python_vali.CudaStreamEvent

class python_vali.CudaStreamEvent

CUDA stream synchronization event

__init__(self: python_vali._python_vali.CudaStreamEvent, stream: int, gpu_id: int) → None

Create a new CUDA stream event.

Initializes a CUDA event for synchronizing operations on a specific CUDA stream and GPU.

Parameters:

• stream (int) – CUDA stream handle to associate with the event

• gpu_id (int) – GPU device ID to use

Methods

Record(self)	Record the current state of the CUDA stream.
Wait(self)	Wait for the recorded event to complete.
__init__(self, stream, gpu_id)	Create a new CUDA stream event.

Record(self: python_vali._python_vali.CudaStreamEvent) → None

Record the current state of the CUDA stream.

Creates a synchronization point in the CUDA stream. Equivalent to cuEventRecord in the CUDA API.

Note:

This operation is asynchronous and returns immediately

Wait(self: python_vali._python_vali.CudaStreamEvent) → None

Wait for the recorded event to complete.

Blocks until all operations in the CUDA stream up to the recorded event have completed. Equivalent to cuEventSynchronize in the CUDA API.

Note:

This operation is synchronous and will block until completion
