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 …

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 … WebCUDA Events and Streams Students will learn to utilize CUDA events and streams in their programs, to allow for asynchronous data and control flows. This will allow more interactive and long-lasting software, including analytic user interfaces, near live-streaming video or financial feeds, and dynamic business processing systems.
