Cryptic enough :-) Best I can tell, your TCP comm isn't working. All your procs are failing because they can't talk to each other. I'm also seeing something I don't understand: *** The MPI_Init() function was called before MPI_INIT was invoked. *** This is disallowed by the MPI standard. You

>What does it exactly imply to compile with this option ? Open MPI's internal malloc library (ptmalloc) will not be built/used. If you are using an RDMA capable interconnect such as Infiniband, you will not be able to use the "mpi_leave_pinned" feature. mpi_leave_pinned might improve performance fo

2010-08-15 Thread James R. Leek
I just need to confirm that openmpi 1.4.2 doesn't support nested invocations of mpirun. I found a previous mailing list message the that effect, but it referred to 1.3.3. I really need this functionality, so I wanted to make sure openmpi doesn't have it before I start doing desperate things.
