Re: [Haskell-cafe] A tale of three shootout entries

Never mind. I screwed up the timings. The new haskell timings are still a huge improvement but they are: -0.169075164 -0.169031665 real 0m27.196s user 0m19.688s sys 0m0.163s On Nov 27, 2007 11:25 AM, Ryan Dickie wrote:

N-body is looking good. I am running and amd64 3000+ on ghc 6.8.1. The debian shootout is showing a huge gap between ghc 6.6 and g++ but I am not seeing that gap. One concern though is that the code doesn't look very "haskellish". So much pointer manip.

For the nbody c++ code I am getting: -0.169075164 -0.169031665

In some spare time over the holidays I cooked up three shootout entries, for Fasta, the Meteor Contest, and Reverse Complement. I

Yay!

First up is the meteor-contest entry.

http://shootout.alioth.debian.org/gp4/benchmark.php? test=meteor&lang=ghc&id=5

This is the clear win of the bunch, with significantly improved time thanks to its translation of the better algorithm from Clean.

Well done! Though looks like we'll have to follow the C++ implementation

to be really competitive.

Next is reverse-complement.

http://shootout.alioth.debian.org/gp4/benchmark.php ? test=revcomp&lang=ghc&id=3

Very good. I'm glad someone looked at that, since the old code was moderately naive (first bytestring effort).

Finally, there's fasta.

Yeah, we should do something better here. Hmm.

p.s. It looks like they've depreciated chameneos in favor of a new version, chameneos-redux. As this was one of the places Haskell really rocked the competition, it would probably be worth updating

Definitely. I note also we're beating Erlang on the new thread-ring benchmark too,

http://shootout.alioth.debian.org/gp4/benchmark.php?test=threadring&lang=all

the Haskell entry for the new benchmark. Also, the n-bodies benchmark seems like another that could be much improved.

Yeah, that's a hard one.
