[Haskell-cafe] Parallel Haskell on an M2 Mac

[Bryan Richter]

I'd also be curious to know if you can somehow distinguish the types of
cores from each other, but otherwise all the usual parallel stuff should
work on Arm-based Macs as it works on other platforms supported by GHC. The
book described at https://simonmar.github.io/pages/pcph.html is still the
best source for learning about parallel Haskell.
