GPUJPEG with Vulkan

[MartinPulec]

Hi @wolfviking0,

thanks, I didn't know about that vuda, but as you mentioned, it would also need to convert the shaders to something that is compilable to SPIR-V (assuming that OpenCL would work).

Although it would be nice to do, I am afraid that I cannot promise anything now, it is mostly thing of priorities since this requires higher amount of work than small.

Anyways, what is exactly the point of running it with Vulkan? Support for cards other then NVIDIA? (or platform, namely mac?)

Yes for Mac and iOS but not only, I am also thinking for Android.

Thanks for the info. But as I already noted, there there will probably not be enough development capacity for that in near future.

I've also a bit searched and there are projects (also here) strive to compile also CUDA kernels to something more generic but I am not sure how much effort would it require to convert to SPIR-V, looks like more than one step would be required. Perhaps OpenCL could be also considered as a conservative intermediate?

I have to admit, that from my point of view there is now currently an explosion of (compute) APIs that I don't know and it is a pity that CUDA toolkit doesn't compile/transpile to anything else (but it a bit understandable).

hipcl was integrated into chip-spv which converts HIP to SPIR-V backends like OpenCL and Level Zero. So, in theory, if you've already went with HIP, it would be just a compile away. Well, in theory... :D
