[CentOS] /etc/security/limits.conf : rss

[Christophe Caron]

Hello,

I run CentOS 5.6 on a Dell PowerEdge R815 with 256 GB of RAM.
We use Sun Grid Engine to schedule jobs on this node.

I want to limit the memory usage about 150 GB per process.


/etc/security/limits.conf
...
#
*       hard    rss     150000000
*       soft    rss     150000000
#
*       hard    as      150000000
*       soft    as      150000000
#
...

# uname -r
2.6.18-238.9.1.el5.centos.plus


Any idea ?

Thanks

So i use the /etc/security/limits.conf configuration file. I test this configuration with some tools with a lower GB limit (about 2 or 4 GB), and it works ! But, at least one process (oases - a bioinformatics tool) bypass this limitation and use always 240 GB of memory (the last run) !! tél: +33 (0)2 98 29 25 43 / tél: +33 (0)6 07 83 54 77 fax: +33 (0)2 98 29 23 24 Analysis and Bioinformatics for Marine Sciences Platform http://abims.sb-roscoff.fr/
