From a performance point of view, which one is better: MPI_Battach(10*sizeof(MSG)) MPI_Brecv() or MPI_recv_init() MPI_recv_init() MPI_recv_init() ... /* 10 recv handlers */ MPI_Start(all recv) MPI_Waitany()I understand MPI_Brecv will require an extra message copy, from the attached buffer to the MPI_Brecv() buffer. I'd like to know if there other differences between the two methods.Thanks, Rob _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
