HPC runs - can they pick up compute nodes with different cores RRS feed

  • Question

  • Hello Good folks,

    We are planning to use Microsoft HPC for an application. Can a run launched in HPC pick up compute nodes which have different number of cores in them? Say can a run pick up one compute node which has 2 cores in it and a compute node with 4 cores in it?

    Thanks

  • Hi, can describe your scenarios more specifically? And also help define a "run"?-- is it a MPI task? or a series of tasks?

    HPC Scheduler optimized for performance, thus the default behavior is to allocate cores on the same compute node first, and you can define the resource allocation policy such as:

    - Only resources from some node groups

    - Prefer to nodes with higher CPU numbers, or prefer to nodes with higher RAM
