Sreepathi Pai is a postdoctoral research fellow at the Institute for Computational Engineering and Sciences at the University of Texas, Austin. Sreepathi's research interests are in compilers and computer architecture for high-performance computer systems that feature accelerators like GPUs. Most recently, his work has revolved around optimizing compilers for high-performance irregular/graph algorithms on GPUs, including developing performance models for graph algorithms on GPUs. This work has led to the LonestarGPU 2.0 suite of GPU graph benchmarks and the IrGL compiler for irregular GPU algorithms. He obtained his Ph.D. in 2015 from the Indian Institute of Science, Bangalore, where he worked on schemes for minimally redundant automatic memory transfers between the CPU and GPU, and on improving concurrent execution capabilities in GPUs.
