Re: [Beowulf] Hyper Convergence Infrastructure

Without giving specific names of technologies, hypervisors can reduce around 5-10% the performance. I tested linpack and stream and I got small reduction ~5%. For networking: bandwidth about 5%, for latency about 10% reduction. On hyperconverged, since data is replicated, the write performance is h

Hello David. Please visit this link for some answers to your questions. https://www.nersc.gov/research-and-development/archive/cloud-computing/ I have worked on HPC, Cloud, Virtualization, Hadoop and hyperconverged projects. I think the challenge is to understand where each of these "computing fra

Very nice article. Are cray computers still made, and how popular are they? How pricey are they? :) On Fri, Oct 2, 2015 at 11:42 AM, John Hearns wrote: > http://www.theregister.co.uk/2015/10/02/seymour_cray_90_anniversary/ > > > > > > I remember learning about Gallium Arsenide and Emitter Couple
