PrimeGrid: January's PRPNet Challenge Project on GFN

[RSS]

Pierre de Fermat (1601-1665) is often called the "Prince of Amateurs." It is in his honor that the first PRPNet Challenge of 2011 is on the Generalized Fermat Number (GFN) Prime Search. A 3 day Challenge is being offered starting 12 January 2011 00:00 UTC on PrimeGrid's PRPNet. NOTE: PrimeGrid's BOINC Challenge series doesn't start until 3 February 2011.With the breakthrough of porting Genefer 2.2.0 to the GPU (CUDA), the search has become much more attractive. Testing times for the higher N's have been drastically reduced. NOTE: GPU app requires double precision support. Come be the first at PrimeGrid to report a Top 5000 prime found by a GPU.For more information, please see this forum thread (http://www.primegrid.com/forum_thread.php?id=3004&nowrap=true#30661).
