+1 From: Tim Bell <Tim.Bell(a)cern.ch<mailto:Tim.Bell@cern.ch>> Date: Thursday, April 16, 2015 at 3:10 AM To: "openstack-operators(a)lists.openstack.org<mailto:openstack-operators@lists.openstack.org>" <openstack-operators(a)lists.openstack.org<mailto:openstack-operators@lists.openstack.org>> Subject: [Openstack-operators] OpenStack HPC/HTC operator session There is an opportunity for a get-together of the people running OpenStack for HPC/HTC workloads at Vancouver. Getting the best of out of the cloud while at the same time meeting the needs of the user communities is a challenging job so sharing experiences for an hour would be really useful. We’re collecting +1s for attendance on openstack-hpc(a)lists.openstack.org<mailto:openstack-hpc@lists.openstack.org> so please reply there if you’d be interested. Tim

Hi. As an aside, I¹d like to add a +1 for a meet up to discuss such things in Vancouver. It would be cool if we could get a meeting room with a few of us together as a focus group Thanks. -jc From: Tim Bell <Tim.Bell(a)cern.ch> Date: Wednesday, 15 April 2015 22:30 To: "openstack-hpc(a)lists.openstack.org" <openstack-hpc(a)lists.openstack.org> Subject: [openstack-hpc] CPU intensive apps on OpenStack Has anyone got suggestions on tuning KVM/OpenStack for running CPU/memory intensive workloads ? There seem to be some standard recommendations like disable EPT in intel-kvm but finding the right combinations of CPU pinning / numa passthrough to get the best performance from the underlying processor has many alternatives.

Vancouver meetup ?
by Tim Bell 07 Apr '15

Would there be interest in trying to get a session at the ops design summit on HPC ? The sessions are being accumulated at https://etherpad.openstack.org/p/YVR-ops-meetup so I would propose we try to get a small working group on OpenStack HPC into the parallel sessions if there is interest. I have put a few ideas down in the etherpad (search for HPC working group) and feel free to add those items you think would be worth discussing. Tim
