+# some versions of LSF do not reliably return an exit code from
+# a serial section of a batch script, only the return from the 
+# last call to mpirun.lsf.  so to make a batch script really exit
+# in case of error, call this:
+# 
+#  setenv LSB_PJL_TASK_GEOMETRY "{(0)}"   # optional
+#  setenv EXITCODE -1
+#  mpirun.lsf shell_exit.sh
+#
+
+# if you call this inline with an arg:
+if [[ $# -gt 0 ]]; then
+   EXITCODE=$1
+fi
+
+# if you set an env var (the normal way to pass in
+# a value if using mpi):
+if [[ "$EXITCODE" == "" ]]; then
+   EXITCODE=0
+fi

+echo exiting with status code $EXITCODE
+exit $EXITCODE
