Just for fun, I tried to run a FFT program from the IBM Ninja (Numerically Intensive Java) package. After implementing a few more native methods, it ran, but to my surprise it ran about as fast as under JDK 1.4 (with Sun's Hotspot VM). Not bad for totally unoptimized code
The cfft.java source that I ran can be viewed here, the resulting executable (in a zip) can be found here and I've updated the project snapshot. For the array package, follow the Ninja link.
I apologize for the lameness of this, but the comment spam was driving me nuts.
In order to be able to post a comment, you need to answer a simple question. Hopefully this question
is easy enough not to annoy serious commenters, but hard enough to keep the spammers away.
Anti-Spam Question: What method on java.lang.System returns an object's original hashcode (i.e. the
one that would be returned by java.lang.Object.hashCode() if it wasn't overridden)? (case is significant)
