intMPIAPIMPI_Win_allocate_shared( MPI_Aint size,intdisp_unit, MPI_Info info, MPI_Comm comm, _Out_void*baseptr, _Out_ MPI_Win *win ); parameters 大小 内存窗口的大小(以字节为单位)。 disp_unit 位移的本地单位大小(以字节为单位)。
MPI_Win_allocate_shared(...,comm_shared,..,win_host) // direct/RMA within host Then have each rank perform MPI_Win_create(b_buff_from_Win_allocate_shared,..., win_world) IOW supply the address of the intra-rank buffer to the inter-rank window Jim Dempsey Translate 0 Kudos Copy ...
First of all: Congratulations, that INTEL-MPI now supports also MPI-3 ! However, I found a bug in INTEL-MPI-5.0 when running the MPI-3 shared memory feature (calling MPI_WIN_ALLOCATE_SHARED, MPI_WIN_SHARED_QUERY) on a Linux Cluster (NEC Nehalem) by a Fortran95 CFD...
