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. aspek kata https://urlocks.com
