PrimeGrid’s Challenge Series continues with the "Back to the Future Challenge". It is set to begin in just over a day and a half - 13 Sept and will continue 14 days to the 27th.

This will be a very CPU intensive and demanding Challenge. If that doesn't turn you off, please come take a look and see if you're interested. AMD Users is current ranked 45th in the overall Challenge Series team standings.

I'll probably put a core in it. Currently busy with SIMAP and LHC@Home WUs. Those WUs don't come that often on those 2 projects.

With less than 5 days remaining in the "Back to the Future Challenge", AMD Users is ranked 32nd. Top Teams

The top 40 Teams will earn Challenge Points. Best of Luck!

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.

I reckon we should try and organise a big push for this project to boost us in the challenge rankings...what does everyone else think?

[jmblazek]

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.

Hi All,
The next round starts today so check the PG site for details ad let boost AMD Users up the ranks of the challenge series!

The challenge was postponed due to server issues...

http://www.primegrid.com/forum_thread.php?id=1138#11995 PrimeGrid's Challenge series continues with the Winter Solstice Challenge. Please come join us in observing Nature's ending/beginning of a cycle. A 4 day (96 hour) Challenge is being offered on PrimeGrid's Prime Sierpinski Project (Sieve) application. To participate in the Challenge, please select only the Prime Sierpinski Project (Sieve) project in your PrimeGrid preferences section. The challenge will begin 17 December 2008 12:04 UTC and end on the Winter Solstice 21 December 2008 12:04 UTC. Application builds are available for Linux 32 & 64 bit and Windows 32 & 64 bit. Note: 64 bit Windows and 64 bit Linux benefit from a 1.7X speed advantage over 32 bit...so 1.7X the credit.

There's the last one of the year. Everyone need to help out AMD Users in the one. A short run with good credit. From personal experience, I can verify the 64 bit advantage, so ...
