Thanks very much for the timings, Victor.
Just out of interest, could you try the pydigits script with the
+optimizations patch on 32-bit?
As mentioned above, there's a significant (for 30-bit digits) problem
with x_divrem: the inner loop does a 32 x 64-bit multiply when it
should be doing a 32 x 32-bit multiply (the variable q is declared as
twodigits, but always fits into a digit). This is fixed in the
+optimizations patch, and pi_digits is heavy on the divisions, so I
wonder whether this might make a difference. |
