The MPI Forum
Created using the HPF model
A group of 30-40 “experts” in message-passing:
- MPP vendors,
- CS researchers,
- Application developers.
Met 3 days every 6 weeks for 1.5 years and created the MPI-1 specification draft.
Communicators - communication context
needed for safe parallel library design.
Derived Datatypes - user defined datatypes for non-homogeneous, non-contiguous data.
Process Groups - collective operations can operate over a subset of the processes.
