Hi guys, I'm optimizing a little benchmark called pnpoly, and I was wondering what is the proper way of hinting the compiler for types. In certain cases Clojure accepts for example loop [#^Integer c 0] and in others loop [c (int 0)] - I'm really trying to hint the compiler as best as I can.
I'm synced to the latest SVN version (1162), and in the same source code, it seems like loop[#^Integer c 0] works for some cases, and not for others. Here is the code in question: http://paste.lisp.org/display/75370 Also please note, what I'm doing wrong in it, what could be achieved more. My next step is to parallelize it, and compare again. So on my machine Clojure gives this result: (-600000 is okay, I was testing which one is better bit-not or subtracting 1 from the number). ; SLIME 2009-02-07 user> (time (pnpoly/pnpolytest)) "Elapsed time: 16075.309949 msecs" -6000000 C version is about 0.8s, Lispworks 1.3s, other Common Lisps (SBCL, CMUCL) about 2.0s ABCL: 6sec (using Java 1.6_10 -server, much like what I'm using for clojure). 16seconds it's not really that bad, considering I won't be using Clojure for heavy math code, but still wanted to see what I can do more with it. For example the same example in Python, Ruby or Perl runs at least for 200s (same with CLISP, haven't tried ECL or GCL).
