primesieve 7.6 freeware

primesieve is written in portable C++, its speed is mainly due to the segmentation of the sieve of Eratosthenes which prevents cache misses when crossing-off multiples in the sieve array and the use of a bit array instead of the more widely used byte (boolean) array.

7.2 Nov 8, 2018 New Release primesieve-7.2 features a new algorithm for medium sieving primes that improves the CPU's branch prediction rate by sorting the sieving primes (before using them). On AMD EPYC CPUs I have measured a speedup of up to 20% and on Intel Skylake CPUs I have measured a speedup of up to 10%. Ever since primesieve was created in 2010 its algorithm for medium sieving primes has been slower than yafu's algorithm for medium sieving primes. This performance issue has now been fixed!
6.2 Dec 7, 2017 New Release This is a minor new release which fixes 2 bugs and improves
the primesieve GUI appThe API and ABI are backwards
compatible.
pmath.hpp: Fix integer overflow.
