Hi Cole:
That link you posted refers to our work at ISI. We're currently running LXC as
the hypervisor on our SGI UV. Other than performance, one of the issues with
KVM is that it currently has a hard-coded limit on how many vCPUs you can run
in a single instance, so we can't run, say, a 256

Hello,
Here at Mirantis we are working on deployment of Openstack that intended to
manage HPC cluster eventually. There are few features that we are going to
incorporate, and we are still researching. The general idea is to use LXC
as a lightweight virtualization engine, and make use of faster
Good point ... thanks for the clarification.

You did see that Amazon hit #42 on the Top 500 supercomputing list? It is
somewhat of a stunt, but the point is that access to a supercomputer is a
credit-card swipe away and rentable by the hour. There was a lot of buzz at
SC11 a few weeks ago.
There are several HPC groups in the OpenStack

An HPC way of usage for.openstack at.mercadolibre is for example to run
integration and regresions test on productios pre and post deploy too. So
Jenkins servers are shooted in a minute to support the tests load and then
they destroy themselves.
