[slurm-users] Swap Configuraton for compute nodes

[Hermann Schwärzler]

Hi Eg.

if you are using cgroups (as you do if I read your other post correctly) 
these two lines in your cgroup.conf should do the trick:

ConstrainSwapSpace=yes
AllowedSwapSpace=0

Regards,
Hermann

PS: BTW we are planning to *not* use this setting as right now we are 
looking into allowing jobs to swap/page when they have exhausted their 
requested memory.
Until now our impression is that this has an impact on the respective 
job only and not on the whole compute node. But maybe we are wrong...
