Does Intel MPI Library support passive target one-sided communication? How about the perforamnce? It seems the performance of passive target one-sided operations implemented through MPI-2
windows is very poor. The implementation of RMA in Intel MPI is not truly
one-sided. When a process call MPI_Get/Put, the target process won't response if it is busy on its own work.
Yes it does. Intel MPI Library does supported passive one-sided communication. Performance... I don't know. When you call MPI_Get/Put real communication will not be started until MPI_Win_Fence is called.
