Request: Open-CL / Vulkan / Metal support

[guymarshall]

Is your feature request related to a problem? Please describe.
I have an AMD GPU so I cannot take advantage of the CUDA running.

Describe the solution you'd like
I would love either an Open-CL or a Vulkan running mode (or both) if possible.

Describe alternatives you've considered
I have tried compiling to CUDA and then running a translation layer to Open-CL but the performance isn't what I expected.

Additional context
None.

We do plan porting to other platforms soon. We just want to first have one very solid implementation and CUDA happened to be the best/easiest to do it first.

No worries! Very impressive project, I am looking forward to using it in the future.

Will it be possible to run with zluda? https://github.com/vosen/ZLUDA (CUDA on AMD GPUs)

[joshuarossi]

hoping for metal support (it seemed like the cpu benchmarks were already on mac)

I think you mean AMD ROCM. ROCM is AMD's alternative to CUDA for nvidia. vulkan is for older GPUs. so finally it should look like
bend run-ro <file.hvm> # uses the ROCM interpreter (massively parallel)

You may be mistaken- Vulkan as a standard was released 8 years ago, and modern drivers only coming out in 2019 or later. (https://en.wikipedia.org/wiki/Vulkan)

On ROCm, it is not what we want. ROCm is a software stack specifically for AMD Graphics cards. CUDA, on the other hand is not a software stack. AMD's equivalent to Nvidia's CUDA is indeed OpenCL, or alternatively Vulkan. Vulkan specializes in graphics, where OpenCL is more general.

In any case fwiw OpenCL support would be appreciated, as it also would have the benefit of supporting intel GPUs.

If that is the case, I recommend reading the documentation of HIP Porting Guide as you write your CUDA. Main difference is to account for possible warp size of 64 instead of always assuming 32 and you are almost good to go with ROCm support

Vulkan would be great, in my experience Vulkan and ROCm are about the same actually and Vulkan has much broader support. I think it's the future personally once someone writes a nice wrapper around it that takes the role of CUDA or ROCm instead of being more generalized, I am not sure if it is the case with Vulkan vs CUDA I'd like to know honestly same with Vulkan and OpenVINO or whatever it is. But if Vulkan is so good at least on AMD, seems like no brainier just to implement that, not sure what the benefits of ROCm would be other than ease of development perhaps please correct me but seems to be my perspective as a user
