Description: I run something like t = time.time() loss = model(x) loss.backward() cost = time.time() - t but I got almost the same result with/without torch.cuda.synchronize(). I have called .cuda() for model.(the model is on gpu) There should be no gpu-cpu transfer(i.e. .cpu() or .gpu()) in …

WebNCCL kernels are blocking (waiting for data to arrive), and any CUDA operation can cause a device synchronization, meaning it will wait for all NCCL kernels to complete. This can quickly lead to deadlocks since NCCL operations perform CUDA calls themselves. WebMay 4, 2024 · Vertical Synchronization (VSync), helps create stability by synchronizing the image frame rate of your game or application with your display monitor refresh rate. If it's not synchronized, it can cause screen tearing, an effect that causes the image to look glitched or duplicated horizontally across the screen.
