[c426-123.stampede2.tacc.utexas.edu:31927] mca_base_component_repository_open: unable to open mca_ess_singleton: /usr/lib/x86_64-linux-gnu/openmpi/lib/openmpi3/mca_ess_singleton.so: failed to map segment from shared object (ignored)
--------------------------------------------------------------------------
A requested component was not found, or was unable to be opened.  This
means that this component is either not installed or is unable to be
used on your system (e.g., sometimes this means that shared libraries
that the component requires are unable to be found/loaded).  Note that
Open MPI stopped checking at the first component that it did not find.

Host:      c426-123.stampede2.tacc.utexas.edu
Framework: ess

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_base_open failed
  --> Returned value Not found (-13) instead of ORTE_SUCCESS
