Queuing System

Obsidian uses TORQUE Resource Manager to control batch jobs and distributed computing resources. All jobs should be submitted via TORQUE. Please be courteous to other users and do not run computational tasks on the head node. Any process running on the head nodes which adversely impacts system operation is subject to preemptory termination

Use Infiniband and IPoIB

Interactive Job

If you need to run jobs interactively, use qsub to request interactive job. For example:

qsub -I -l nodes=2:ppn=20,walltime=00:30:00
qsub: waiting for job 179.obsidian.cluster to start
qsub: job 179.obsidian.cluster ready
