Use less cores on one node? Possible? RRS feed

  • Question

  • Is there anyway I can configure the cluster to just use some of the cores on one computing node, but max on the other nodes?

    Suppose you may undersubscribe the cores on the compute node. e.g. Set-HpcNode -Name <ComputeNodeName> -SubscribedCores <N>

    Note, you need to bring the node offline before running the cmdlet.

  • You need to run 'Add-PSSnapin Microsoft.HPC' in PowerShell to load all HPC related cmdlets. Sorry for not mentioning this.

  • Thanks!

    Although, I am running HPC Pack 2016 and can't find the cmdlet at all.

    The commands is listed below.

    Any of those who will do the job..?

  • ...Or do I need to install any additional to be able to run your command? I get an error now saying it is not a recognized cmdlet.
