Alioth k-nucleotide

Defect Major Open Unresolved Unassigned David Nolen Sat, 21 Jan 2012 13:05:24 -0600 Thu, 23 Feb 2012 22:46:37 -0600 1 1 <p>Have added my latest version of the k-nucleotide benchmark in the following repository:</p> <p><a href="https://github.com/mikera/test.benchmark/">https://github.com/mikera/test.benchmark/</a></p> <p>Please create a patch of your changes and add it to the ticket, thanks!</p> <p>If you add a patch, I can take a look at this tonight.</p> <p>Mike,<br/> I did pull down your repo and ran some tests.<br/> This version of k-nucleotide does run faster than the currently submitted version in alioth.<br/> However, we've got a ways to go to catch the faster Java implementations.</p> <p>I've added a few comments in your repo.<br/> Of note, the (set! <b>unchecked-math</b> true) directive at the top of files allows us to use inc, dec, etc directly without explicitly specifying unchecked-inc, etc.</p> <p><a href="http://shootout.alioth.debian.org/u64q/program.php?test=knucleotide&amp;lang=java&amp;id=9">http://shootout.alioth.debian.org/u64q/program.php?test=knucleotide&amp;lang=java&amp;id=9</a> is the fastest java version, but is a bit gnarly.<br/> <a href="http://shootout.alioth.debian.org/u64q/program.php?test=knucleotide&amp;lang=java&amp;id=2">http://shootout.alioth.debian.org/u64q/program.php?test=knucleotide&amp;lang=java&amp;id=2</a> is a little slower, but in the same order of magnitude for performance, and significantly more straightforward.</p> <p>You might check those out for some inspiration to boost the performance of clojure's knucleotide.<br/> Good luck and thanks for the help!</p> Global Rank
