Table of contents

Overview

AOMP is a scripted build of LLVM and supporting software. It has support for OpenMP target offload on AMD GPUs. Since AOMP is a clang/llvm compiler, it also supports GPU offloading with HIP, CUDA, and OpenCL.

Some sources to support OpenMP target offload on AMD GPUs have not yet been merged into the upstream LLVM trunk. However all sources used by AOMP are available in AOMP repositories. One of those repositories is a mirror of the LLVM monorepo llvm-project with a set of commits applied to a stable LLVM release branch.

The bin directory of this repository contains a README.md and build scripts needed to download, build, and install AOMP from source. In addition to the mirrored LLVM project repository, AOMP uses a number of open-source ROCm components. The build scripts will download, build, and install all components needed for AOMP. However, we recommend that you install the latest release of the debian or rpm package for AOMP described in the install page.
