I have following two questions with MPI,
1. Do I need to give a separate input file to each processor in a group or
all of them can read the input from a single file? All data inside the file
should be read by every processor.
2. Can you please tell me what is the difference between
MPI_Neighbor_alltoallw and MPI_Ineighbor_alltoallw? As I read in MPI 3.0
document that MPI_Neighbor_alltoallw also used non-blocking send and
receive inside its execution.
