Also, something to keep in mind - cgroups will not solve this issue completely.
It is just affinity enforcement. If the job spawns multiple

Hmmm changing the source code is not my intention.
But I'll have a look at the discussion you are referring to and see if I
change my mind.
Thanks

Hi,
sure I can just kill those jobs, but this is exactly what I'd like to avoid.

Hi,
thanks for your reply. This sounds promising.
We are using Son of Grid Engine though. Can you point me to the right
docs to get cgroup enabled in the exec host (CentOS 7). I must admit I
have no experience with cgroups.
Thanks again

At least for UGE, you will want to use the CPU set integration, which will
assign the job to a cgroup that has one CPU per requested slot. Once you
have cgroups enabled in the exec host OS, you can then set these options in
sge_conf:
cgroup_path=/cgroup
cpuset=1
You can use this mechanism to
17 matches
