Do Processors Really Matter Anymore?
But now that processors have gotten so powerful and the ability to pool them has been simplified, is it time to start wondering whether the old ways of placing value on new equipment are no longer valid?

Science at Scale: SciDAC Astrophysics Code Scales to Over 200K Processors
MAESTRO, a low Mach number code for studying the pre-ignition phase of Type Ia supernovae, as well as other stellar convective phenomena, has just been demonstrated to scale to almost 100,000 processors on the Cray XT5 supercomputer “Jaguar” at the Oak Ridge Leadership Computing Facility. And CASTRO, a general compressible astrophysics radiation/ hydrodynamics code which handles the explosion itself, now scales to over 200,000 processors on Jaguar—almost the entire machine. Both scaling studies simulated a pre-explosion white dwarf with a realistic stellar equation of state and self-gravity.

Parallel Studio Meets Visual Studio 2010
Intel’s James Reinders talks with Steve Teixeira, Product Unit Manager for Parallel Developer Tools at Microsoft, about the new Visual Studio’s support for parallel programming.

Supercomputer helps telescope see echos from the big bang
An international collaboration of scientists has announced the first results of the ACT project, probing the early years of the Universe, at Canada’s largest supercomputing conference in Toronto today. The presentation was made by Jonathan Sievers, of the Canadian Institute for Theoretical Astrophysics.


  1. I have a few comments about the statement “It would seem, though, that the only users still focusing on clock speeds and overall processing capability are in the HPC market” in the first article above “Do Processors Really Matter Anymore?” See my HPCatDell blog post at
