Subject: PARI/gp wins my Riemann zeta speed contest, so far
I had done my own Riemann zeta computations with Bernoulli numbers,
computing in days a few 10,000 (say 55,000) decimals of
the imaginary part of the first non-trivial zero
1/2 + i*14.13... using PARI-gp.
This time, I used PARI-gp's own zeta(.):
Sun Jan 20 03:36:28 EST 2013
Sun Jan 20 07:10:17 EST 2013
// 20,000 decimals precision
// t is with 1/10^400 of first non-trivial zero.
3 hours and 34 minutes for 20017 significant digits
near 1/2 + i*14.134725141734693790457251983562470270784257
realprecision = 20017 significant digits (20000 digits displayed)

On PARI-gp, I'm trying to get the readline library included.
That means backspace reprints the previous query, etc.
