Subject: OCaml image blending performance
Date: Wed, 6 Feb 2008 22:29:05 +0200 [thread overview]
Message-ID: <854c25eb0802061229o34a6155dncca9d8492cfe6932@mail.gmail.com> (raw)
Hi,
I was writing some image blending operations to get to grips with OCaml,
and wrote the same code in C as well. Asking (and receiving) advice for
optimizing the code on freenode #ocaml, I was told to post the code here
as it might be an interesting compiler test.
The C and Caml versions don't produce the same results, but should
have the same amount of computation (don't take my word for it though,
I don't know why the results differ.)
The source files are:
http://glimr.rubyforge.org/cake/blend.ml
http://glimr.rubyforge.org/cake/blend2.ml
http://glimr.rubyforge.org/cake/blend.c
Or as a tarball:
wget http://glimr.rubyforge.org/cake/blend_test.tar.gz
tar zxf blend_test.tar.gz
cd blend_test
./build.sh
cblend
real 0m1.466s
user 0m1.456s
sys 0m0.008s
blend
real 0m5.463s
user 0m5.456s
sys 0m0.012s
blend2
real 0m3.423s
user 0m3.404s
sys 0m0.012s
Use them as you wish.
