Hoffman2:Introduction
What is Hoffman2?
The Hoffman2 Cluster is named for Paul Hoffman (1947-2003) and is a campus computing resource at UCLA. It is maintained by the Academic Technology Services Department at UCLA and they host a webpage about it here [1]. More than one thousand UCLA members have accounts on this cluster.
Anatomy of a Computing Cluster
Login Nodes
There are four login nodes which allow you to access and interact with Hoffman2. These are essentially four dedicated computers that you can SSH into, use to look at your files, and use to submit computing jobs to the queue (more on that in a bit). It is important to remember that these are four computers being shared by ALL the Hoffman2 users so doing ANY type of computing on these is frowned upon. If you are moving a bunch of files, calculating the inverse solution to an EEG signal, or running a bunch of python iterations, you should not be doing this on a login node.
Computing Nodes
There are more than 800 computing nodes, each with 8, 12, or 16 cores and 1GB, 4GB, or 8GB of RAM per core
