Hi, Jeff

many thanks for your reply..

Hmm, I've heard about conflicts with OMPI 1.2.x and OFED 1.1 (sorry no
refference here), and I've got no luck producing a working OMPI
installation ("mpirun --help" runs, and ./IMB-MPI compiles and runs too,
but "mpirun -np 2 node03,node14 IMB-MPI1" doesnt (segmentation
fault))... (beside that, I know that OFED 1.1 is quite old too) So I'm
tested it with OMPI 1.1.5 => same error.

yes I allready read the faq, and even setting them to unlimited has
shown not be working. In the SGE one could specify the limits to
SGE-jobs by e.g. the qmon tool, (configuring queues > select queue >

the job is running with a static machinefile (is this an
"noninteractive" job?)) How could I test ulimits of interactive and
noninteractive jobs?

Thank you for your great help.
