Yes I posted the same question to the sun grid engine mailing list, and
as Jeff initially supposed it was the inproper limits for the daemons
(sgeexec). So I've to edit each node's init script
(/etc/init.d/sgeexecd), and put "ulimit -l unlimited" before starting
sge_execd. Then kill all sgeexecd's (running jobs won't be affected if
you use "qconf -ke all") then restart every node's sgeexecd. After that
every thing with SGE and OMPI 1.1.1 was fine.
But for the whole question just read the small thread at:
At this point big thanks to Jeff, and all other which helped me!
Are there any suggestions to the compilation error?
many many thousand thanks for the great help here in the forum!
