Interesting paper. The original concept is at http://people.csail.mit.edu/sanchez/papers/2018.hotpads.micr..., and the follow up paper the article is written about is https://people.csail.mit.edu/poantsai/papers/2019.zippads.as....

Afaict the gist of the hotpads paper is this:

Dump the existing way we organize processor caching, instead make it look like generational gc where objects can move between different caches, and pointers can be re-written to point to the new cache level that the pointee is in.
