Package: openmpi-bin Version: 3.1.1.real-4+b1 Severity: grave Justification: renders package unusable
Dear Maintainer, since the latest wave of package updates (gnu compilers big version switch + new openmpi package) even the simplest code, compiled by mpicc.openmpi (or mpif90.openmpi) hangs forever on first initialisation of MPI. Even the following "hello world" does it on my machine: #include <mpi.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <stdio.h> #include <math.h> #include <ctype.h> #include <unistd.h> int main(int argc, char **argv){ int nprocs=0, myrank=0, ierr=0; ierr = MPI_Init( &argc, &argv); ierr = MPI_Comm_rank(MPI_COMM_WORLD, &myrank); ierr = MPI_Comm_size(MPI_COMM_WORLD, &nprocs); printf("MPI_Init call ok\n"); printf("My rank is = %d\n", myrank); printf("number of procs is = %d\n", nprocs); printf("\n"); ierr = MPI_Finalize(); printf("MPI_Finalize call ok, returned %d\n", ierr); return 0; } Of course, this makes the package completely unusable for me. I don't know whether this can be related to bug #584699: in fact my laptop is not really multihomed. Please let me know if there is something I can do to help pinpoint this. By the way, the above snippet of code works perfectly if compiled and run under mpich.
