Hi Ulrich,
In this case, you can use the option -machinefile $TMPDIR/machines instead of
specifying all hosts.
SGE creates the temporary file $TMPDIR/machines which contains the assigned
machines.

Objet : Re: [gridengine users] CPU allocation SOLVED
Hi again,
i know i should have answered earlier, but in the meantime the problem
seems to be solved. A colleague found out that in the command line the
host option has to be added with all the nodes (which was not the case
in earlier versions - so i was seeking at the wrong place).
So the command should look like this:
mpirun -np $NSLOTS -host node1,node2,node3,...,noden -prefix
my-prefix-if-necessary mycode.py
Again thanks a lot for all your help, Farid and especially Reuti.
With kind regards, ulrich
