The Second Workshop on LLVM Compiler and Tools for HPC will be held at ISC-HPC 2021

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. If you are interested in attending the workshop, please register at the ISC-HPC website. Note: The workshop will be virtual, we expect to record the talks and make them available afterwards.

  • Tentative Conference Dates: July 2nd and 3rd, 2021
  • Location: Virtually

In case of any queries please reach out to the workshop organizers: Johannes Doerfert (jdoerfert at, Anja Gerbes (anja.gerbes at, Sameer Shende (sameer at, Jeremy Bennett (jeremy.bennett at

We will have invited talks but are looking for contributions at the same time. We do not expect to have proceedings and submissions can be in the form of a (extended) abstract or preliminary slide-deck. More information is to follow.

Past Attendees

  • Active developers of projects in the LLVM Umbrella (LLVM core, Clang, LLDB, libc++, compiler_rt, klee, lld, OpenMP, etc).
  • Anyone interested in using these as part of another project.
  • Students and Researchers.
  • Compiler, programming language, HPC, runtime and tooling enthusiasts.
  • Those interested in using compiler and toolchain technology in novel and interesting ways.


Panel sessions are guided discussions about a specific topic. The panel consists of ~3 developers who discuss a topic through prepared questions from a moderator. The audience is also given the opportunity to ask questions of the panel.

Birds of a Feather (BoF)

A BoF session, an informal meeting at conferences, where the attendees group together based on a shared interest and carry out discussions without any pre-planned agenda.

Technical Talks

These 20-30 minute talks cover all topics from core infrastructure talks, to project's using LLVM's infrastructure. Attendees will take away technical information that could be pertinent to their project or general interest.


Tutorials are 50-60 minute sessions that dive down deep into a technical topic. Expect in depth examples and explanations.
