How do I get started?
Can anyone, please in very downworth language, tell me, how to make the factor3_2b work, such as one doesn't have to test a whole range on thousands of numbers by hand, by using the factor3_2 program. So can anyone fast help me and let me know. I have downloadet the following zip file (33280-9), from the 100 million digit prefactoring project and now want's to factor the numbers, since I have written to the given e-mail and reserved the numbers, I just can't seem to understand what to do, because everytime I write in the "factor3_2b" program the following "factor3_2 <worktodo.ini" or "factor3_2 <input.txt", the cmd window just shuts down and nothing further happens, so how do I get to start working on all the exponents in the given worktodo.ini file - such as I don't have to manually type the exponents in and test them - and that by the way is not a problem... to test exponents manually, but my passions is not build up to that. So please help me, and help me fast, so I can get going and work on my exponents and help math science achieve a lot og new knowledge.

I don't think I can help you much, I never use the batch process myself, but I know that for either one to work you have to have the supporting cygwin dll files. Do you have the "cygwin1.dll" and the "cyggmp-3.dll" files?

Thanks for the reply
Joshua, I have both of the dll files. But thanks for trying to help. I guess it is not so bad after all, to use the manual factoring program, even though it does delay the progress by far - but anyway there is a long time untill we reach the predicted time for finding the first 100 million and first 1 billion digit mersenne prime. Have fun.

[QUOTE=KEP] ...everytime I write in the "factor3_2b" program the following "factor3_2 <worktodo.ini" or "factor3_2 <input.txt", the cmd window just shuts down and nothing further happens,


Sorry for asking that, but I got the impression that you are using the wrong exe lile for batch work.

factor3_2 is used for single exponent factoring
factor3_2b is used ONLY for batch factoring

so, if you type "factor3_2 <input.txt" nothing really happens, as you should have typed "factor3_2[B]b[/B] <input.txt" instead at the command prompt.
