Stop-HpcTask
Cancels the specified task or subtask.
Parameter Set: id
Stop-HpcTask -JobId <Int32> -TaskId <Int32> [-Force] [-Message <String> ] [-Scheduler <String> ] [-SubTaskId <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]
Parameter Set: task
Stop-HpcTask -Task <HpcTask> [-Force] [-Message <String> ] [-Scheduler <String> ] [-Confirm] [-WhatIf] [ <CommonParameters>]
Cancels the specified task or subtask. You can specify a task or subtask by specifying an HpcTask object for the task or subtask, or by specifying the job, task, and subtask identifiers.
When you cancel a task or subtask, the job scheduler removes the task or subtask from the queue if the task or subtask is waiting to run. If the task or subtask is running, the scheduler stops the task or subtask and frees the resources that it was using so that they can be allocated to other jobs.
Only an administrator or the owner of the job that contains a task or subtask can cancel the task or subtask.
Stops the task immediately without using the grace period for task cancelation. Only tasks that respond when the user types CTRL+BREAK can use the grace period for task cancelation.

Specifies the host name or IP address of the head node for the HPC cluster to which the job that contains the task or subtask that you want to cancel was submitted. The value must be a valid computer name or IP address. If you do not specify the Scheduler parameter, this cmdlet uses the scheduler on the head node that the CCP_SCHEDULER environment variable specifies. To set this environment variable, run the following cmdlet:
Set-Content Env:CCP_SCHEDULER <head_node_name>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters
The input type is the type of the objects that you can pipe to the cmdlet.
- An HpcTask object
The output type is the type of the objects that the cmdlet emits.
- None
The built-in ConfirmImpact setting for this cmdlet is Medium. If this ConfirmImpact setting is equal to or higher than the value of the $ConfirmPreference variable for your environment, the cmdlet prompts for confirmation unless you specify –Confirm:$false. If this ConfirmImpact setting is lower than the value of the $ConfirmPreference variable for your environment, the cmdlet does not prompt for confirmation unless you specify –Confirm or –Confirm:$true.
This cmdlet was introduced in HPC Pack 2008 R2. It is not supported in previous versions.
Cancels the task with a task identifier of 2 in the job with a job identifier of 12.
PS C:\>Stop-HpcTask –JobId 12 –TaskId 2
Cancels the subtask with a subtask identifier of 12 for the task with a task identifier of 3 in the job with a job identifier of 46 without using the grace period for task cancelation, and then sets the message that explains the reason for the cancelation to "Clearing space for other tasks that need to run immediately."
PS C:\>Stop-HpcTask –JobId 46 –TaskId 3 –SubTaskId 12 –Message "Clearing space for other tasks that need to run immediately." -Force
Gets an HpcTask object for the task with a task identifier of 1 in the job with a job identifier of 25, then cancels that task by redirecting that HpcTask object to the input of the Stop-HpcTask cmdlet.
PS C:\>GetHpcTask –JobId 25 –TaskId 1 | Stop-HpcTask
