There are many reasons that a parallel process canfail during MPI_INIT; some of which are due to configuration or environmentproblems.  This failure appears to be an internal failure; here's someadditional information (which may only be relevant to an Open MPIdeveloper):  ompi_mpi_init: ompi_rte_init failed  --> Returned "The system limit on number of children a process can have was reached" (-119) instead of "Success" (0)--------------------------------------------------------------------------*** An error occurred in MPI_Init*** on a NULL communicator*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,***    and potentially your MPI job)[c401-003.stampede2.tacc.utexas.edu:41034] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!Command exited with non-zero status 1{"realtime":3.89,"usertime":2.87,"systime":8.33,"memmax":64240,"memavg":0}
