Thanks for the valuable note Reuti. I shall apply the operation also on
each exechost.

Hi All,
Thanks a lot for your valuable suggestions. I just solved the problem by
limiting h_vmem value on qconf -mq.
Great.
Just note, that this setting in the queue definition is a limit per job and not
per exechost - unless you made the complex h_vmem consumable and added a
feasible value to each machine via `qconf -me node001` as outlines in the
provided link.

Hi, All.
When you enable h_vmem, make sure to watch out for h_stack, too.
Otherwise, your programs may fail to start, particularly Matlab and
Python for me.
$ qsub -l h_vmem=2G -l h_stack=128M myjob.sh
Cheers.

As far as I know, you have to define a memory consumable in each host, and
reserve it when submit a process to SGE, e.g. qsub -l h_vmem=2G. Otherwise,
machines memory could start swapping and then crash the machine. Also, this
way, the server also kills those process than consume more memory than
was reserved.

Excerpts from Edrisse Chermak's message of 2013-10-07 16:25:48 +0200:
Dear Grid Engine developers and users,
I would like to prevent jobs running when node memory is almost filled.
Here is the typical situation I have:
'qhost':
================================================================
HOSTNAME ARCH NCPU LOAD MEMTOT MEMUSE
----------------------------------------------------------------
global - - - - -
node1 linux-x64 64 12.00 52.4G 42.8G
node2 linux-x64 64 24.00 52.4G 12.8G
===============================================================
The memory on node1 is almost filled, so I would like the new job I'll
launch to go on node2. (provided that the job I want to launch requires
2 CPUs and that I configured np_load_avg=0.80, so that CPU load doesn't
matter here).
note : I'm using ge2011.1
Thanks in advance,
Best Regards,
Edrisse
