The Prime Time Challenge

Sat, 15 Nov 2008 17:15:00 GMT

While the Challenge has been canceled (will be rescheduled) we will continue keeping stats for the current dates (14-16 November). The reason for this is that we want to continue to stress the server so we can see the impact on different server related issues. This will help us better prepare for the Prime Time Challenge (Reloaded). :)For those who are interested, please continue to crunch Proth Prime Search LLR through 16 Nov 2008 18:00 UTC. The results will be unofficial but the process will help us greatly. Thanks for the consideration and again, we apologize for the cancellation.

The Prime Time Challenge has been canceled. While the server is fine, we are having issues that we are not yet able to resolve. We sincerely apologize for this. More information to come when we have it.

Less than 24 hours remain until the Prime Time Challenge (14-16 November 2008). The initiation process is already warming up as the load increases on the Proth Prime Search (LLR) in advance of the start. We are approaching the "reportable" level in Chris Caldwell's The Largest Known Primes Database! Come help us reach it and find a prime for yourself.For more information, please see this forum thread.

Less than a week remains until the 48hr Prime Time Challenge (14-16 November 2008). Come help us initiate the new server and maybe find a prime large enough to enter into Chris Caldwell's The Largest Known Primes Database! The Challenge will highlight PrimeGrid's newest project, the Proth Prime Search. For more information, please see this forum thread.

Preparing for the Prime Time Challenge

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 sieving effort. Please see this post if you are interested.

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.

New server is live

Mon, 27 Oct 2008 20:30:00 GMT

While I'm writing these lines, the database is already running on the shiny new server in the new rack. While Murhpy has definitely played his role today, we hope that all troubles are gone and everything will be running smooth from now on. The first minutes seem promising, and the speed has improved significantly. We'll keep you posted. Big thanks for Willy for his work on the servers, and to all donators who helped make this server a reality!

Scheduled downtime - new server installation!

Thu, 23 Oct 2008 18:10:00 GMT

We are planning a scheduled downtime of several hours on Monday, October 27. We will be relocating PrimeGrid and BOINCstats servers to the new rack, and will add a new server for PrimeGrid, which has been purchased using funds from the recent donation drive.

"Optimal" sieve depth reached!

Fri, 03 Oct 2008 16:50:00 GMT

In a review yesterday of the Cullen/Woodall Project status, it was determined that we are at "optimal" sieve depth...actually, a little beyond it. Therefore, we are stopping the 32 bit and 64 bit Cullen/Woodall Sieve applications and archiving the sieve. Cullen/Woodall LLR will remain active up to n=10M. For more information, please see this forum post.
