I didn't see any "xterm" strings in there, but ok. :-) I ran with orte/test/mpi/intercomm_create.c, and that hangs for me as well: ----- ❯❯❯ mpicc intercomm_create.c -o intercomm_create ❯❯❯ mpirun -np 4 intercomm_create b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank 4] b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank 5] b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank 6] b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank 7] c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 4] c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 5] c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 6] c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 7] a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) [hang] ----- Similarly, on my Mac, it hangs with no output: ----- ❯❯❯ mpicc intercomm_create.c -o intercomm_create ❯❯❯ mpirun -np 4 intercomm_create [hang] ----- > George. > > On Sep 18, 2013, at 07:53 , "Jeff Squyres (jsquyres)" <jsquy...@cisco.com> > wrote: > >> George -- >> >> When I build the SVN trunk (r29201) on 64 bit linux, your attached test case >> hangs: >> >> ----- >> ❯❯❯ mpicc intercomm_create.c -o intercomm_create >> ❯❯❯ mpirun -np 4 intercomm_create >> b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank >> 4] >> b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank >> 5] >> b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank >> 6] >> b: MPI_Intercomm_create( intra, 0, intra, MPI_COMM_NULL, 201, &inter) [rank >> 7] >> a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) >> a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) >> a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) >> a: MPI_Intercomm_create( ab_intra, 0, ac_intra, 0, 201, &inter) (0) >> c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 4] >> c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 5] >> c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 6] >> c: MPI_Intercomm_create( MPI_COMM_WORLD, 0, intra, 0, 201, &inter) [rank 7] >> [hang] >> ----- >> >> On my Mac, it hangs without printing anything: >> >> ----- >> ❯❯❯ mpicc intercomm_create.c -o intercomm_create >> ❯❯❯ mpirun -np 4 intercomm_create >> [hang] >> ----- >> >> >> On Sep 18, 2013, at 1:48 AM, George Bosilca <bosi...@icl.utk.edu> wrote: >> >>> Here is a quick (and definitively not the cleanest) patch that addresses >>> the MPI_Intercomm issue at the MPI level.
