The Third Workshop on LLVM in Parallel Processing (LLPP) will be held at ICPP 2023

The LLVM framework is a vast ecosystem that stretches far beyond a "simple" C/C++ compiler. The variety of programming-language and toolchain-related parts includes the components to support a host of parallel programming models and libraries, including CUDA, HIP, OpenMP, SYCL, and the C++ parallel algorithms. In addition, LLVM serves as a vehicle for various languages in which parallelism is a first class citizen, such as Julia or Chapel. The workshop is held in conjunction with the ICPP during the workshop day. If you are interested in attending the workshop, please register at the ICPP website.
