====== LLVM-CTH: The Fifth Workshop on LLVM Compiler and Tools for HPC ======

{{  :events:2021:llvmwyvernbig.png?300|}}

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 [[http://www.isc-hpc.com/|ISC-HPC]] during the ISC workshop day.


|| Date || Thursday, May 16th, 2024 ||
|| Venue || Hamburg, further details on [[https://www.isc-hpc.com/travel.html]]  ||
