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 |

| 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.
