My remembering of when version 25 clients do P-1 is about the same as James'.

[quote=Uncwilly;131153]Slightly un-related, I noticed that the factoring limits went up.

M4752xxxx - 69[/quote]
Doubles the time needed, but since we are near optimal,
the crudeness of the jump is justified by simplifying of
programming everything: little to be gained by refining the
boundaries. The extra chance of finding a factor is small (1/69?), but
just worthwhile.
I presume two LLtests take 69 times longer than the TF.

Is this normal/expected?

The chance that the exponent you are testing will yield a Mersenne prime
is about 1 in 380817.

I may have selected doing some Fermat ECMs at one point. Should I throw the 2nd one back or is this expected?

Prime95,

Any thought about adding results for the different projects under the "Progress Reports"? Just asking as most of the entries in the results files - "Recent 1000 Results" and "Recent 1000 Cleared" are Trial Factoring to low limits. Would like to see the results of the P-1 and ECM efforts (I'm not really doing any LL and Double check work).

have u changed the pc it is running on
to fix it delete local.txt

[QUOTE=henryzz;131842]have u changed the pc it is running on

that explains it then
i thought it was just the cpu it recorded but it seems it is lots more

It is not an error to be given the same Fermat number to ECM. Just let it be.

I was nailed by the infite loop too. I fixed this a few weeks ago in the as-yet-unreleased v25.7.

The Windows reinstall caused prime95 to "worry" that you had copied the full prime95 folder to a new machine. Thus, the two computers might be testing the same numbers and/or reporting the same computer name.

I'll look at this - it is a worthwhile idea.
