Welcome to the Research Computing cluster Shamu. Rules for using Shamu: * Do *NOT* execute directly on the Shamu login node. Grab a compute node with qlogin or script your jobs with qsub. * Do *NOT* ssh directly to a compute node to run your code. Offending users will be locked out temporarily. We are now gathering statistics to help promote Shamu in the UTSA Research Community. We are looking for the following information: * Number of presentations and papers published * Number of grants, awards or funding * Number of patents, copyrights, etc... If you have used the computational resources of Shamu for any of the above, please email your information to email@example.com. Thanks! Server Maintenance - Shamu Maintenance Friday Oct 27th From 5pm to 6pm. The system will be unavailable.The login node role is available to compile software, to submit a parallel or batch program to a job queuing system and to gather/analyze results. Other than when observing interactive jobs it should rarely be necessary for a user to log on to one of the compute nodes and in some cases compute node logins are disabled altogether.
compile your code (other than MPI code. You will need to grab a compute node and load the openmpi module and compile your code)
submit applications to the cluster for execution
monitor running jobs
