TwinGen is a program to rapidly presieve a set of
candidates of the form
k . 2n +/-1 and remove
those candidates which are composite.
TwinGenX is a new 64 bit specialized sieve with many new
features and speed improvements including multiple n range,
multiple core support, multiple concurrent math modes, and
multiple density sieves.
