I wanted to get the results up quicker. But it has been the holidays. LOL

Anyway, this was PG's last Challenge of the year. We did well for such a small team. This last challenge's results:

I sure hope I didn't miss anyone. If I did, sorry. It was crazy going through 1815 people looking for just our team. LOL

We ended this challenge in 27 place giving us 6 points. Nice going team. Without those 6 points we would have fallen one more spot in the overall for the year. So great going.

We had a few bigger ones and a few smaller ones. The bigger ones were on the harder, cpu intensive, challenges. Not a whole lot of people show for those. But this last challenge was a whole new ball of wax with adding of cuda. I hope they get an ati app before have another challenge with gpu's. I think we got a little lucking having Sams cuda cards helping out.

Anyway, was a great year of challenges. I hope to see those that helped out in the 09 challenges show up for some of the 0 10 challenges. They don't have anything listed for them yet, but when they do I will let ya know.

i'm waiting for ATI apps also then we can really rack up the points WTG Team

February is a couple of days away which means it's time for the Tour de Primes. 2 is the first prime number...and the only even one. Therefore, we have declared February, the 2nd month, as prime month.We're offering a small competition in tribute to this unique prime number. There are no points to be gained or awards to be won...just a simple colored jersey (Yellow, Green, and Checkered) at the end of the month. No pressure or stress other than what you put on yourself. :) For more information, please see Tour de Primes 2010.

Rick

24 hours into the Challenge and Cupid and the tiger have been very successful in their hunt for primes - already snagging over 35 "Top 5000" primes. 48 hours remain so it's not too late to jump in the fray and see if you too can capture a prime. For more information, please see this forum thread.

I can only find 3 of us crunching in this Challenge so far. I might have missed someone though. But theres still time to get in and get a days worth done. They are cpu intensive wu's, but they are pretty short. Around 20 mins on the quad. Right now I am down a quad too. The PS went out and new one wont be here till wednesday.

So join in if you can, make sure to pick the correct app in your preferences at PG to get the right wu's for the challenge.

Rick

17 Feb 2010:

Less than 4 hours remain. The hunt has been very successful for Cupid and the Tiger. Just as PrimeGrid's validator is struggling to keep up with the Challenge, the Prime Pages' validator is struggling to keep up with the prime submissions. :D Over 75 "Top 5000" primes have been found so far!!!There's still time to join the hunt. For more information, please see this forum thread.

21 Feb 2010:

We will be doing software upgrades on the servers in the upcoming few hours that might make the website temporarily inaccessible. We will update this post when the updates are complete.
Update 14:05 UTC: maintenance has been completed successfully.
Update 15:07 UTC: turns out database is misbehaving, so we need to extend the outage.
Update 17:00 UTC: it seems that everything is running fine.

23 Feb 2010:

The results are final. Cupid and the Tiger ravaged the primes - bringing in an unprecedented 110 "new" primes to the Prime Pages with over half of those making it into the Top 1000. Over 2M tasks (1M WU's) were completed resulting in over 23M cobblestones awarded...an astounding amount of work done for an LLR Challenge. Congratulations to SETI.USA as the top team and Mr. Hankey as the top individual.Thank you to everyone who participated!!! For more stats and information, please see this forum post.

PrimeGrid's Challenge series continues with the Ides of March Challenge. Once again we observe Caesar's demise by finding factors that will bring some k/n pairs to their demise. A 24 hour (15-16 March) Challenge is being offered on PrimeGrid's Prime Sierpinski Project/Seventeen or Bust (Sieve) application. For more information, please see this forum post.

01 Mar 2010:

A very productive month for the Tour de Primes. 309 "Top 5000" primes were discovered, easily surpassing last year's mark of 212. lennart SM5YMT of Sweden and the PrimeSearchTeam once again topped the leader boards winning his second yellow jersey in a row. He also picked up the green jersey for the first time. [SG]marodeur6 of Germany and team SETI.Germany takes home the checkered jersey.For more details about the tour and complete standings, please see this forum post.

Well its that time again. PrimeGrids March Challenge.

I didn't post much on the last challenge. Only had a couple people and we were not near the points rankings. One of the few we didn't make it into the points. Hoping for a better challenge this time around from the team.

From PG:

A 24 hour Challenge is being offered on PrimeGrid's Prime Sierpinski Project/Seventeen or Bust (Sieve) application.

To participate in the Challenge, please select only the PSP/SoB (Sieve) project in your PrimeGrid preferences section. The challenge will begin 15 March 2010 18:00 UTC and end 16 March 2010 18:00 UTC. Application builds are available for MacIntel, Linux 32 & 64 bit and Windows 32 & 64 bit. Note: 64 bit builds benefit from a 1.7X speed advantage over 32 bit...so 1.7X the credit. :)

Recommendation: The PSP/SoB (Sieve) application requires a one time download of a 10MB sieve file. Please consider running a few PSP/SoB (Sieve) WU's before the Challenge begins so your client will already have the sieve file. This way, bandwidth can be used to deliver WU's instead of the sieve file. :) Thank you!

So its gonna be a nice 24hour challenge on short easy PSP Sieve wu's. Hope to see you guys and gals there. If anyone has any questions about the challenge, let me know.

Rick

Anyone? It started 6 hours ago, which means 18 hours left people, get cracking!

I got Buga, Me, Bird-Dog and Labbie. Anyone else?

17 Mar 2010:

"Et tu, Brute?" Yes, even Brutus stopped by and took down a few k/n pairs. He and the rest of the "senators" did the dirty work of rounding up over 400 prime wannabe's and placing them forever in the realm of composites. While they won't make the same notoriety as Caesar did, they will still rest in peace.The results are final. Just over 1.01P was sieved in the 24 hours of the Challenge...an astounding amount of work done. Congratulations to SETI.USA as the top team and Shanky as the top individual.Thank you to everyone who participated!!! For more stats and information, please see this forum post.
