Hi folks, We have submitted for two speaking slots in the upcoming design summit summit. Now is the time to vote for them, if it's something that you're interested in. The first link, is a overview of the state of the art in HPC within OpenStack, featuring Tim Bell, Gegor von Laszewski, Patrick Petit, and myself. http://www.openstack.org/rate/Presentation/technical-computing-with-opensta… The second is a technical discussion about VM access to devices like GPUs and Infiniband interfaces featuring Andrew Younge, a visiting researcher at ISI. http://www.openstack.org/rate/Presentation/building-high-performance-clouds… Voting ends Aug. 25. Please consider voting for these so that HPC is well represented at the Hong Kong summit. best, JP
