The WG is not focused on promoting or developing "standard" frameworks.

Instead, we want to provide basic and reliable support of the feature and inspire the community to start using it.

This WG is only about CUDA support - other GPGPU targets are out-of-scope. Our focus is on making the current CUDA target more reliable. Everything that goes beyond that (e.g. higher-level CUDA libraries, CUDA frameworks, etc.) is also out-of-scope.

## What is your long-term vision?

47
50
Having a reliable and safe CUDA development experience is our ultimate goal.
48
-
This should include:
49
-
50
-
* Getting `nvptx64-nvidia-cuda` to a [Tier 2](https://forge.rust-lang.org/platform-support.html) support state.
51
-
* Test infrastructure on a real hardware and running the tests during Rust CI process.
52
-
* Rich documentation, references, tutorials and examples.
53
-
* A broad set of new compile errors, warnings and lints for SIMT execution model to avoid pitfalls and ensure code soundness.
51
+
To get there, first of all, we will need to achieve all milestones in our [Roadmap].

## How do you expect the relationship to the project be?
56
54
57
-
The WG will be responsible for CUDA related issues and user requests.
58
-
This includes [already reported issues](https://github.com/rust-lang/rust/issues?q=is%3Aopen+is%3Aissue+label%3AO-NVPTX) and those that will be opened due to the work made by the WG.
59
-
An important aspect is that the WG will take care of the state of the `rust-ptx-linker` and will do its best to avoid blocking someone else's work (like it, unfortunately, happened in [rust#59752](https://github.com/rust-lang/rust/pull/59752)).
55
+
The Working Group is mainly going to create various RFCs and send PRs to Rust components.
56
+
57
+
An important aspect of the WG is active participation in discussions related to the NVPTX target and involved tools.

+
This also includes [already reported issues](https://github.com/rust-lang/rust/issues?q=is%3Aopen+is%3Aissue+label%3AO-NVPTX) and those that will be opened due to the work made by the WG.

### How do you want to establish accountability?

-
For that purpose, we will publish an agenda and made decisions from our meetings.
64
-
Once we achieve important milestones we plan to make public announces.
62
+
Currently, as an unofficial WG, we work completely in the open and we intend to go on in the same way.
63
+
Most of discussions happen either in out github issues, or in our public [Zulip], so that they be read by anyone.
64
+
65

Once we will start having regular meetings, we would publish agenda and summary.

## Which other WGs do you expect to have close contact with?

69
We would like to cooperate with *Language Team* in discussions about safety in SIMT code.

70
Additionally, it would be very important to discuss with *Infra team* a strategy of reliable deployment of `rust-ptx-linker` (likely as a `rustup` component).

## What are your short-term goals?
74
75
75
-
Mainly, short-term goals are about evaluating and discussing how can we achieve long-term goals:
76
-
77
-
* Make a poll about community experiences and use cases for CUDA.
78
-
* Deploy the `rust-ptx-linker` as a `rustup` component.
79
-
* Collect soundness and safety issues that can happen in SIMT execution model.
80
-
* Decide testing approach on a real hardware.
76
+
Mainly, short-term goals are defined in our [Roadmap] for an MVP.
77
+
Additionally, we plan to make a poll about use cases, expectations, and community awareness that it is already possible to experiment with CUDA on Nightly Rust today.
