Creating and tweaking Slurm queues for your clusters
Compute queues are where all the action is on an HPC cluster. In the cloud, you get the chance to customize the queues to match the code you’re going to run on them - which is actually pretty fancy when you think about it.
Matt Vaughn stopped by to show us how to do all that in a few clicks. ParallelCluster is quite powerful and VERY configurable. Thankfully, it’s UI makes this all a good deal simpler than it sounds.
