%description

Primecount is a command-line program and C++ library that counts the

primes below an integer x<=10**31 using highly optimized implementations

of the combinatorial prime counting algorithms.

Primecount includes implementations of all important combinatorial prime

counting algorithms known up to this date all of which have been

parallelized using OpenMP.  Primecount contains the first ever open

source implementations of the Deleglise-Rivat algorithm and Xavier

Gourdon's algorithm (that works).  Primecount also features a novel load

balancer that is shared amongst all implementations and that scales up

to hundreds of CPU cores.  Primecount has already been used to compute

several world records e.g. pi(10**27)

(http://www.mersenneforum.org/showthread.php?t=20473) and

nth_prime(10**24) (https://oeis.org/A006988).
