Comparison of MPFR with Other Software
Updated for MPFR 2001 with
GMP 3.1.1.
32-bit machine
The following tables give the cpu time in milliseconds spent by
several systems or libraries for different operations, at different
precisions. These timings were obtained on a 400Mhz Xeon
(alexandre.medicis.polytechnique.fr) running Linux (libraries were
compiled with gcc 2.95.2 with option -O2). Thanks to the
Médicis center for
providing a machine with all those systems installed on it.

64-bit machine
The following timings were obtained, with the stimulation and help
of Bruno Salvy, on a 500Mhz Compaq XP/1000 (aka Alpha EV6) with gcc
2.95.2 under OSF/1 4.0 with 640MB of main memory
(leon1.medicis.polytechnique.fr).
