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: Webuse_cuda - whether to measure execution time of CUDA kernels. Note: when using CUDA, profiler also shows the runtime CUDA events occuring on the host. Let’s see how we can use profiler to analyze the execution time: with profile(activities=[ProfilerActivity.CPU], record_shapes=True) as prof: with record_function("model_inference"): model(inputs)
WebAug 19, 2010 · Hi. 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 … WebCUDA events are synchronization markers that can be used to monitor the device’s progress, to accurately measure timing, and to synchronize CUDA streams.
