Following last week’s release of the LLVM/Clang-downstream AOCC 5.0 for optimized compiler support extended to Zen 5 CPUs, the GPU side of the house at AMD this week released AOMP 20.0-0 as their LLVM/Clang downstream focused on GPU device offloading.
AOMP remains the AMD-maintained LLVM/Clang downstream compiler focused on OpenMP API device offloading to Radeon GPUs and Instinct accelerators. AOMP pulls in all of the latest AMDGPU compiler back-end bits and associated device offload patches for what isn’t currently within the upstream LLVM repository. But unlike the AOCC compiler, AOMP is open-source. The AOMP developers also do a good job ensuring their patches do work their way upstream where relevant in a timely fashion.
AOMP continues to track LLVM Git and hence the version 20.0-0 to mark their first release since LLVM Git was bumped to version 20 development. AOMP 20.0-0 pulls in the latest ROCm 6.2.2 source code, AOMP now creates the relevant rocm/clang/clang++ configuration files, the gpurun utility now has multiple device support using the “-md” argument, updates to AOMP example code, and other updates.
AOMP 20.0-0 also adds in ROCm SMI and AMD SMI as AOMP components. Lastly the gfx90c, gfx1103, gfx1150, gfx1151, and gfx1152 AMD GPU targets are now enabled. GFX115* are for the RDNA 3.5 refresh parts and gfx1103 is for the Radeon 780M and gfx90c is for the AMD APUs with Vega graphics.
