Multi-node Parallelism in Julia on an HPC (XSEDE Comet)
February 23 2016 in HPC, Julia, Programming | Tags: comet, HPC, julia, multi-node, XSEDE | Author: Christopher Rackauckas
Today I am going to show you how to parallelize your Julia code over some standard HPC interfaces. First I will go through the steps of parallelizing a simple code, and then running it with single-node parallelism and multi-node parallelism. The compute resources I will be using are the XSEDE (SDSC) Comet computer (using Slurm) and UC Irvine’s HPC (using SGE) to show how to run the code in two of the main job schedulers. You can follow along with the Comet portion by applying and getting a trial allocation. READ MORE
Comparison of US HPC Resources

It can sometimes be quite daunting to get the information you need. When looking for the right HPC to run code on, there are a lot of computers in the US to choose from. I decided to start compiling a lot of the information into some tables in order to make it easier to understand the options. I am right now starting with a small subset which includes Blue Waters and some of XSEDE with rows for the parts that interest me, but if you would like for me to add to the list please let me know.
