Franchetti, Voronenko Part of Winning HPC Challenge Team


December 3, 2010

Assistant Research Professor Franz Franchetti and Ph.D. alumnus Yevgen Voronenko were part of a team that recently took top honors in the HPC Challenge Awards Competition. The goal of the competition, which culminates in an awards ceremony at the yearly Supercomputing Conference, is to focus the high performance computing (HPC) community's attention on developing a broad set of HPC hardware and software capabilities necessary to productively use HPC systems. The HPC Challenge is a novel set of benchmarks to assess performance and productivity of HPC systems and high productivity languages.

The challenge offers two classes of awards: Class 1, Best Performance (on a base or optimized run submitted to the HPC Challenge website); and Class 2, Most Productivity - the most elegant implementation of at least four and at most five computationally intensive kernels. Franchetti and Voronenko were part of an IBM team competing in the Class 2 competition. Led by George Almasi, the IBM team submitted an entry for the two high productivity languages X10 and UPC. Franchetti and Voronenko contributed an implementation of the Global FFT benchmark that was built automatically from a small formal specification using the Spiral system. The entry earned Most Productive System honors.

The HPC Challenge Awards are administrated by DARPA's High Productivity Computing Systems initiative and sponsored by IDC, a premier global provider of market intelligence, advisory services, and events for the information technology, telecommunications, and consumer technology markets.
