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. WebThe Cora dataset is a citation graph where nodes represent machine learning papers and edges represent citations between pairs of papers. The task involved is document classification where the goal is to categorize each paper into one of 7 categories. In other words, this is a multi-class classification problem with 7 classes. Graph
