Every time Simon responds on questions of parallelism and the GHC runtime, I learn something. That indicates to me that we've got a 'bus error' situation with how to effectively use the smp runtime.
Simon: time for a multicore FAQ wiki page to gather this knowledge, like we did for the performance tips? Somewhere to paste these insights?
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? Cheers, Johan
