Due to COVID-19, the workshop will be organized as a free virtual event using video conferencing, the videos of the presentations will be published on this page.

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 Scientific Computing, Goethe University Frankfurt, Germany), gerbes@fias.uni-frankfurt.de
• Dr. Johannes Doerfert (Compiler Technology and Programming Languages, Argonne National Laboratory, USA), jdoerfert@anl.gov
• Dr. Sameer Shende (Performance Research Lab, University of Oregon, USA), sameer@cs.uoregon.edu
• Dr. Jeremy Bennett (Embecosm, United Kingdom), jeremy.bennett@embecosm.com

The YouTube playlist of the whole workshop is available here.
