Biographical Sketch

Rahulkumar Gayatri is an Application Performance Specialist working in the Application Performance Group (APG) at NERSC. His current projects include the the EXAALT ECP project and he is also involved with the Kokkos development team.

In his time as a NERSC staff member, Rahul optimized the SNAP potential in LAMMPS MD package for next generation architectures. He is currently working on the OpenMPTarget backend of the Kokkos programming model.

Rahulkumar Gayatri got his PhD in the area of parallel programming models from Barcelona Supercomputing Center in March 2015 under the supervision of Dr Rosa Maria Badia and Eduard Ayguade. His thesis work was on synchronization of multiple threads on a multi-core processor. 

Later he worked in the HPC group at Wipro Infotech where he provided parallel programming solutions to clients. As a part of this group he worked with the MOOSE project, which simulates the behavior of a cell in a human brain. He parallelized the linear solvers that simulate the effect of chemical and electrical stimuli given to a cell. 

Research Interests

High-performance computing, Parallel computing, Porting scientific computing applications onto Highly parallel machines.
