2024 LLVM Dev Mtg - Instrumenting MLIR Based ML Compilers for GPU Performance Analysis...

2024 LLVM Developers' Meeting https://llvm.org/devmtg/2024-10/ ------ Instrumenting MLIR Based ML Compilers for GPU Performance Analysis and Optimization Speaker: Corbin Robeck ------ Slides: https://llvm.org/devmtg/2024-10/slide... ----- Correlating GPU kernel performance bottleneck analysis information back to program source within modern machine learning frameworks, that use MLIR and JIT style kernels, remains a challenge as it can often be difficult to attribute the performance issue to specific points within the compiler tool chain and the various lowering passes (Python/C++, GPU kernel source, multiple MLIR IRs, LLVM IR, and architecture specific ISA). In this talk we give an overview of a developed set of open source and extendible GPU kernel instrumentation passes to address this issue and how they can be integrated within popular MLIR based machine learning compilers. ----- Videos Edited by Bash Films: http://www.BashFilms.com
