Maybe someday.

Only mention I've seen of ROCm on Windows10 as a possibility:

Planned support for OpenCL was announced last year: https://devblogs.microsoft.com/direc...x-heart-linux/. Also see: https://github.com/microsoft/WSL/issues/6372.

Thanks for the links tdulcet.
Sounds like mapping or emulation, inefficient, slow, to me. Not OpenCL native support, but a translation layer into DirectX. https://devblogs.microsoft.com/direc...rs-to-directx/ Perhaps better than nothing, wait and see, until whenever; no schedule given in the provided links, for the availability of the mapping layer, or for the required WSL support to follow.
I'm skeptical that MS will map a sufficient, compatible, and efficient subset of OpenCL to preserve gpuowl and mfakto performance close to that on native OpenCL drivers, at least in the initial years. MS generally operates by successive approximation over several major releases. My impression over nearly 40 years of use.

"initial support targeting OpenCL 1.2" probably means no 2.0 atomics used by Gpuowl since after ~v1.9. https://devblogs.microsoft.com/direc...rs-to-directx/

Perhaps Preda would consider someday splitting to two back ends again, this time OpenCL and DirectX https://mersenneforum.org/showpost.p...&postcount=429
