Cuda wait event

The stream stream will wait only for the completion of the most recent host call to cudaEventRecord() on event. Once this call has returned, any functions (including cudaEventRecord() and cudaEventDestroy()) may be called on event again, and the subsequent calls will not have any effect on stream. WebCUDA events are synchronization markers that can be used to monitor the device’s progress, to accurately measure timing, and to synchronize CUDA streams. The …

WebOperations inside each stream are serialized in the order they are created, but operations from different streams can execute concurrently in any relative order, unless explicit synchronization functions (such as synchronize () or wait_stream ()) are used. For example, the following code is incorrect: WebAug 19, 2011 · Busy wait loop is actually the default behavior under NVIDIA. Under CUDA you have an option to change the behavior into blocking synchronization or to wait on an interupt. The purpose of busy waiting is actually to get minimal latency in the responce.
