An experimental OpenMP runtime-library implementation built on top of the XKaapi runtime system, and an extended LLVM's Clang ABI.
You must have an installation of
- XKRT
- patched LLVM - and compile your openmp program with it
Example of LLVM build
cmake ../llvm -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_ENABLE_RUNTIMES="openmp;offload" -DLLVM_TARGETS_TO_BUILD="NVPTX;X86" -DCMAKE_INSTALL_PREFIX=~/install/llvm/debug
Example of XKOMP build
cmake -DCMAKE_BUILD_TYPE=Debug ../
Example of application build
clang -fopenmp main.c -o main -lxkomp
XKRT is a fork of XKaapi, that it extended with support for task dependencies over intersecting regions of memory (https://gitlab.inria.fr/xkaapi/dev-v2) This repo is an abstraction layer to OpenMP through LLVM and GCC ABIs. It partial support of OpenMP 6.0 on taskgraphs (6.0) and original extensions for multi-devices dataflow.
