Discovery Setup for Mac
Access to Discovery cluster from Macintosh ... discovery-NETID.terminal ... Windows.
To display graphical output from remote Linux software, you'll need Xquartz or FastX (see below), but this isn't so important with discovery since it is a batch-scheduled environment
Discovery Cluster Upgrade 2024
30th. Over the coming weeks, we'll be migrating batches of compute nodes. During this time, you may notice a decrease in available resources within the discovery7 cluster, with more resources becoming

Sample R lab (Hello world)
In this lab we will create a basic R script to print "Hello World!". Then we will use the scheduler to submit the job via sbatch.
The first step of this process is to either move your R script
Sample MPI lab (Hello World)
In this lab we will use openMPI to compile a very basic "Hello World!" script, which we will then submit to run across multiple compute nodes.
Once you have logged into the discovery cluster. The
Sample python lab (Walltime example)
In this lab we will create a simple python script, called invert_matrix.py which we will submit to the cluster. In addition we will explore what it is like for a job to run out of walltime.
