Polyhedral optimizations for LLVM

Registered by LPC Submitter on 2012-08-13

Polly is a polyhedral optimizer run as plug-in to the LLVM compiler. Polly optimizes loops for data-locality, auto-vectorization, and auto-parallelization. Although this tool is still under development, it has been gaining traction in the community over last few months and its quality increased significantly. This session will provide an overview on its current state and discuss the roadmap for production utilization.

Topic Lead: Zino Benaissa
Zino Benaissa is a senior staff engineer at QuIC, Qualcomm’s open source subsidiary, responsible for developing back end optimizations for the LLVM compiler. Before joining Qualcomm in 2011, he worked at Intel for 11 years leading the effort to incorporate Intel micro-architectural tunings into the Microsoft Visual C++ compiler. In particular, the support Advanced Vector Extensions (AVX) and collaborated with Microsoft compiler architects and engineers to bring up the auto-vectorizer in the latest release of Microsoft (Dev11) compiler.
