Na compute je ROCm, kde treba davat pozor na jadro. APU a Polaris by mali fungovat s 4.17/4.18, Vegy este nie, tam bud pouzit ROCm fork, alebo si pockat kym sa to dostane upstream. ROCm vie HSA s nativnou ISA GCN, OpenCL (iba 1.2, nie 2) a pracuju na podpore na portovanie CUDA aplikacii do ROCm (HIP).
AMDKFD v 4.18 už podporuje Vega-u
