Arghya is a Performance Engineer in the Scientific Computing Group (SciComp), National Center for Computational Sciences (NCCS) at the Oak Ridge National Laboratory. His primary responsibilities are supporting and optimizing Exascale Computing Project (ECP) [PI: Dr. Jackie Chen; Pele / S3D] and Center for Accelerated Application Readiness (CAAR) [PI: Dr. Sunita Chandrasekaran; PIConGPU] applications for the Frontier supercomputer.

Arghya is also supporting a SciDAC (Scientific Discovery through Advanced Computing) effort (PI: Dr. Thomas Maier; DCA++) on both research capacity and as a liaison for the Oak Ridge Leadership Computing Facility’s (OLCF) INCITE project.

Prior to the R&D Staff Assistant position, Arghya worked as a Post Master’s Research Associate at the ORNL for a year. where his research focussed on optimizing legacy condensed matter physics applications at ORNL, using asynchronous programming models and hardware optimizations. Arghya is currently enrolled in the PhD program at Georgia Tech (Current Status: PhD Candidate).

Prior to joining Georgia Tech, Arghya completed his MS in Computer Science from Rice University where his research was focused on runtime systems on multicore machines, asynchronous programming models (primarily focused on the Actor model) and exploiting parallelism on Android devices.
