Simple wrapper for Sun Grid Engine's qrsh that propagates SGE environment variables and enables X forwarding
#!/bin/sh | |
# David Jones and Will Furnass (University of Sheffield) | |
# `qrsh` is often the most convenient utility for starting interactive shell | |
# sessions on Sun/Son of Grid Engine (SGE) clusters but it has some limitations (as | |
# configured on the ShARC/Iceberg clusters): | |
# | |
# - none of the standard SGE environment vars (e.g. JOB_ID, PE_HOSTFILE, | |
# NSLOTS) that are defined in qsub/qsh batch/interactive sessions are set | |
# (annoying but not the end of the world); | |
# - variables can't be set in prolog scripts (e.g. the CUDA_VISIBLE_DEVICES env | |
# var needed for exclusively locking GPUs to jobs); | |
# - X display forwarding doesn't work. | |
# | |
# This script addresses these three issues. It starts a qrsh shell session in | |
# which: | |
# | |
# - all environment variables set by the scheduler (e.g. JOB_ID) are set | |
# - X display forwarding is enabled if necessary | |
exec qrsh $( [ -z ${DISPLAY+x} ] || echo '-v DISPLAY' ) -pty y "$@" $SHELL |
