I have a new dual-core Athlon 64 X2 and WinXP 64-bit edition with 
Mathematica 5.2. SingularValueDecomposition with a random 2000x2000 
matrix takes about 41 seconds to complete but the processor load stays 
around 50% all the time. It seems that we'll have to start getting some 
refund of the price of Mathematica.

Best regards,
Antti Penttilä
