WebThe "all" setting (1) invokes the MPI_All2all() method within subsets of processors that need to exchange data. The "combo" setting (2) is a combination of the other options. It invokes point-to-point MPI methods for pencil-to-brick data movement, and the all2all MPI method for pencil-to-pencil data movement. WebMPI_Alltoall, and it should behave the same way for all arguments. (Note: you do not need to implement the "in place" option.)

WebDescription The shmem_alltoalls routines are collective routines. Each PE in the Active set exchanges nelems strided data elements of size 32 bits (for shmem_alltoalls32) or 64 bits (for shmem_alltoalls64) with all other PEs in the set. Both strides, dst and sst, must be greater than or equal to 1.
