## Describe the changes
This PR fixes an issue when `RunOnDevice` is called for multi-gpu while
other goroutines calling device operations are run outside of
`RunOnDevice`. The issue comes from setting a device other than the
default device (device 0) on a host thread within `RunOnDevice` and not
unsetting that host threads device when `RunOnDevice` finishes.
When `RunOnDevice` locks a host thread to ensure that all other calls in
the go routine are on the same device, it never unsets that thread’s
device. Once the thread is unlocked, other go routines can get scheduled
to it but it still has the device set to whatever it was before while it
was locked so its possible that the following sequence happens:
1. NTT domain is initialized on thread 2 via a goroutine on device 0
2. MSM multiGPU test runs and is locked on thread 3 setting its device
to 1
3. Other tests run concurrently on threads other than 3 (since it is
locked)
4. MSM multiGPU test finishes and release thread 3 back to the pool but
its device is still 1
5. NTT test runs and is assigned to thread 3 --> this will fail because
the thread’s device wasn’t released back
We really only want to set a thread's device while the thread is locked.
But once we unlock a thread, it’s device should return to whatever it
was set at originally. In theory, it should always be 0 if `SetDevice`
is never used outside of `RunOnDevice` - which it shouldn’t be in most
situations
## Describe the changes
This PR:
- Moves common crate attributes to the workspace Cargo.toml.
- Adds a manual release flow for bumping, tagging, and draft release
This PR is a compilation of small improvements
- Lock bindgen version for `icicle-cuda-runtime`
- Add an error message when trying to build on Mac (or any non
windows/linux machine)
- Add documentation and template files for adding new curve
- Add documentation on _params.cuh contents
- Add the script to bump all the rust crates versions to the same
version
Resolves#313
## Describe the changes
This PR adds the use of setup-go in the CI to ensure that `go` is
installed properly and caches dependencies and build outputs by default
Updates the CI to:
- run per supported language
- conditional run logic
- pipelined jobs for failing fast
- additional parallelization
- run golang build on windows
- reuse the check-changed-files workflow

- Make the curve config's omegas_count conditionally accessed when creating fields
- Remove the extern C function that returns a UDT containing non-POD types and replace it with a default_config function on the Rust bindings side
