Hi, when i run my code i have this error "process 1 exited without calling finalize" what is the cause? although I put a barrier before the end of my code MPI_Init(&argc, &argv); MPI_Comm_rank(MPI_COMM_WORLD, &rang_proc); MPI_Comm_size(MPI_COMM_WORLD, &nbr_proc); //parallel code MPI_Barrier(MPI_COMM_WORLD); MPI_Finalize(); _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
