After publishing this a few days ago, 2 things have happened.

First, it tuned out that StringZilla scales further to over 900 GigaCUPS around 1000-byte long inputs on Nvidia H100. Moreover, the same performance is obviously accessible on lower-end hardware as the algorithm is not memory bound, no HBM is needed.

Second, I’ve finally transitioned to Xeon 6 Granite Rapids nodes with 192 physical cores and 384 threads. On those, the Ice Lake+ kernels currently yield over 3 TeraCUPS, 3x the current Hopper kernels.

The most recent numbers are already in the repo: https://github.com/ashvardanian/StringWa.rs
