I've looked through that paper a few times, and it's not clear that it's "powered by supercomputers". It used resources from supercomputing centers, but the referenced software appears to use either OpenMP or a GPU on standard hardware, and not a supercomputer. Assuming I read the paper carefully, either I have the wrong citation, or the author didn't read the paper carefully, or the author is exaggerating.
