AOMP is AMD's LLVM downstream focused on providing the latest OpenMP device offloading support to their hardware ahead of the relevant patches being upstreamed into LLVM itself. AOMP 18.0-1 is the latest version based in turn on LLVM 18 Git, with LLVM 18 stable expected in March .
The AOMP 18.0-1 compiler has re-based its sources against targeting the big ROCm 6.0 release that debuted in December. ROCm 6.0 provides Instinct MI300 series support, new AI capabilities, and more for this open-source GPU compute stack.
AOMP 18.0-1 also notably now defaults to the -O2 optimization level if no other optimization level is specified. Up to now AOMP would default to no compiler optimizations (-O0) if not specified so at least now it's using the sensible -O2 as the default behavior for better out-of-the-box performance.
AOMP 18.0-1 also contains build system enhancements to make it easier to compile this AMD OpenMP compiler from scratch, test infrastructure improvements, and various fixes.
The AOMP 18.0-1 sources as well as CentOS/RHEL, SUSE, and Ubuntu binaries are available via GitHub for those wanting to enjoy the latest AMD OpenMP device offloading support.
