The cluster consists of login nodes and compute nodes, along with a few other nodes for administration and serving files. The login nodes are shared, and at any time a login node might be in use by 10 or 20 users. For that reason, CPU- and memory-intensive jobs, as well any code that runs a risk of crashing a machine, should be run only on the compute nodes.
Compute nodes can be used both for batch jobs and for interactive jobs. See below for how to use a node interactively, and how to run GUI applications on a node.
The login nodes are named
login1, login2, login3, and login4
A description of the compute node queues can be found here.
