In my implementation, I did not add any new queue resource limits. If you are adding new resource limit, you will need to change the spooling structure a bit. I am just mapping existing queue limits to the cgroup limits. > * Supplements the existing PDC mechanisms, to allow continued support of > operating systems that do not have cgroups (or equiv mechanism), or > installations who want to use h_vmem. Not sure how you are implementing it... In our implementation we either use cgroups to tag processes or we switch back to the old additional GID PDC completely. Since every single release of Grid Engine distributed by us (Open Grid Scheduler) is fully compatible with SGE 6.2 u5, if one upgrades from SGE 6.2u5 to Grid Engine 2011.11 update 1, the execd & shepherd pair would still behave like SGE 6.2 u5. (The way to enable cgroups PDC is by a config switch.) > How far along with your solution are you? Am I just duplicating work someone > else has already done? We are less than 1 month away from shipping, and we are already running the cgroups code in our test cluster. Also, the qstat, qmod, and cat output capture was from a real session (see: http://blogs.scalablelogic.com/2012/05/grid-engine-cgroups-integration.html ). It was for the Gompute User Group Meeting presentation that took place earlier this month (May 8th and 9th). Gompute User Group Meeting - Grid Engine Track ==================================== BTW, we are planning to have an annual event at the Gompute User Group Meeting. We really need to recreate the annual Grid Engine Workshop. I already have something interesting to announce for the next meeting - ie. a year from now, and yes, we are working on a few long term projects.
