[Mpi-forum] [Mpi3-rma] [EXTERNAL] Re: Disp_unit in allocate_shared should be returned by win_shared_query?

[Rolf Rabenseifner]

I'll come back to the technical discussion in a few minutes
with a proposal based on Brian's technical argument:

since a process will have to know the other rank's disp_unit to 
do the memcpy during the communication operations, so we crossed 
the O(p) bridge when we added disp_unit to allocate_shared.
