Parallel Systems Group

The Parallel Systems Group carries out research to facilitate the use of extreme scale computers for scientific discovery. We are especially focused on tools research to maximize the effectiveness of applications running on today’s largest parallel computers. Our expertise includes performance measurement, analysis, and optimization in addition to debugging and power optimization. We also have expertise in existing and new programming models, power-aware supercomputing, fault tolerant computing, and numerical kernel optimization.
