primesieve x64 7.7 freeware

primesieve x64 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. ...

5.0 Jan 27, 2014 New Release primesieve-5.0 is a major new release that makes using the primesieve
library much more convenient. primesieve now includes C bindings for
all of its functions so that it can easily be used in languages other
than C++. I moved primesieve's build system to GNU Autotools and
Libtool which is more reliable than the hand written Makefile I used
primesieve-5.0 features a new API completely written from scratch that
is easier to use and that will not break binary compatibility with
every new release. The new API is not backwards compatible but porting
your code to the new API should be done quickly.
I bought a domain for primesieve and moved primesieve's repository
from Google Code (SVN) to GitHub (git)
Other changes:
New primesieve::iterator class that provides next_prime() and previous_prime() methods.
ParallelPrimeSieve now uses multi-threading by default, it does not care about arithmetic order anymore.
