The Prime Time Challenge

[jmblazek]

PrimeGrid’s Challenge series continues with the Prime Time Challenge (14-16 November 2008). It's high time we initiated the new server and what better way to do it than with a Challenge. Also, it's time to return to the thrill of finding primes...and for that, we turn to PrimeGrid's newest project, the Proth Prime Search.

Currently, these tests are rather short so this will also give us a good opportunity to "stress" test and fine tune the new server. The Proth Prime Search is slowly working its way up to the "reportable" prime level in Chris Caldwell's The Largest Known Primes Database!

So please come join us as we initiate the new server and bring the Proth Prime Search to the "reportable" prime level. For more information, please see this forum thread.

The key to an effective prime search is having a good sieve file. For the past several months, our primary focus has been on getting the PPS Sieve deep enough to start LLRing. While we have made great strides in this effort, we still need more help. Leading up to this Challenge, anyone with a 64 bit multiple core system is encouraged to join the Proth Prime Search (PPS) sieving effort. Please see this post if you are interested.
