A good PC hardware for CLN ?
Hi ! I used CLN lib on linux debian Woody and try now libcln3 on debian Sarge ( on a Athlon T-Bird 1GHz 400Mo RAM ). I think to buy a more recent PC computer. What kind of PC for CLN - processor INTEL or AMD - to execute speedly integer computations ? Is motherboard worthy ? Thank you for your help. Fabrice

I invariably recommend AMD64 these days (socket 939). My off the shelf 2.2GHz system is on par with a 3.6GHz intel equivalent (EMT64(?), ex-pen-sive!) for the interesting stuff. System is 2-3.5 times faster than Athlon at same clock. Memory throughput is a dream. The timings given (by Granlund) are a true eye opener: http://swox.com/doc/x86-timing.pdf Today's intel 64bit cores are a lousy hack at best. Alternative architectures (PPC) might be fine but are surely much more expensive. -- p=2^q-1 prime <== q>2, cosh(2^(q-2)*log(2+sqrt(3)))%p=0 Life is hard and then you die.

Even without x86-64 Assembler code, the use of 64 bit Digits gives an very impressive performance gain. If you buy such a machine, make sure to run int in 64 bit userland if arbitrary precision arithmetic is important for what you're doing. Regards -richy. -- Richard B.

I am deleting your message because the date is set far in advance, in an apparent effort to make your email stand out over all others. Byron Hale Fabrice Marchant wrote:
