Re: [Haskell-cafe] Language Shootout reverse-complement benchmark

Inspired by this post I looked at the language shootout. There is one thing which strikes me: On http://shootout.alioth.debian.org/u64/performance.php?test=spectralnorm#about It sais for the spectralnorm benchmark that both Haskel GHC #4 and HaskellGHC produce "bad output". For GHC I connt see

On a similar note, there was no parallelized implementation for spectral-norm, even though Haskell had been doing rather well on the single-core benchmark. Heh. Louis Wasserman wasserman.lo...@gmail.com http://profiles.google.com/wasserman.louis On Tue, Jun 1, 2010 at 10:38 AM, Gwern Branwen w

I'm still trying to figure out what the point of the shootout really is. If there's no dedicated folks working with a language there, trying to make things run faster, a language will come out looking inefficient potentially. There's a lot of compile flags and optimizations that can make a differ

2010-06-01 Thread Louis Wasserman
Hey, I was looking at the reverse-complement benchmark on the Language Shootout, and among other things, I noticed that the Haskell implementation was using (filter (/= '\n')) on ByteStrings, and also using lists as queues. I had a few improvements which using -fasm seem to yield about a 19% impr
