The LLVM framework is a vast ecosystem surrounding a compiler core which enabled various advances in source-code tools, debuggers, linkers, and a whole host of programming-language and toolchain-related components. Similar to the very successful LLVM-HPC workshop at SuperComputing (SC), we want to provide a forum for LLVM-related discussions and talks from academia and industry at ISC.

The workshop is held in conjunction with the ISC-HPC during the ISC workshop day.

This workshop is powered by LLVM.

The workshop is organized by

• Anja Gerbes (Center for Information Services and High Performance Computing, Technische Universität Dresden, Germany), anja.gerbes@tu-dresden.de
• Dr. Johannes Doerfert ( Compiler Technology and Programming Languages, Lawrence Livermore National Laboratory, USA), doerfert1@llnl.gov
• Dr. Sameer Shende (Performance Research Lab, University of Oregon, USA), sameer@cs.uoregon.edu
• Lewis Revill (Embecosm, United Kingdom), lewis.revill@embecosm.com

  GCC – OpenMP, OpenACC and Offloading – Status and Performance Analysis
  A short report on GCC's OpenMP and OpenACC implementation status is given with special focus on the offloading support to AMD and Nvidia GPUs. We then highlight a few implementation details and knobs that users can turn. We round off with performance analysis ideas from a compiler-developer's point of view.

The workshop is integrated into ISC-HPC. We welcome everybody to join the workshop, including:

• Researchers/Engineers from industry and academia working on high-performance computing
• LLVM developers
• Interested domain scientists and computer scientists interested in discussing compiler issues.
