Re: [Haskell-cafe] Parallel Haskell on an M2 Mac

Thanks, I'll check out the book. On Fri, Jan 19, 2024 at 4:47 AM Bryan Richter wrote:

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.

I don't know a lot about parallel Haskell, so I'm wondering in general terms how that would work with my M2 Mac. I have a search task that's easily run in parallel. For example, I might map a function over a list, and each item's evaluation can run in parallel. On the M2 MacBook I have, there are 4 efficiency cores with 1 thread each, and 8 performance cores with 2 threads each. Is it fairly easy to use parallel Haskell to spread the task over these 20 possible threads? By any chance could I limit it to using the performance cores if that helps the speed?
