Thanks Rayson!
That did the trick.
Best,
Joseph

Joseph,
You need to set S_DESCRIPTORS, H_DESCRIPTORS with the "execd_params"
option in sge_conf:
http://gridscheduler.sourceforge.net/htmlman/htmlman5/sge_conf.html
Example: H_DESCRIPTORS=10000

Hi All.
I increased our ulimits on our compute nodes and I can request the new
limits if I ssh to the compute nodes:
[root@compute-2-3 security]# tail -5 /etc/security/limits.conf
# End of file
* hard nofile 10240
* soft nofile 4096
* hard nofile 10240
* soft nofile 4096
[user@compute-2-3 ulimit]$ ulimit -aH | grep files
open files (-n) 10240
[user@compute-2-3 ulimit]$ ulimit -n 4096
[user@compute-2-3 ulimit]$ ulimit -aH | grep files
open files (-n) 4096
However, when using GE ( SGE 8.1.2 ) I am not able to see nor request the
higher limit:
$ cat job.sh
#!/bin/bash
#$ -N limits
#$ -q bio@compute-2-3
ulimit -aH | grep files
ulimit -n 4096
[user@hpc]$ cat limits.o54780
open files (-n) 1024
[user@hpc]$ cat limits.e54780
/var/spool/ge/compute-2-3/job_scripts/54780: line 6: ulimit: open files:
cannot modify limit: Operation not permitted
I think I may be missing some entry in /etc/pam.d but I am not sure which
one, or am I missing some other config in GE?
