Trialfactoring M47493253

[Phantomas]

several month ago i got the exponent with my old pentium 120 laptop.
In november 2008 I switched it to server v5, but couldn't get a correct assignment for the old exponent. I decided to let it run, because only a few weeks of work had to be done.

On December 25th the exponent was done, an the pc tried to check it in.
But the server answer was

Sending result to server: UID: Phantomas/JTLAPP120, M47493253 no factor from 2^68 to 2^69, Wd1: C7DF3C11

PrimeNet error 40: No assignment
TF result for M47493253 was not needed

I tried to check it in manual, but got the same answer.

No factor lines found: 1
Processing result: M47493253 no factor from 2^68 to 2^69, Wd1: C7DF3C11
Error code: 40, error text: TF result for M47493253 was not needed
Factors found: 0
P-1 lines found: 0
LL lines found: 0
Mlucas lines found: 0
Glucas (G29) lines found: 0
Glucas lines found: 0
ECM lines found: 0

Then I checked the Exponentstatus:

47493253No factors below2^64
AssignedTrial factoring to "ANONYMOUS" on 2008-12-17

Why is my result not needed? Can anybody explain this?

PrimeNet is not accepting the result because it is missing the trial factoring between 2^64 and 2^68, that was also the reason it was not accepting to register your work. You should change the line you input to the manual results to :
M47493253 no factor to 2^69, Wd1: C7DF3C11 (the old style)
or
M47493253 no factor from 2^65 to 2^69, Wd1: C7DF3C11 (the new style.)

If you want the credit (2,3601 GHz days) be sure you log on the server before turning in your results.

But is it shure, that the factoring from 2^65 to 2^68 is done?
It seem's that I have only testet from 2^68 to 2^69, or did I missed something?

I found the assignment in the log:

is the term "&sf=64&ef=69" the start / end?

ok, yes, it must be, I'l try that immidiately ;-)

Nope, it didn't accept it.

I rechecked the logfile, and I think there went something very wrong between 16th and 19th December:

It seems I Lost one assignemnet, maybe 65 to 68?
Maybe I made a mistake while trying to get the "N/A" away.....

I think the work is gone.....

You can't check-in the modified results line because the checksum is not valid.

I can.

The result is now recorded and you received the CPU credit.

[Phantomas]

Thanks a lot George!

Can you explain what happend and why?

regards

[Prime95]

The previous explanation was accurate. When v25 resumes a v24 TF assignment it erroneously reports only the bit levels that v25 completed (not outputting the 2^64 - 2^68 that v24 completed).

[Phantomas]

Aah, yes. I hadn't understand, why that was missing in the line.
