fast & Nice

[Isaac Gouy-2]

See
http://shootout.alioth.debian.org/gp4/benchmark.php?test=spectralnorm&lang=all

But why is Nice memory use so much less than Java for
those programs?


Incidentally, there are still many benchmarks without
Nice programs

Wow, nice is the second fastest language around? ;-)

Is the implementation very close?

One possibility is that the JVM is started with different arguments. Another
is a subtle interaction with the garbage collector. Is this the case for most
benchmarks, or only this one?

Perhaps I should note that the Nice program is being run on jdk1.5.0_05
and nosed-ahead of the jdk1.5.0_05 program. ;-)

The method text is copy & paste from the Java program to Nice.

In Java they are non-static methods, in Nice they are package-level.

Java

Nice

The Nice program is in a jar file, the Java program isn't.
(A build & run log shown below each program source code listing.)

This one seems to be an exception (and in other cases the Nice and Java
programs may differ more).

best wishes, Isaac

On a similar vein to the Computer Language Shootout, I just
encountered a link to the "JVM Language Soko-Shootout" (
http://opal.cabochon.com/~stevey/sokoban/ ) ; an interesting site that
I haven't seen mentioned on this list before.

It compares nine different JVM-targetting languages by writing an
implementation of Sokoban in each, and gives the author's impressions
of writing in each language - rather than performance stastics.
Unfortunately it's incomplete, but it's interesting nonetheless.

Some complimentary quotes:

"Nice is a fascinating JVM language that's very different from most of
the other languages in the shootout... Overall, Nice was one of my
favorites, and I'd use it again... I can't believe Java doesn't have
more features from Nice! ... Daniel Bonniot over at INRIA is
(obviously) a very gifted programmer and computer scientist"

I found this via a link in the comments to Bruce Eckel's discussion of
Groovy at Artima -
http://www.artima.com/forums/flat.jsp?forum=106&thread=147353.

Cheers

Inigo
