Open Stack

Hello there,

Very interesting initiative ! I'm currently working on the performance 
side too on our (french astrophysics cloud) OpenStack deployment but to 
say so currently I'm just following what CERN did regarding to Nova/CPU 
configuration.
It's essentially around KSM, NUMA, CPU pinning, EPT and performance 
measures are compared through Spec 06 benchmarks, which is standard for 
HPC/HTC computing.

You can take a look at the very interesting blog from CERN here 
http://openstack-in-production.blogspot.fr/ and if you want I have few 
slides from various meetings like HEPIX on these subjects.

Following the etherpad !

Regards,

> Something that jumped out at me in Tokyo was how much it seemed that "basic" tuning stuff wasn't common knowledge. This was especially prevalent in the couple of rabbit talks I went to. So, in order to pool our resources, I started an Etherpad titled the "OpenStack Tuning Guide" (https://etherpad.openstack.org/p/OpenStack_Tuning_Guide). Eventually I expect this should go into the documentation project, and much of it may already exist in the operators manual (or elsewhere), but I thought that getting us all together to drop in our hints, tweaks, and best practices for tuning our systems to run OpenStack well, in real production, would be time well spent.
