I don’t see irony there. We’re locked into CUDA due to past decisions. And in new decisions we don’t want to repeat that mistake.
replyCUDA won because AMD and Intel made a mess out of OpenCL, and Khronos had no vision to support anything beyond C99 dialect until it was too late.
replyDoesn't matter if it was closed, when the alternatives were much worse.
Plus NVIDIA clocked that it was also the developer library ecosystem and even now there just aren’t equivalents. The AMD rocFFT library wasn’t even complete compared to FFTW until very recently and cuFFT did that more than a decade ago
replySYCL is the de facto successor to OpenCL that supports higher level languages. So the vision was and is there.
replyAs mentioned, Khronos only changed their mind when it was too late.
replyI can also recite the whole story, the missteps in OpenCL 2. , OpenCL C++, the OpenCL 3.0 reboot, how SYCL came to, CodePlay only proper available implementation, Intel acquisition of CodePlay and everything else.
