Greetings! Richard Fateman <[EMAIL PROTECTED]> writes:
I have another program that is about twice as fast as k. The code is much longer, and also produces an array of bits with 1 at the position of prime numbers up to n/2, but it uses code from commercial Macsyma. The mpz_fac_ui code may be faster in GMP 4.2. I am guessing your test used GMP 4.1.14 or so.
Good guess -- 4.1.4. Do you have specific reason to suspect improvements in 4.2? Yes, I found some GMP-related email saying that someone Paul Zimmermann, I think, put a better factorial in GMP, first available in 4.2. _______________________________________________ Gcl-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/gcl-devel
