Shootout PiDigits program kinda sucks (and possibly so does GHC)
Feb 12th, 2009 by axman6

So I’ve been trying to see if I could speed up the pidigits program, and, well, failed. I’m not alone though, Stephen Blackheath and others have tried too, and no one’s managed to make things much, if at all faster. The main problem seems to be that GHC is allocating a lot of RAM, which must be related to the need for Integers. The current program uses up 500+MB by the time it finishes. Not good. So, I’m putting a call out to see if anyone else can either think of a better way to get the answer than the current entry, or any tips about reducing memory usage. If you come up with anything, I’d love to hear from you. Cheers, ~ Axman
