[FEA] Can we support graph isomorphism algorithm

[Roy-Kid]

We want to use GPU to accelerate graph isomorphism, but it seems no implementation for nx.isomorphism.GraphMatcher. We hope to use this algorithm to accelerate the matching of force field parameters with protein residues, so that we can carry out a larger scale MD simulation. Is there any relevant implementation plan recently?

We don't currently have graph isomorphism on our roadmap. There are some recent papers on efficient GPU implementations that we can evaluate, I will add this to our list of things to prioritize.
