#1459 duplicate USE_CGROUPS sets host in error state mikaelb

I have been testing the USE_CGROUPS option that is available to execd. When USE_CGROUPS is enabled it works fine to submit a single job to a queue instance on an execution node. However, if a second job is submitted to the same queue instance, it fails and sets the queue instance in error state due to that the shepherd exited with return code 7. The shepherd trace gives the this:

Shepherd trace:
03/13/2013 22:39:47 [0:17310]: shepherd called with uid = 0, euid = 0
03/13/2013 22:39:47 [400:17310]: starting up 8.1.3
03/13/2013 22:39:47 [400:17310]: can't open file pid: Permission denied

Jobs that successfully start have job spool directories owned by the gridadmin administrative user (the user SGE runs as), while the spool directories of the failed jobs are still owned by root. If I turn off USE_CGROUPS everything works ok. Initially I thought this was som race condition which can be triggered when jobs are started rapidly, but some more testing showed that it was when a second job was started on the same execution host.

#1476 duplicate Add a per-host consumables and resource maps like in Univa Grid Engine michel

Univa Grid Engine has implemented a very interesting system, allowing a "per host consumable" :

This allows for example a pe job to request N Slots and 1 complex within the same job.

In OGS, asking for a pe of N slots with a consumable complex leads to asking N time the complex and give the following message in the scheduling info: cannot run in PE "default" because it only offers 0 slots

#1491 fixed Support -sys-jemalloc option opoplawski

OGS's aimk has a -sys-jemalloc option which allows building with the system's jemalloc library. Please support. This basically does:

   case "-sys-jemalloc":
