You'll need RAM to get many digits.
1.6 G decimals in 20 hours on a machine with 16G RAM, running x86_64 Fedora 12.
Really, I'm curious, is there any real-world problem where anyone would actually *need* pi to a G decimal places?
Is there a *need* to climb Mount Everest ?
Actually, I had a machine with a RAM failure a couple of years ago.
It took days for Memtest86+ to find this error. The FFT code above (the same was used in Seti@Home) made the error show up within a few hours.

Or maybe there are still people who believe pi is rational rather than transcendent, and look for a cyclic repeat pattern in the decimals? ;-)
