Ooh that's interesting, do you have any leads or examples?

It's seen sometime even on multinode jobs. But it's definitely the exception to the rule, but it does happen. It's helped by the fact that each level of cache is approximately 10x faster, so fitting in a cache is a huge win. So running in ram on 1 node might be 20x slower than running in cache on 10 nodes.
