Availability of MPI-2 routines

Implemented features in HP-MPI 1.5:

• Onesided Communication
  • basic communication and synchronisation
  • only on a single host
• MPI-I/O
  • most things implemented
  • shared file pointer (MPI_File_write_shared etc.) implemented (but undocumented)
• Language Interoperability
• Thread Compliant Library
  • only for MPI-1 routines
• Miscellaneous Features
  • MPI_Alloc_mem, MPI_Info
  • MPI_Type_create_subarray
    • additional type constructor for MPI-I/O
    • undocumented

Missing features:

• Process Creation and Management
  • ok, not so important on parallel computers
  • but: useful for coupling of large applications, debugging or visualization
• Extended Collective Operations
  • helpful for process management
• Datatype Manipulation Functions
  • important for MPI-I/O and 64bit addresses
• Language Bindings for C++
  • well, we can use the C bindings ...
• Language Bindings for Fortran
  • we need it (MPI module, KIND types)!
