PRPnet rally Apr. 18th-25th
 

Hi everyone,

It's time to have another rally. It will begin Wed, Apr. 18 at 7 PM GMT and finish 168 hours later on Wed., Apr. 25 at 7 PM GMT. That is 3 PM EDT and 2 PM CDT in the U.S.

Like last time, the rally will be focusing on our 14th drive, that is k=600-1001 for n>1M, in order that the range can continue to play "catch up" with our 13th drive. That means PRPnet port 2000, which should be in the vicinity of n=1.12M-1.15M during the rally. A prime at that level should come in around 1000th-1500th place in the top-5000 list.

Although Lennart and PrimeSearchTeam continued their dominance in the last rally, there were many interesting battles for 2nd, 3rd, and 4th place, both in the individual and team races. Let's see if we can make this one just as interesting.

PRPnet config info.:
server = "www.noprimeleftbehind.net"
port = 2000

Or, in terms of a prpclient.ini config line:
server=G2000:100:1:noprimeleftbehind.net:2000

Be sure and change your userID to whatever ID you prefer. Most people use their ID here at mersenneforum. It is also best to set the cache to something in the vicinity of 2 to 10 pairs.

Everyone...don't forget...rally starts in about 1-1/2 days. :smile:

I've posted the [url=http://www.primegrid.com/forum_thread.php?id=4276]announcement[/url] at PrimeGrid just now--its belatedness is entirely my fault, I apologize without excuse. :redface: Someone mentioned to me last time that my PrimeGrid rally announcements have tended to be rather over-verbose (they kept getting bigger with each successive rally) so I cut it down quite a bit this time--hopefully the most important information will be front and center. :smile:

I've also cross-posted the announcement from this thread to the Free-DC and AMD Users forums.

Question:
Is there any advantage to upgrading the PRPclient to the latest version?

I have previously run version 4.3.7 for Windows on NPLB and version 5.0.5 for Windows for PrimeGrid.

The rally started a little under 3 hours ago. Good luck everyone! :smile:

First time doing one of the NPLB rallies (I am usually doing PrimeGrid PRPnet stuff), and I am curious why my team name is not showing up? I only added the NPLB port to already working PRPnet installs with the team name specified (as it is for PrimeGrid). Am I missing something?

Thanks Lennart!

I'll change it up here a bit then...may I be added to the PrimeSearchTeam, please.

Done

We are on track to beat the snot out of the previous rally. :smile:

Close battle for 2nd between ROLP and Free-DC. :smile:

Darn ISP has been down the last few days, so been doing off-line testing but should be back up to speed here in a few hours.

Home stretch. 13 hours left.
Crunch-em if you got 'em.

What a battle for 2nd in the team stats and 3rd in the individual stats! :smile: Will James (Beyond) be able to get his ISP up in time for Free-DC to overtake ROLP? Oh, the drama! lol

As for Ian and me, I don't have anything more I can throw at it so if he stays on through the end, he's got 3rd place. Ian's and James's participation in the rally has made for 2 very intersting battles.

Congratulations everyone.

With a combined rally Pair Score of 1.8M this was the largest amount of work completed in a NPLB Rally. This meant that, even though the work required is greater, we completed almost as many pairs as last time.

Finding 17 primes in the push was a terrific bonus. We were luckier than this once, in Jan-2011, but we have come so far since then that the Prime Scores are much mightier now yielding our highest rally combined Prime Score ever and all of them came in to the Top5000 List just outside the top 1000.

While odicin stuck around for BOINC Confederation and Neo kept the flag flying for team AtP, Ralph_Recker put in a good effort for Sicituradastra. and Alexis_Kravtchenko popped in at the end to see what was happening which put team Ukraine on the board bringing the rally team representation up to 8, which is also the most we have had in a NPLB Rally.

Thanks to Gary and Max for organizing and putting on a hugely successful rally.

It was a hugely successful rally!

It looks like ROLP barely held off Free-DC for 2nd place. :smile:

I don't have the large number of machines running that i used too.
Can't see myself ever going back to that either, the running costs were huge.

The PC's i use for crunching when i have a mind too, are all SB with
the exception of the Bulldozer which failed 4th grade maths :(

The Sandy's with the AVX enabled client fly through the pairs.
You only need a handfull of them to put up quite respectable scores.
The electricity bill is much lower and the house isn't at sauna temperature.

It really was close! A single CPU could've easily made the difference of 9,872.839 pair score; my single i5-750, crunching for about 5 days of the rally, crunched 11,567.956 score worth - though it doesn't entirely make sense to say so, I could say that I made us beat out Free-DC for 2nd :smile:.
