Task 1: Minimize Tuning Time in Cluster- Specific Mode

To reduce the cluster tuning time, think about which are the most common and widely used MPI workloads on your cluster. Make a note about how they are typically run in regard to:

  • The range of hosts used
  • Numbers of ranks per host
  • Fabric used (I_MPI_FABRICS)
  • Common message sizes
  • Most popular MPI functions
