P-1 Error...

Xyzzy · 2003-12-14, 07:14

I just got a *pile* of these errors while working on some P-1 testing...

Code:

UID: Team_Prime_Rib/Xyzzy, Mxxxxxxx completed P-1, B1=10000, WZ1: 4C513C3F
P-1 found a factor in stage #1, B1=10000.
ERROR: Factor doesn't divide N!

I do have b1 and b2 set to 10000 for this run... (I only want to run stage 1!) What could be the problem?

I got a similar error when I was doing ECM factoring in January 2002. For me it happened just when the client was switching from day-time memory settings to night-time.

Code:

[Wed Jan 16 17:30:20 2002] 
ECM found a factor in curve #19, stage #2 
Sigma=5376994974570694, B1=11000000, B2=1100000000. 
ERROR: Factor doesn't divide N!

I got a similar error once, seems like it happened after switching from night-time to day-time memory settings. Machine was a lot overclocked that days though...
