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 WebJan 27, 2024 · I can successfully capture the CUDAGraph and replay.
