I'm not seeing any cores -- I'll see if there's anything stopping them from being produced.
I've attached to one of the hanging "a.out"s (this is with the "mpiexec" invocation that includes "--mca oob_tcp_include eth0") (gdb) bt #0 0x001e3007 in sched_yield () from /lib/tls/libc.so.6 #1 0x00512b55 in opal_progress () at runtime/opal_progress.c:306 #2 0x00298f57 in opal_condition_wait (c=0xbf5120, m=0xbf5180) at ../../../../opal/threads/condition.h:74 #3 0x00298877 in mca_pml_ob1_recv (addr=0x0, count=0, datatype=0xbe8ce0, src=-1, tag=-16, comm=0xbf0440, status=0x0) at pml_ob1_irecv.c:102 #4 0x002b7ff2 in mca_coll_basic_barrier_intra_lin (comm=0xbf0440) at coll_basic_barrier.c:70 #5 0x00b4dbfa in PMPI_Barrier (comm=0xbf0440) at pbarrier.c:52 #6 0x00b8d257 in mpi_barrier_f (comm=0x804b92c, ierr=0x8052580) at pbarrier_f.c:66 #7 0x080494a8 in MAIN__ () at Halo.f:32 #8 0x0804b7e6 in main () (gdb) up #1 0x00512b55 in opal_progress () at runtime/opal_progress.c:306 306 sched_yield(); (gdb) up #2 0x00298f57 in opal_condition_wait (c=0xbf5120, m=0xbf5180) at ../../../../opal/threads/condition.h:74 74 opal_progress(); (gdb) up #3 0x00298877 in mca_pml_ob1_recv (addr=0x0, count=0, datatype=0xbe8ce0, src=-1, tag=-16, comm=0xbf0440, status=0x0) at pml_ob1_irecv.c:102 102 opal_condition_wait(&ompi_request_cond, &ompi_request_lock); (gdb) up #4 0x002b7ff2 in mca_coll_basic_barrier_intra_lin (comm=0xbf0440) at coll_basic_barrier.c:70 70 err = MCA_PML_CALL(recv(NULL, 0, MPI_BYTE, MPI_ANY_SOURCE, (gdb) up #5 0x00b4dbfa in PMPI_Barrier (comm=0xbf0440) at pbarrier.c:52 52 err = comm->c_coll.coll_barrier(comm); (gdb) up #6 0x00b8d257 in mpi_barrier_f (comm=0x804b92c, ierr=0x8052580) at pbarrier_f.c:66 66 *ierr = OMPI_INT_2_FINT(MPI_Barrier(c_comm)); (gdb) up #7 0x080494a8 in MAIN__ () at Halo.f:32 32 CALL MPI_BARRIER(MPI_COMM_WORLD,MPIERR) Current language: auto; currently fortran (gdb) Does this help?
