Computational Cluster Programs

Computing on the Cardio Cluster

The preferred way to access the Cardio Cluster is through the UCLA Grid Portal at http://grid.ucla.edu. The grid portal makes the Cardio Cluster accessible from any web browser. You can submit batch jobs, run interactive GUI applications and get an xterm from the UCLA Grid Portal. If you are going to use the Cardio Cluster from the UCLA Grid Portal, to use batch or interactive services (except for xterm) you will not need to know the information presented here.

Role of the Login Node

Use the Cardio login node for logging into the Cardio Cluster.

You may do the following when logged onto a Cardio Cluster login node:

File management
Editing
Compile programs (from source code)
Test parallel jobs. Run interactive applications. However note that, any program that requires more than 1 hour to complete and which does not require considerable human interaction must be submitted to a batch job queue.

Batch Jobs

Most of the nodes on the Cardio Cluster are dedicated to running batch jobs. All non-interactive programs that require more than 1 hour to complete must be submitted as batch jobs.

The Cardio Cluster has 32 compute nodes named n01, n02, ... n32. You can run at most a 128 processor job as each node has 4 cores.
