[STF] Implement kernel chains in the graph backend without child graphs #3707

caugonnet · 2025-02-06T08:59:12Z

The implementation of kernel chains currently relies on child graphs, which is not the most efficient way to do this.

Otherwise, we need to create the child graph, fill it, then add the child graph which copies the nodes into the actual graph, and finally destroy the child graph. Instead we now have a vector of nodes, and simply add dependencies on the first and last nodes.
