Summary
👤
Senior🎓
Top SchoolSarat Sreepathi is a Computer Scientist and HPC advisor with two decades of experience tuning and readying the world’s fastest supercomputers for large-scale Earth system and fusion modeling. As Performance Coordinator for DOE’s E3SM he led a distributed team across national labs to achieve record-setting throughput on Frontier and helped secure the 2023 ACM Gordon Bell Special Prize for Climate Modeling. He has driven GPU strategy and co-design across multiple vendors and architectures, translating low-level compiler and pointer-association fixes (notably in the ESMCI/cime codebase) into production-ready, scalable climate simulations. Skilled at proposal writing and cross-organizational leadership, he combines deep algorithmic and parallel performance expertise with hands-on systems work and a track record of winning resources for high-visibility projects. Unusually, he pairs exascale performance tuning with practical build-system and compiler work, bridging the gap between application science and vendor hardware/software stacks.

Back-end Developer
Back-end DeveloperContributions:10 reviews, 53 commits, 2 PRs in 3 years 11 months
Contributions summary:Sarat primarily contributed to addressing compiler-specific bugs within the project, specifically related to pointer association issues encountered with the PGI compiler (version 17.9) on the Summitdev platform. Their work involved implementing workarounds, such as adding dummy variables to check pointer association status, to prevent runtime crashes. They also made changes to the project's documentation and build configurations.
