Running jobs

Batch system: Torque

Resources manager: Moab

For purpose of running jobs the knowledge of basic commands of batch system is required.

For vSMP machines a separate queues server is running. Access to a queue for vSMP machines is possible only after loading proper module first (see Modules section):

module add vsmp/torque-client

Since the commands handling this queues server are not compatible with the rest of the cluster commands, there are corresponding aliases created (by adding 'v' suffix) as described in the table below. Features and parameters of commands are both the same as for the rest of the Zeus cluster.

Name of vSMP command	Its equivalent on the remaining part of Zeus
vqstat	qstat
vqsub	qsub
vqdel	qdel
vpbsnodes	pbsnodes

Queues description

Queue name	Maximum jobs number per user	Maximum job duration	Additional information
vsmp	8	no limit

Description of compute nodes properties

Property	Description
mhz2666	processor speed
mem320gb, mem630gb, mem1200gb	amount of RAM on vSMP machine

Rules on the Zeus cluster

• Performing computations on accessing server is strictly prohibited. Administrators will terminate that jobs without warning.

• For compiling a program use following command: vqsub -I -q gpgpu -l nodes=1:ppn=1:gpus=1
  This command logs user on compute node, where compilation should be done.

• In order to compute, it is necessary to specify grant identifier using "-A" parameter.
