-------------------------------------------------------------------------- It looks like orte_init failed
for some reason; your parallel process is likely to abort. There are many reasons that a parallel
process can fail during orte_init; some of which are due to configuration or environment problems. This
failure appears to be an internal failure; here's some additional information (which may only be relevant
to an Open MPI developer):
orte_ess_init failed --> Returned value A system-required executable either could not be found or
was not executable by this user (-126) instead of ORTE_SUCCESS
--------------------------------------------------------------------------
-------------------------------------------------------------------------- It looks like MPI_INIT failed
for some reason; your parallel process is likely to abort. There are many reasons that a parallel
process can fail during MPI_INIT; some of which are due to configuration or environment problems. This
failure appears to be an internal failure; here's some additional information (which may only be relevant
to an Open MPI developer):
ompi_mpi_init: ompi_rte_init failed --> Returned "A system-required executable either could not be
found or was not executable by this user" (-126) 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) [lgw01-amd64-044:10428] 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!
