Little advice and tidbits are creeping out of Simon's head.
Is it time for a parallel performance wiki, where every question that becomes an FAQ gets documented live?
http://haskell.org/haskellwiki/Performance/Parallel
Maybe put details on the wiki so we can grow a large FAQ to capture this "oral tradition".
Absolutely. One reservation I have is that advice is likely to go out of date quite quickly; for example I'm planning to change the RTS options again before we release 6.12.1 to improve the default behaviour. Another reservation I have is that it's very difficult to pin down techniques that work consistently over different OSs and hardware. The best we can do is to document the techniques we know about, and advise people to try a variety of things to see which works best. Even that would be better than nothing, of course. Does anyone feel able to make a start setting up a wiki tree for parallel performance? I'd be more than happy to contribute and review content. Cheers, Simon
