Struct GreenContext 

pub struct GreenContext { /* private fields */ }

A green context — an SM-partitioned CUDA context. Drops destroy the green context (does not affect the parent device context).

Implementations

impl GreenContext

pub fn from_resource(device: &Device, resource: CUdevResource) -> Result<Self>

Create a green context on device from a single resource (e.g. an SM partition produced by sm_resource_split_by_count).

pub fn as_ctx_raw(&self) -> Result<CUcontext>

Convert this green context into a regular CUcontext handle that can be set as current or passed to other APIs.

pub fn sm_resource(&self) -> Result<CUdevSmResource>

Fetch the SM resource the green context was created with.

pub fn create_stream_raw(&self, flags: u32, priority: i32) -> Result<CUstream>

Create a stream that only runs work on this green context’s SMs. Returns the raw CUstream — baracuda’s crate::Stream requires a full Context, so we return the raw handle for now.

pub unsafe fn from_raw(handle: CUgreenCtx) -> Self

Wrap a raw green-context handle — see GreenContext::from_resource for the normal constructor.

Safety

The caller guarantees handle is a valid CUgreenCtx that baracuda may take ownership of (destroyed on drop).

pub fn into_raw(self) -> CUgreenCtx

Consume the green context and return its raw handle without destroying it. The caller takes over the destroy responsibility.

pub fn as_raw(&self) -> CUgreenCtx
