Swiss Researchers Propose 'GreenIT' Methodology for HPC

(11/19/2010) - The latest Green500 list announced this week at SC10 is once again shining the spotlight on the energy efficiency of the world's top supercomputers. But the path to more efficient high performance computing goes beyond this simple benchmark-based approach. Ralf Gruber and Vincent Keller, both from École Polytechnique Fédérale de Lausanne (EPFL), describe a holistic approach to more energy-efficient HPC operations in their book, HPC@GreenIT. HPCwire contributor Steve Conway interviewed the Swiss duo about their ideas, including a new benchmark.

Run-Up to Petaflops

(06/18/2008) - There is no other way to characterize this year: 2008 will be remembered as "the year" -- the year that one petaflops was achieved in Linpack performance. It is a milestone that has been anticipated for almost a decade and a half, and one that was accomplished through the synthesis of two big trends that have emerged as the driving forces for HPC in the last few years -- multicore and heterogeneous computing.

IBM Roadrunner Takes the Gold in the Petaflop Race

(06/09/2008) - Petaflop. Sure it's just a number, but it's a big number. On June 10, IBM announced that its Roadrunner supercomputer reached a record-breaking one petaflop -- a quadrillion floating point operations per second -- using the standard Linpack benchmark. It is the first general-purpose computer to reach this milestone.
