primesieve 7.2 freeware

New Version

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!
