NVIDIA CUDA Library: cudaEventRecord

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. WebCUDA programming involves running code on two different platforms concurrently: a host system with one or more CPUs and one or more CUDA-enabled NVIDIA GPU devices.

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. I don’t think that you can change the behavior with OpenCL though. WebFeb 28, 2024 · CUDLA_CUDA_DLA - In this mode, ...

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.

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: http://man.hubwiz.com/docset/PyTorch.docset/Contents/Resources/Documents/_modules/torch/cuda/streams.html
