HP-MPI Version 2.0 for Windows Release Note

NOTE: Previous versions of HP-MPI Remote Launch services do not work with HP-MPI V2.0.
If you are running a service remotely using a network share for MPI_ROOT, you must uninstall
the old HP-MPI Remote Launch service and re-install the new service. If you are installing
HP-MPI locally on all nodes, this should not be an issue.
2.8 Windows HPC Scheduler API
HP-MPI V2.0 for Windows uses the new Windows HPC Scheduler API, which allows more
scheduler options such as job templates, node groups, and unit type. For a list of the new scheduler
options, see “Support for New Options” (page 12).
2.9 Collective Plugins
HP-MPI V2.0 for Windows supports collective plugins. Performance is improved by allowing
for tuned collective algorithms. HP-MPI V2.0 for Windows is packaged with plugins for AlltoAll,
AllReduce, Reduce and Xring plugins. Additional plugins will be included in future releases.
2.10 Profile Libraries
HP-MPI V2.0 for Windows supports profile libraries with the standard PMPI interface.
2.11 mpiexec Support
HP-MPI V2.0 for Windows supports mpiexec (HP-MPI exec) which translates MS-MPI flags to
the equivalent HP-MPI mpirun flags. Not all mpiexec flags are supported. For the supported
flags, see mpiexec -help. For more information, see “mpiexec Issue” (page 51)
2.12 Automatic Interconnect Selection
HP-MPI V2.0 for Windows supports automatic interconnect selection. If a valid InfiniBand
network is found, IBAL is selected automatically. It is no longer necessary to explicitly specify
-IBAL.
