Vinod Tipparaju, research scientist at Oak Ridge National Laboratory (ORNL), will present “Evolution of Supercomputers from Terascale to Exascale and its impact on GAS/PGAS Scientific Applications” at 11 a.m. on Friday, Sept. 10, in 3129 Shelby Center. His seminar is hosted by Auburn University’s Department of Computer Science and Software Engineering.

Tipparaju will discuss the evolution of hardware computer systems and GAS/PGAS models, as well as progress made in global address space and partitioned global address space (GAS/PGAS) models. He will also talk on their development and impact on scientific applications. Because supercomputers are limited by power, researchers who upgrade equipment from terascale to exascale experience challenges that can be resolved by using (GAS) and (PGAS) models and applications for high-performance computing machines (HPC).

Tipparaju is the key architect for next generation PGAS programming models in ORNL’s Future Technologies Group. He previously worked at Pacific Northwest National Laboratory and Telcordia, where he contributed significant developments to the global arrays GAS programming model. Tipparaju’s research interests include network interconnects for HPC systems, runtime systems and collective communication algorithms.
