Do you have a Linux box sitting idle? Your CPU cycles could help
crunch a distributed problem.
If you have a MHz+ Linux box sitting idle, we will custom-compile the
program for your iron (OS version and CPU) or furnish the source code
and you can compile and optimize it (No Microsoft! BillGates'
compilers do not support 80-bit long_double_precision). Toss in a
thousand points to help fill the gap and extend the red meteor.

Wintel works 40% slower than Linux. Post here, or contact Uncle Al at

Motivation: Einstein assumed everything falls identically in vacuum,
hence metric gravitation (General Relativity). Weitzenboek made no
such assumption, hence affine gravitation. While the maths are wildly
different, the predictions are exactly identical... except either
everything falls identically in vacuum or there is an exception.
Folks look at this stuff big time,

A possibly clever experiment in alpha-quartz

Bull. Amer. Phys. Soc. 49(2) 54 (2004)
is being fabricated in Wuhan, China as you read this. Full results
are expected by summer 2005. The submitted graph

has 711 points. Alas, diddle has amazing small scale structure,

so we are recrunching the analysis with a few more points,

17,200 points so far.
I'd like to fill the gap and extend the meteor. It's about 7
minutes/point in fast iron. Runtime/point increases as the square of
the radius. We can easily script 8-hour overnight runs. Another
10,000-50,000 points would help. The program eats 98+% of CPU cycles,
but uses no other machine resources aside from the text output files.
You can help crunch quartz, or we will shoot this System
Administrator. No, wait... You can help crunch quartz, or we will NOT
shoot this System Administrator. "8^>) If your iron is sitting there
bored or unused, we can give its life meaning. Post here, or contact

Thank you!
