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
- 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)!
