Yes, without SGE all works, with SGE it does work too if I use a static
machinefile (see initial post), or -H h1,...,hn does work too! Just with
the SGE's generate $TMPDIR/machines file (which in turn is valid! I
checked this), the job doesn't run. And the ulimits are (in every three
possibilities every time) unlimited:
pos1: pdsh -R shh -w node[XX-YY] ulimit -a => unlimited
pos2: qsub jobscribt, where jobscript just calls the command as in pos1
pos3: qsub jobscribt, where jobscript calls another script (containing
the same command as in pos1) and additionally passing $TMPDIR/machines
as argument to it.
Thanks for your help.
