Summary
🤩
Rockstar🎓
Top SchoolPrithayan Barua is a Staff Compiler Engineer at SiFive and a PhD candidate in Computer Science at Georgia Tech, focused on program analysis and compiler optimizations for heterogeneous architectures. He brings eight years of deep compiler experience, from C-to-RTL high-level synthesis (Synphony C Compiler) to working with NVIDIA’s GPU Architecture group on a Volta compiler. His contributions include a loop unroll‑jam cost model, an OpenMP memory-management tool for LLVM offloading, and optimizations that trade off memory-level parallelism and occupancy for GPU kernels. He’s also an active backend contributor to LLVM/CIRCT’s FIRRTL compiler, improving memory handling and RefType support, blending research rigor with production-grade compiler engineering.
