Hints for usage

  • granularity should be a socket (28 cores)
  • can be used for OpenMP applications with large memory demands
  • OpenMPI does not work properly here. For MPI applications: use IntelMPI !
  • Use I_MPI_FABRICS=shm so that Intel MPI doesn't even consider using InfiniBand devices itself, but only shared-memory instead

Open for Testing
