Summary
🤩
Rockstar🎓
Top SchoolPrithayan Barua is a Staff Compiler Engineer with nine years of experience focused on program analysis and compiler optimizations for heterogeneous architectures, currently based in Atlanta and pursuing a PhD in Computer Science at Georgia Tech. He has practical production experience at SiFive and NVIDIA’s GPU Architecture group, and four years working on a C-to-RTL high-level synthesis compiler, Synphony C Compiler. His research and engineering work includes building LLVM optimizations—such as a loop unroll-jam cost model, OpenMP memory-management tooling for target offloading, and GPU kernel optimizations that balance memory-level parallelism and occupancy. He contributes to the LLVM/CIRCT ecosystem, notably enhancing the FIRRTL backend’s memory handling and adding support for RefType, improving compiler robustness for hardware IRs. Known for bridging deep research with shipping optimizations, he combines rigorous academic training (IISc MS, Georgia Tech PhD candidate) with hands-on backend and GPU compiler development. An under-the-hood detail: he’s equally comfortable tuning low-level mask bitwidths in FIRRTL as designing cost models that guide high-level transformation decisions.
