Thank you, scatter-gather was the google term I was looking for, though I couldn't immediately find any architectures that implement a vector scatter-gather. Are you aware of any?

The Cray absolutely did. How else do you do sparse matrix multiply?

Not sure what could be a scalar scatter/gather, but NV and AMD GPUs do the vector one (you can read write n values from n offsets with a single instruction).
