IMHO, the question is not that we need code to run on CPUs and GPUs , we do need that, The question is whether the GPU seller has to control both sides. Until I buy a CPU from nvidia I want to keep some kind of independence.

When will we be able to use a future riscv-64 CPU with an nvidia GPU ? we will let the answer to nvidia ?

The question is not about running code on CPUs, or running code on GPUs. It's about running code on both CPUs and GPUs at the same time. It's about enabling the code on the CPU and the code on the GPU to seamlessly interoperate with each other, communicate with each other, move objects and data to and from each other.

Who do you expect to make that happen?

You can buy a CPU from NVIDIA, check out our Tegra systems. We also sell full systems, like DGX platforms, which use a 3rd party CPU.

Who else would answer this question?

Okay, you want to use <insert some future CPU> with our GPU.

Who is going to design and build the interconnect between the CPU and the GPU?

Who is going to provide the GPU driver?

The CPU manufacturer? Why would they do that? They don't make any money from selling NVIDIA products. Why should they invest effort in enabling that?

You can use this library to write code that runs on both risc-v and a GPU! You seem to be pretty confused about what this library is. It’s not exerting any control. It’s open source! It’s strictly optional, and it only allows developers to do something they actually want, to write code that will compile for any type of processor that a modern c++ compiler can target.

Again, I see what you mean. I am even against nvidia advising the developers to use such or such C++ library (be it GNU). It is not their role to do that. We need smarter and more shining GPUs from nvidia, not software.

I would say .... The hardware must be sold independently of the software ... but it is a bit too complex, I know.
