Graph 500 Takes Aim at a New Kind of HPC

November 15, 2010

Data-intensive applications are quickly emerging as a significant new class of HPC workloads. For this class of applications, a new kind of supercomputer, and a different way to assess them, will be required. That is the impetus behind the Graph 500, a set of benchmarks that aim to measure the suitability of systems for data-intensive analytics applications. Read more…

Should I Buy GPGPUs or Blue Gene?

November 4, 2010

Given the recent ascent of the GPU-powered Tianhe-1A system to the top of the supercomputing heap, a current paper from Department of Computer Science at the University of Warwick should be of particular interest to those in the market for a petascale supercomputer. Essentially their study asks the question: As an organization, should I commit to a platform based on general-purpose GPUs or an IBM Blue Gene? Read more…

Compilers and More: Hardware/Software Codesign

November 2, 2010

There is a growing feeling that merely taking the latest processor offerings from Intel, AMD or IBM will not get us to exascale in a reasonable time frame, cost budget, and power constraint. One avenue to explore is designing and building more specialized systems, aimed at the types of problems seen in HPC, or at least at the problems seen in some important subset of HPC. Of course, such a strategy loses the advantages we've enjoyed over the past two decades of commoditization in HPC; however, a more special purpose design may be wise, or necessary. Read more…
