WebNov 11, 2024 · Hi Alan, I can't see the benefit in your example, and as I´ve understood the CUDAGraph purpose is to implement a "circuit" of kernels as an alternative of dynamic parallel processing. In the source of simpleCUDAGraphs sample it is much more clarify, but still I have not found a sufficiently instructive example. We can further improve performance by using a CUDA Graph to launch all the kernels within each iteration in a single operation. We introduce a graph as follows: The newly inserted code enables execution through use of a CUDA Graph. We have introduced two new objects: the graph of type cudaGraph_t … See more Consider a case where we have a sequence of short GPU kernels within each timestep: We are going to create a simple code which mimics this pattern. We will then use this to … See more We can use the above kernel to mimic each of the short kernels within a simulation timestep as follows: The above code snippet calls the kernel 20 times, each of 1,000 … See more It is nice to observe benefits of CUDA Graphs even in the above very simple demonstrative case (where most of the overhead was already being hidden through overlapping kernel launch and execution), but of … See more We can make a simple but very effective improvement on the above code, by moving the synchronization out of the innermost loop, such … See more

WebOct 11, 2024 · CUDA graphs are a new way to synthesize complex operations from multiple operations. With "stream capture", it appears that you can run a mix of operations, including CuBlas and similar library operations and capture them as a singe "meta-kernel". What's unclear to me is how the data flow works for these graphs.
