  • hi,

    Assuming that your entire application is running on the cluster, then MPI applications with the appropriate network gear would give you the best client-server performance. A know model for MPI is the worker farm, where rank 0 sends work items to a collection of workers.

    With currently off the shelf InfiniBand or Myricom network gear, you can achieve 2usec network latency for small messages and 2GByte/sec throughput using MPI.
