Name of accessing machine

Rules are the same name as for the rest of the Zeus cluster: Name of accessing machine

Disk resources

Rules are the same name as for the rest of the Zeus cluster: Disk resources

Available software

Description of available software is here.

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 computing 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 computing node, where compilation should be done.
  • In order to compute, it is necessary to specify grant identifier using "-A" parameter.

Detailed description of grants can be found here.
