node listcores
Displays a list of the cores that are available on the nodes in the HPC cluster.
For examples of how to use this command, see Examples.
Syntax
node listcores [/format:{list|table}] [/jobid:<jobID>]
[/scheduler:<name>] [/state:<state1>[,<state2>…]
node listcores {/? | /help}
Parameters
| Parameter | Description |
|---|---|
| /format:{list|table} | Specifies the format in which the command should display the information. The valid formats are list and table. The default format is table. |
| /jobid:<jobID> | Specifies the identifier of a job that is assigned to the cores for which you want to view information. If you specify the /jobid parameter, the node listcores command displays only the cores that are allocated to the specified job. |
| /scheduler:<name> | Specifies the host name or IP address of the head node for the cluster for which you want to display a list of cores. The value must be a valid computer name or IP address. If you do not specify the /scheduler parameter, this command uses the scheduler on the head node that the CCP_SCHEDULER environment variable specifies. |
| /state:<state1>[,<state2>…] | Specifies a list of one for more states for the cores for which you want to view information. If you specify the /state parameter, the node listcores command only lists the cores that are in the specified states. The valid states are *, all, offline, idle, jobscheduled, readyfortask, taskrunning, and taskscheduled. Specify * or all to list all cores, regardless of their state. |
| /? | Displays Help at the command prompt. |
| /help | Displays Help at the command prompt. |
Examples
To view a list of all cores in the HPC cluster, use the following command:
node listcores
To view a list of all cores in the HPC cluster that are allocated to the job with a job identifier of 122 and that have a state of taskrunning, use the following command:
node listcores /jobid:122 /state:taskrunning
