How do you guys do this?
 

Hello, I'm new to this group and I was wondering how LMHers look for new primes. Is there some kind of code you use in Prime95? Do you generate a list of prime numbers in the range you wish to test and enter those manually? After the factoring is done, do you also do LL tests on those numbers or do you send them to someone else to test? I know I have a lot of questions, but any help you can give would be appreciated.

Thanks

Thomas

They don't. LMHers are trying to factor numbers so a LL test won't have to be run.

Just the normal factoring code in prime95. But connection with the primenet server is turned off, and a FactorOverride=n line in prime.ini

You'll have to create a worktodo.ini yourself. You can do this using [url=ftp://mersenne.org/gimps/decomp.zip] decomp.zip[/url] and [url=ftp://mersenne.org/gimps/nofactor.zip] nofactor.zip[/url]

Make a reservation on this forum to avoid duplicating work

Normally factoring is done only 1 or 2 bits deeper then it's currentely done, but more factoring is needed before a LL should be done. After finishing a range, or every few weeks you can send the results to George Woltman, and let other LMHers know that you finished your range.
