The discovery was made by David Tomecko of the United States using an NVIDIA GeForce GTX 570 in an Intel Core i7 980 @ 3.33GHz system with 24GB RAM, running Windows 7 Ultimate. This GPU took about 55 minutes 24 seconds to probable prime (PRP) test with GenefCUDA. David is a member of the The Knights Who Say Ni! (http://www.primegrid.com/team_display.php?teamid=16) team.
