Mersenne BOINC coming? - Page 2

This Mersenne BOINC project may be planning to do a similar thing with Prime95.

BTW: yoyo@home doesn't use a modified version of distributed.net client. It is the original one. There is just a wrapper arround it to handle the Boinc api. Don't know about dnetc@home, but I think it is the same there.

There are only Linux@Intel and Linux@AMD versions of the application - perfect match for me. I'd like to hear more from Sebastian on the implementation and availability of the source code.

I attached to the project and received a few tasks, some of which left me head-scratching!

...Why would I want to waste electricity on LL tests on Mp's that apparently weren't even trial factored there?!

they have trivial factors!

(the silver lining is ...well, they are only trying prime p's. That's a relief.)

I've noticed that sites it's jumpy about are usually new. I should have said that previously.

The fine print says, "... This recommendation is based on how long the site has been around and the strength of its security. ... Site is not a known phishing or spyware distributor. Site was first registered on 11/03/10 (less than 3 month). Site is located in Poland, Eastern Europe."

Yes, if it's running prime95, whose EULA begins with, "The full legal rules are at http://mersenne.org/legal/" and includes "At the time of this software release, the Electronic Frontier Foundation is offering a $150,000 award to the first person or group to discover a hundred million digit prime number. If you find such a prime with the software provided, GIMPS will claim the award and distribute the award according to the rules published at http://mersenne.org/legal/#awards"

As for Linux: mprime's EULA is around here somewhere ...

No one has to share with GIMPS ... if they write their own prime-testing software.

Is it correct that the prize for the 10 million digit (Mersenne) prime
has not yet been officially awarded due to the fact that not all
smaller Mersenne Numbers have been fully tested?

lavalamp · 2010-12-19, 21:30

If it has not yet been awarded, then it is not because the other numbers have not been fully tested. The prize was merely for finding the first 10 million digit prime, (as well as having it verified and published in a suitable journal and possibly some other conditions too).

Is there any prize in the offing for finding/proving the entire collection
of the first 50, 60, or 100 Mersenne Prime Exponents?

My Multi-Precison (Integer) Calculator does have a function for testing
Mersenne numbers in a loop, but it's too slow to reach 5-digit numbers (at this time).

927 users attached at the moment (some familiar faces there!).
Most obviously have the credit of 0, because there are no Windows workers.

It's not correct.
