Hello,
Where there were no entries to the http://shootout.alioth.debian.org/benchmark.php?test=chameneos&lang=all benchmark, there are now two. The one by Josh Goldfoot is already posted, the one Einar Karttunen and I optimized has been submitted and will run faster/smaller. Our code is at http://haskell.org/hawiki/ChameneosEntry
Now for improving the fasta benchmark, http://shootout.alioth.debian.org/benchmark.php?test=fasta&lang=all , which currently has a space leak in the Haskell entry.
A non-leaking version which has been optimized to run 3.5 times faster is now up at http://haskell.org/hawiki/FastaEntra (ooops..my spelling mistake).
It could still be made to run about 3 times faster, if the other languages are any guide. Anyone want to help polish this one?
Also, two other existing entries have space leaks, as can be seen at http://shootout.alioth.debian.org/benchmark.php?test=all&lang=ghc&lang2=ghc
And finially, the haskel entry for http://shootout.alioth.debian.org/benchmark.php?test=fannkuch&lang=all is currently the *slowest* entry out of 28 languages. It is 813x slower than the c-code, 500x slower than OCaml. Should be easy to make it faster...
While the implementation is far from "nice" it still finishes with N=9 (which, AFAICT, is what the benchmark is run with) in a fraction of a second on my machine (and not anywhere near 51s as in the benchmark)... I have a 2.6 Ghz P4... I was going to rewrite it using mutable STArrays for a pure version that's still fast but i sorta feel like I lost the motivation now that it turns out the existing implementation, though ugly, performs somewhat okay... /S -- Sebastian Sylvan +46(0)736-818655 UIN: 44640862
