Hi,
Thanks all who answered. The problem was indeed in the max. locked
memory limitation.
Though, changing it in <SGE_ROOT>/default/common/settings.sh was not enough.
I also had to add ". <SGE_ROOT>/default/common/settings.sh" to
<SGE_ROOT>/default/common/sgeexecd (and to /etc/init.d/sgeexecd on the
compute nodes) as when the sgeexecd was executed boot it ignored the
limits.conf.

I suspect that your SGE daemons are not starting with the proper
locked memory limits (and therefore jobs started under SGE get
severely limited locked memory limits).
See these FAQ entries -- the issues described for SLURM are
applicable to all resource managers (to include SGE):

Hi,
I am running openmpi-1.2.3 compiled for 64bit on RHEL4u4.
I also have a Voltaire InfiniBand interconnect.
When I manually run jobs using the following command:
/opt/local/openmpi-1.2.3-gcc4/bin/orterun -np 8 -hostfile ~/myHostList
-mca btl self,openib /tcc/eandm/performance/igor/main.exe.openmpi123
The job is executed just fine..
Though, when run through SGE I have the weirdest problem, and get the
following error (on all hosts in my list):
----------------------------------------------------------------------
----
The OpenIB BTL failed to initialize while trying to create an internal
queue. This typically indicates a failed OpenFabrics installation or
faulty hardware. The failure occured here:
Host: node4.grid.technion.ac.il
OMPI source: btl_openib.c:828
Function: ibv_create_cq()
Error: Invalid argument (errno=22)
Device: mthca0
You may need to consult with your system administrator to get this
problem fixed.
----------------------------------------------------------------------
----
To send a job to the grid I use the following command:
qrsh -cwd -q noam.q -pe orte 8 ./myScript
while "myScript" looks like:
#!/bin/bash
/opt/local/openmpi-1.2.3-gcc4/bin/orterun -np $NSLOTS -mca btl
self,openib /tcc/eandm/performance/igor/main.exe.openmpi123
If I change "openib" to "tcp" (in myScript) everything works just
fine.
Any ideas?
