Summary
🤩
Rockstar🎓
Top SchoolScott Manley is a Principal Compiler Engineer with nine years of professional experience focused on compiler optimizations, autovectorization, and high-performance CPU tuning for SIMD ISAs like x86 AVX/AVX512 and Arm Neon/SVE. Currently at NVIDIA after a long tenure at Cray, he leads CPU performance and autovectorization efforts for the NVIDIA HPC SDK and contributes to upstream compiler projects such as LLVM/MLIR and Flang. His work spans deep performance engineering—floating-point optimizations, complex lowering, and math library tuning—combined with practical build and tooling fixes that keep large toolchains healthy. A PhD-trained compiler specialist based in Minneapolis, he blends research-grade understanding with hands-on production delivery, and is notable for contributing MLIR features and Fortran front-end improvements to one of the most influential open-source compiler projects.
