on your computer (although you can via https://julialang.org/downloads). To access our remote system, you will need to install an SSH client on your computer such as the free MobaXterm Home Edition from https://mobaxterm.mobatek.net/download.html.
About the presenters:
Alex Razoumov is a training and visualization coordinator in WestGrid / Compute Canada. He has a keen interest in difficult computational problems, with a PhD in computational astrophysics from the University of British Columbia and postdoctoral experience in Urbana–Champaign, San Diego, Oak Ridge, and Halifax. He has worked on numerical models ranging from galaxy formation to core-collapse supernovae and stellar hydrodynamics, and has developed a number of computational fluid dynamics and radiative transfer codes and techniques. Alex has been with Compute Canada in one role or another since 2009. He is based in Vancouver, British Columbia.
Marie-Helene Burle Prior to entering the realm of computing, Marie-Helene Burle spent 15 years roaming the globe from the High Arctic to uninhabited Sub-Antarctic islands or desert tropical atolls, conducting bird and mammal research (she calls those her "years running after penguins"). As a PhD candidate in behavioural and evolutionary biology at Simon Fraser University, she "fell" into Emacs, R, and Linux. This turned Marie into an advocate for open source tools and improved computing literacy for all, as well as better coding practices and more reproducible workflows in science. She started to contribute to the open source community, became a Software and Data Carpentry Instructor, and worked at the SFU Research Commons providing programming support to researchers. She is thrilled to be continuing in this direction with HPC and new languages at WestGrid. When not behind a computer, Marie loves reading history books and looking for powder in the British Columbia backcountry on skis.
