I have a machine that when my son played a certain kids game, it would mark a factoring assignment that was in a 64 bit or higher pass as complete immediately and return the result. I discovered it was because of a bad sound driver. I fixed that and reran the two exponents it prematurely ended. _ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

Mersenne: Factoring hiccup?
An odd thing happened today. I have version 21.4.1 on my laptop (a PIII-1000, but only turned on a few hours a day so that LL tests would take months) doing trial factoring. I ahppened to see the following in the screen display tonight: [Feb 13 01:44] Factoring M21632497 to 2^67 is 14.43% complete. [Feb 13 01:45] Factoring M21632497 to 2^67 is 14.46% complete. [Feb 13 01:46] Factoring M21632497 to 2^67 is 14.49% complete. [Feb 13 01:47] Factoring M21632497 to 2^67 is 14.52% complete. [Feb 13 01:48] Factoring M21632497 to 2^67 is 14.55% complete. [Feb 13 01:49] Factoring M21632497 to 2^67 is 16.14% complete. Strange. Do we know if this is just a minor glitch in the GUI, or if the factoring algorithm actually misses factors?
