Descriptive Data: (report abuse)

Genefer is a suite of programs for performing Probable Primality tests of (and as of 2016, primality proofs for) Generalized Fermat numbers. Highly optimised implementations of a specific transform are available for x86 CPU and for GPU supporting OpenCL.

Genefer has been extensively used by PrimeGrid computing project.

Genefer was originally developed by Yves Gallot in 2001 and was further improved by David Underbakke and Mark Rodenkirch.

The current version includes contributions from a number of developers, and has been open-source since 2011. Genefer is released under the MIT license.
