A few weeks ago, during the weekly GHC meeting, Simon explained the
internals of the threading system to me. Among other things he
explained how many threads are run per core, how they are load
balanced and migrated between cores. I found it very enlightening.
Maybe, that could serve as a basis for a GHCThreadingInternals wiki
page. Is #ghc channel logged anywhere?
