feeding back results from Prime95
 
Hi there,
I'd like to contribute to trial factoring > 1,000,000,000. However, I wasn't succesful in installing mfaktc or mfakto on my computer.
I got some assignments from [url]http://www.mersenne.ca/tf1G.php[/url] and inserted them in the worktodo.txt of Prime95.
I got the following error message: "PrimeNet error 40: No assignment" because PrimeNet accepts only smaller numbers.
How can I upload the results now?

What [FONT="Franklin Gothic Medium"]exponents[/FONT] were you testing?

[FONT="Franklin Gothic Medium"]Exponents[/FONT] in the 332,000,000 range yield [FONT="Arial Black"][COLOR="Purple"]decimal numbers[/COLOR][/FONT] in the 100,000,000 digit range.

If you want to run numbers in the 1,000,000,000[COLOR="purple"][FONT="Arial Black"] decimal digit[/FONT][/COLOR] range your [FONT="Franklin Gothic Medium"]exponents[/FONT] need to be in the 3,320,000,000 range.

What else did the error say? Result not needed?

Mersenne.ca accepts factoring data for exponents up to 4.29 billion (2[SUP]32[/SUP]). However Mersenne.org (PrimeNet) only stores data for exponents up to 1.00 billion.

[URL="http://www.mersenne.ca/bulk-factors.php"]Here is the link to the new page[/URL] on Mersenne.ca where you upload your results file. It expects an mfaktc/mfakto output file, but maybe the format is similar to mprime, I'm not sure.

mprime is not as efficient as mfaktc/mfakto for factoring. Actually, I'm not sure if mprime is even capable of factoring exponents larger than 1.00 billion. Maybe you should try again to see if you can install mfaktc/mfakto.

I found a solution.
I copy the assignments from [URL]http://www.mersenne.ca/tf1G.php[/URL] into the worktodo.txt of Prime95 and run them on Prime95.
Then I take the results from results.txt and bring them into a format that can be read at [url]http://www.mersenne.ca/bulk-factors.php[/url].

"UID: martinwilke1980, M1250011439 no factor from 2^64 to 2^65, We4: DD667E59"
is reformatted to "no factor for M1250011439 from 2^64 to 2^65 [mfaktc 0.21 ]"

"UID: martinwilke1980, M1250011927 has a factor: 40071650026507719343 (TF:64-66)"
is reformatted to "M1250011927 has a factor: 40071650026507719343"

I made a spreadsheat that parses the input text and that creates the output text.

I copy the output text into a texteditor, save it as a txt file and then upload it.
