AMD has released AOMP 17.0-1 as the newest version of this open-source compiler focused on providing the latest OpenMP offloading support for Radeon and Instinct accelerator products.

AOMP is a set of patches carried atop the latest upstream LLVM/Clang state. AMD engineers continue working on upstreaming their various improvements to LLVM while for those wanting the leading-edge, best support have AOMP to leverage the best OpenMP device capabilities right now.

AOMP 17.0-1 is based on the state of upstream LLVM/Clang from earlier this month and is built with AMD's ROCm 5.4.4 sources. Notable with this update is switching over to its next-gen plug-in by default that in turn should yield significant OpenMP performance improvements.
