I'd like to thank Dalibor for making a very nice patch for the
problems with the GMP libraries in Kaffe on x86_64. Kaffe can use the
GMP libraries for BigInteger work, (with the -Xnative-big-math flag at
runtime) and it makes Kaffe quite spectactularly faster when working
with very large integers.
For example, to calculate the value of a large Mersenne prime,
2^20996011 - 1, and format that in base 10, here are the timings:
Kaffe: 16.72 seconds
Sun JVM 1.5.0: 18301.30 seconds (that's just over 5 hours.)
Nice! Both of these are on an Athlon 64 "3400+" (real clock speed
2200 MHz). While the Sun JVM is faster for many things (Kaffe is
interpreted on the x86_64,) this is a real selling point for large
numerical work.
Thanks to all who made this possible!
