Summary

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.
