I have a loop in which I will do some MPI_Isend. According to the MPI standard, for every send you need a recv!!!!
If one or several of my MPI_Isend have zero size buffer, should I still have the mpi_recv or I can do it without recv? I mean on the processor which I should recv the data I know priory that my buffer is with zero size. Can I jump from MPI_Recv. The question is because of the format of the program I am using if it knows that the receiving buffer is zero it will not call the routine which contains mpi_Recv.
