Re: [Beowulf] China Wrests Supercomputer Title From U.S.

With regard to networks, a near-future fork in the road between Beowulf clusters versus supercomputers may be the intelligence concerning global memory added to the network interface chip for upcoming models of supercomputers. An example is the SGI Ultraviolet series, but also, other supercompute

Hi Bill, list Here is it from The Register: http://www.theregister.co.uk/2010/10/28/china_tianhe_1a_supercomputer/ Which real real production applications ran on Jaguar across all processors? I heard of large high-resolution climate models that ran on Jaguar and on Kraken, using about 6000 cores

RE: [Beowulf] China Wrests Supercomputer Title From U.S.

I was just going to post the same thing, but with the HPCWire link instead. http://www.hpcwire.com/blogs/New-China-GPGPU-Super-Outruns-Jaguar-105987389.html A few comments: A 42% increase (2.5TF v. 1.75TF for jaguar) is not a "wide margin". If I did my math right, that represents about 7 month

RE: [Beowulf] Looking for references for parallelization and optimization

If you are looking for more theoretical approaches, there is always John Reif’s book: John Reif (ed), “Synthesis of Parallel Algorithms”, published by Morgan Kaufmann, Spring, 1993. http://portal.acm.org/citation.cfm?coll=GUIDE&dl=GUIDE&id=562546 It is a weighty tome
