CERN is more of a high throughput computing environment rather than a high performance site. Although we do multi-core, our programs are not the large scale floating point programs of some other sciences, so GPUs etc. are not a significant gain for us.
CERN is currently targeting a pre-production service based on OpenStack this year and targetting around 15,000 hypervisors spread across two data centres by 2015.
