Count the number of primes
primecount is a command-line program and C/C++ library that counts the primes below an integer x ≤ 10^31 using highly optimized implementations of the combinatorial prime counting algorithms.

- Update to primecount-7.0 (API & ABI are backwards compatible). - AC.cpp: New algorithm with improved scaling. - AC_libdivide.cpp: New algorithm with improved scaling. - B.cpp: Improved scaling due to independent threads. - P2.cpp: Improved scaling due to independent threads. - LoadBalancerAC.cpp: New thread scheduler for AC algorithm. - LoadBalancerS2.cpp: Improve load balancing of S2_hard & D. - LoadBalancerP2.cpp: Rewritten, now similar to other load balancers. - SegmentedPiTable.cpp: Decrease size to x^(1/4). - util.cpp: Improve scaling using larger default alpha_z = 2. - imath.hpp: Optimize ilog2() & next_power_of_2() using __builtin_clzll().
