Are you talking about CUCALucas or Prime95? My reference is to the periodic time-outs which cause the card to be reset while running CL.

Prime95, and I was replying to Madpoo's "resulted in lots of re-doing using the safer method" line. This is P95-specific.

Updated factoring list
 
Here's an updated list of some exponents that could use extra TF.

First list: exponents that need triple-checking but could use extra TF beforehand:
[CODE]exponent TF WorkToDo
45486481 70 Factor=45486481,70,72
45962519 70 Factor=45962519,70,72
46328993 71 Factor=46328993,71,72
46706797 70 Factor=46706797,70,72
47041213 71 Factor=47041213,71,72
47562511 70 Factor=47562511,70,72
47725303 70 Factor=47725303,70,72
48074977 71 Factor=48074977,71,72
49964059 71 Factor=49964059,71,72
50500493 72 Factor=50500493,72,73
52823003 71 Factor=52823003,71,73
52825231 71 Factor=52825231,71,73
52870133 71 Factor=52870133,71,73
53146861 72 Factor=53146861,72,73
53320051 72 Factor=53320051,72,73
53692733 72 Factor=53692733,72,73[/CODE]

And this list of exponents with maybe a 50/50 chance of being done wrong the first time... might as well do extra TF before doing a DC:
[CODE]exponent TF WorkToDo
45501193 71 Factor=45501193,71,72
46373879 70 Factor=46373879,70,72
46654913 70 Factor=46654913,70,72
47139353 70 Factor=47139353,70,72
47697667 70 Factor=47697667,70,72
51060413 70 Factor=51060413,70,73
54649009 71 Factor=54649009,71,73
55270477 72 Factor=55270477,72,73
55280077 72 Factor=55280077,72,73[/CODE]

That's all of those for now.

Yeah, I read up on that a little. I haven't paid too much attention to how the FFT sizing at the beginning of a test correlated with how often it does the roundoff error thing. Sometimes it gave a roundoff error when it didn't do the FFT test first, so it wasn't near a threshold exactly.

Overall, while it happens enough that I notice, it's a smallish percent of the total so I don't worry about it too much. Now, if it were giving me bad results, that'd be a different story. As it is, with a 10 minute interval between save files, it doesn't have to roll back too far during the retest/reset, compared to when it was using the default of 30 minutes.

Therefore, I vote the next build of Prime95 changes the default to 10 minutes. at least. :smile: Or 5?

OK. Thanks. I'll try to keep track of that. I thought you might have been saying something about an unusual number of CuLu resets.

I think there was some cross-posting going on, as the current sequence makes your response logical. Oops! :smile:

I'll do the TF.

For 36109043 I match the residue reported by Li De Jing

(am now proceeding to primenet-issued double-checks)

I matched the same user's residue for 36475279.

Completed TF'ing all of the exponents, no factors found.

Don't forget to check in your result? :smile: I didn't see it:

fivemack 2015-10-02 07:12

This is probably a dumb question, but how do I do that?

I had rather thought the software had done it for me when I joined primenet; do I just log in and copy-paste my results.txt file?
