      The validation of the NUMA nodes topologies was expecting equal core indices; however, this is not always the case and should be tolerated as it doesn't affect the topology needed to generate the performance profile.To fix this we ignore comparing the indices.

    • In Progress
    • Nov 8: malformed code spotted; currently working on a reproducer internally. A workaround to unblock the business can be building the performanceprofile manually.

      Description of problem:

         This bug is filed a result of https://access.redhat.com/support/cases/#/case/03977446
ALthough both nodes topologies are equavilent, PPC reported a false negative:

  Error: targeted nodes differ: nodes host1.development.lab and host2.development.lab have different topology: the CPU corres differ: processor core #20 (2 threads), logical processors [2 66] vs processor core #20 (2 threads), logical processors [2 66]

      Version-Release number of selected component (if applicable):

          4.14

      How reproducible:

          always

      Steps to Reproduce:

          1.TBD
    2.
    3.

      Actual results:

          Error: targeted nodes differ: nodes host1.development.lab and host2.development.lab have different topology: the CPU corres differ: processor core #20 (2 threads), logical processors [2 66] vs processor core #20 (2 threads), logical processors [2 66]

      Expected results:

          topologies matches, the PPC should work fine
