Hi,
I am running into a weird out of memory issue. While running timeplot over
an input file having ~800 rows. From below provided info, seems like
machine has enough ram (1849MB).
Please let me know if anyone has pointers.

Aha!!! Now it's working. Just had to compile with -O2 :D :D
Now I'm over twice as fast for a list of 2 million! With better length
based analysis of how many buckets should be used, this number can be
improved.
You can feel free to use my code however you like. I've attached the final
version

Thanks for the advice. After taking most of it it is faster. But it is
still many times slower than it ought to be! This algorithm should be much
faster than simply sorting the list, and yet it is more than twice as slow!
One note, you said:

Dear Haskell Cafe,
I am working on a solver for Slitherlink puzzles in Haskell. Today I am
completely puzzled that a small change I made had a huge performance
impact. I thought the change to be merely cosmetic to make a function a
little more elegant and the code more readable. But this change s

Hi Jim,
Thanks for such a quick response.
Previously I've been able to install and use ghc and HP in ~/ without
problems. Is there any reason
why this couldn't be done with your justhub package?
As I've never tried this brute surgery on such a magnus opus before I'm
So I've been playing with the median problem today. Not sure why, but it
stuck in my head.

I've been using the hashing algorithm that I described last night, but it's
quite slow. I must be missing something obv

Thanks Henk!

The action on that HP ticket was to put a link here,
http://hackage.haskell.org/platform/linux.html, which should happen by the next
platform release.

Hi Manish,
Are you aware of the CentOS distro I am maintaining at justhub.org
/download? Even if you want to build your own installations it will probably
be useful for getting you going.
(It should soon appear on the Haskell Platform Linux page - or at least we
have a ticket for it!)
