Al-Salam is a 12-node cluster at Earlham College. It runs Linux (CentOS) and there are a few points about running jobs on it.

Modules

In order to manage and use different kinds of software, we use an environment management utility called Modules. This lets you run a simple command (e.g., module load openmpi) to have everything set up and managed easily.

First, you should see what kinds of modules are available for you to load:

module avail

This includes MPI implementations, different versions of Python, scientific codes, and more.

You can see which modules are currently loaded by running

module list

Queue/Batch system

Checking load

You can either run the command:

cexec "vmstat 1 3 | tail -2"
