Description

Make MPI process binding configurable in SuperBench runner modes so benchmarks with their own topology-aware affinity logic can disable the default -bind-to numa behavior when needed.

Major Revision

  • Add a new optional bind_to field for mpi modes in the runner
  • Keep backward compatibility by defaulting bind_to to numa
  • Update MPI command generation to use the configured bind_to value instead of a hard-coded numa
