Impressive!



Willful ignorance of science is not commendable. Refusing to learn the difference between a credible source and a shill is criminally stupid.

As a complete mathematical ignoramus, I have questions.

If we know this is the fourth-largest prime numbers, then must we already have discovered the prime numbers ranked 1-3?

And how do you discover the largest number without, on the way there, discovering smaller numbers?

And do we really KNOW it's the largest number?

These are the largest discovered to date, so we will (probably) find a larger prime number eventually. I don't think they test numbers in order, and there are multiple people working on it in different ways, which leads to sometimes finding a larger number first.

Wow, they have a client that allows someone to provide their computer's processing power in order to help with the search. That's better than helping analyze radio waves from outer space for SETI ( http://setiathome.ssl.berkeley.edu/ ) like my computer used to be doing when I was away.



NOTE: The above post makes no sense. We apologize for the inconvenience.

There are actually a number of distributed computing (DC) projects out there right now. I've been a part of a few of the teams (a very small part!) over at Ars over the last year or so.

I really recommend the Folding@Home project if you are interested in doing something like this. If power were just cheaper I'd probably have a farm of computers running this project. It is a protein folding simulation run by Stanford University.

The guys over in the DC forums at Ars are generally very friendly. It's a very tech savvy site, but I think they'd be happy to talk to some new blood that would crunch numbers for them.

TER (Team Egg Roll) is their folding team. TPR (Team Prime Rib) is their Seventeen or Bust team. TLC (Team Lamb Chop) is their Seti team. You can read a little about the projects and teams at their forums here: http://episteme.arstechnica.com/eve/ubb.x?a=frm&s=50009562&f=122097561

At one point I was living in an apartment and had two Sparcstation 20s, a PPro 200, a laptop, and my regular PIII desktop all running the RC5 cracker...Power was included in my rent.

I moved into another apartment where power wasn't included. I lasted one billing cycle. This was when I realized that there's at least one very good reason not to run Sun gear at home...

The landlord in the first place must figure I was running a grow op. Or maybe the combined BTU output lowered my heating bill enough that there was balance...

Send me a PM. I can probably send you a card for the price of shipping and you can test it to see if it is good enough. You don't want anything high end because it will have a fan (and more noise) so you are looking low end.
