Arghya is currently working as Performance Engineer in the Scientific Computing Group at the Oak Ridge National Laboratory. His primary responsibilities are supporting and optimizing Exascale Computing Project applications. His focus is also in optimizing legacy condensed matter physics applications at CNMS, ORNL, using asynchronous programming models such OpenACC, OpenMP, Kokkos and MAGMA. Arghya is leading an effort with the condensed matter physics division to design a shared memory version of the legacy codes (DMRG++ and DCA++) with OpenMP / OpenACC (on node) and a distributed memory version with MPI+X (where X, can be OpenMP or other asynchronous shared memory programming models).
