Invited talk - Johannes Doerfert, Lawrence Livermore National Laboratory
Title : LLVM/Offload --- R&D in the Open
The LLVM/Offload project aims to bring performance portability and language interoperability to the HPC ecosystem and beyond. With a single offloading backend, all frontend languages can share the features, performance improvements, portability enhancements, and even operate within a single application seamlessly. In this talk we will look at LLVM/Offload, what it is, the status, ongoing work, and our roadmap for future improvements. Beyond classical optimizations and portability, we will also look at user-facing features for debugging, tuning, profiling, and correctness checking. In the end, the audience will have a better idea how a variety of efforts, from various parties around the world, is orchestrated in the open to build a better HPC ecosystem for all of us.
