What is the purpose of the MPI User Support Support?

User and Site related problems with MPI. This includes handling problems with job submission to sites supporting MPI. The unit will also handle general MPI on Grid related issue.

  • If an issue involves the glite-MPI packaging or mpi-start code, then the ticket should be routed to EMI MPI.
  • All other issues, such as MPI jobs failing at sites due to misconfiguration, MPI jobs being queued but not scheduled, requests for configuration guidance and MPI user application guidance etc, will be handled by MPI User Support.
  • It may also be possible that a user may encounter an issue where their MPI job fails, but is not sure/aware if this a site problem or a M/W problem (perhaps on non-backwards-compatible option is introduced into a software component), in this case I recommend that the MPI User Support Unit should be the first support unit.
  • If in doubt about the flow of an MPI ticket, please send it to the new MPI User Support unit.
  • It can then either be:
    • a) Handled immediately by the new User Support Unit,
    • b) Re-assigned to the EMI MPI Unit,
    • c) Forked, with a new ticket assigned to EMI MPI, but this is also tracked by the MPI User Support Unit.
