Dear MPI Forum Colleagues:
The Persistent WG in collaboration with the Point-to-point WG plans to read a new proposal entitled "Partitioned Communication."
A brief explanation follows since this is new to many of you as a formal proposal for MPI-4:
MPI
currently provides all multi-threaded functionality through the existing interface that was designed primarily for single-threaded operation. There are no interfaces designed specifically to address the unique requirements of multi-threaded communication in
MPI.
Partitioned
communication modes extend the behavior of persistent point-to-point communication using a non-local initialization call. Partitioned communication is "Partitioned" because it allows for multiple contributions of data to be made from potentially multiple threads/tasks
to a single communication operation.
This is the proposal formerly known as finepoints, which we've been working on for several years.
Ryan Grant will lead this reading in Chicago.
Regards,
Tony Skjellum
