Struct StreamPool

Source

pub struct StreamPool;

Expand description

Public interface for the CUDA stream pool.

Implementations§

Source §

impl StreamPool

Source

pub fn get_stream( ctx: &Arc<CudaContext>, device_ordinal: usize, ) -> GpuResult<Arc<CudaStream>>

Get a stream for the given device, round-robin across the pool.

On first call for a device ordinal, lazily creates [STREAMS_PER_DEVICE] non-blocking streams from the device’s CUDA context.

§Arguments

ctx — The CUDA context for the target device. Must match the ordinal (callers are responsible for passing the correct context).
device_ordinal — The GPU device index (0-based).

§Errors

Returns GpuError::InvalidDevice if device_ordinal >= MAX_DEVICES.
Returns a CUDA driver error if stream creation fails.

Source

pub fn pool_size(device_ordinal: usize) -> usize

Return the number of streams currently in the pool for a device. Returns 0 if the device has not been initialized yet.
