commented Jun 14, 2018


For 64-bit clean functionality, convenience, and symmetry, the Big MPI principles being applied in Ticket #80 to collective operations should be applied to MPI RMA functionality.


64-bit clean versions of RMA operations will be provided.

Changes to the Text

New APIs and descriptions with suffix _X will be added to support 64-bit clean operations for RMA chapter.

Impact on Implementations

Implementations will have to support the new API plus any internal changes to support larger transfers.

Impact on Users

Users who opt in to the new API will be able to do larger RMA transfers.


Tickets #80, #97, #98 are closely related.
