What do you mean by "in the past" - you upgraded SGE from version x
to version y? You can still source <execd-spool>/<nodename>/
<active_jobs>/<job_id>.1/environment.
$ qrsh -pe orte 4 /path/to/binary
If you really need a shell, you can get one with:
$ qrsh -pe orte 4 bash -il
That breaks my shell (erase, history, tab-completion) but it seems
to work other than that. Any suggestions on getting a unique list
of nodes without touching them N times (N=# of slots assigned)? I
guess I could do "mpirun uname -n|sort -u" but that just seems,
well, wrong.
There is nothing stopping you to define a start/stop_proc_args script
anyway. You could use the example in $SGE_ROOT/mpi and then call this
script with -uniq which will give you a list in the usual $TMPDIR/
machines file. You can even create and remove the temporary
directories in this script(s), so you don't have to do it by hand
every time you run an interactive parallel job.

BTW: To avoid saving of the history in the bash and/or sourcing the
environment:
MYPARENT=`ps -p $$ -o ppid --no-header`
MYSTARTUP=`ps -p $MYPARENT -o command --no-header`
if [ "${MYSTARTUP:0:13}" = "sge_shepherd-" ]; then
echo "Running inside SGE"
MYJOBID=${MYSTARTUP:13}
MYJOBID=${MYJOBID% -bg}
echo "Job $MYJOBID"
. /usr/sge/default/spool/$HOSTNAME/active_jobs/$MYJOBID.1/
environment
unset HISTFILE # don't save the history
fi
In any case, thanks for the tips!
