There is only a single process, I was reading it as relating to include threads within a single process, but they should clearly be able to serialize this withing a single process, so hoping my reading is not correct. >What openstack package are you using? 2012.2-0ubuntu5~cloud0 on Ubuntu 12.04 from Ubuntu cloud-archive. With further testing it appears the allocation ratios are simply being ignored as the ChanceScheduler also violates my resource allocation limits I just hadn't been testing at large enough scale to reliably see it. I am seeing memory allocations >1.5 default ram_allocation_ratio which is somewhat curious. So it's almost as if the RamFilter isn't filtering rather than falling back to the default allocation ration (the compute nodes would melt before I got to the 16:1 default cpu allocation ration so not surprised I'm not getting near that more like 2:1) again despite: scheduler_available_filters=nova.scheduler.filters.standard_filters scheduler_default_filters=AvailabilityZoneFilter,RamFilter,CoreFilter,ComputeFilter,RetryFilter cpu_allocation_ratio=1.0 ram_allocation_ratio=1.0 Thanks, -Jon _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
