I’m trying to find a way of detecting async event without using host CPU’s polling. In NVIDIA CUDA GPU Computing SDK, there is AsyncAPI project (Please see below.) As you can see, the last part is CPU polling to detect the recording of the event. Is there any more efficient way to associate async event with an event handler or callback …

While NVIDIA GPUs are … 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 underlying CUDA events are lazily initialized when the event is first recorded or exported to another process. After creation, only streams on the same device may record the event.

WebJul 18, 2016 · Basically, you would record an event into each stream, after the kernel2-5 launches, and you would put a cudaStreamWaitEvent call, one for each of the 4 events, prior to the launch of kernel6. Like so:

Web( cudaEvent_t event ) Wait until the completion of all device work preceding the most recent call to cudaEventRecord () (in the appropriate compute streams, as specified by the arguments to cudaEventRecord () ).
