Rally Apr. 17th-19th
 
Time for another rally! Let's do one on port 8000 from April 17th to 19th starting and ending at the usual 7 PM GMT.

There's no need to post the # of cores you'll be bringing. David's servers have proven that they are hearty enough to handle anything we throw at them. No proxy servers please.

David, can you bring a few Free-DC folks along for another BBQ? :smile:

Please post any questions or comments in this thread.

PCZ has prodded already. We'll see what comes to the table when it's time.
I assume Brian will remind everyone once more as the time gets closer to start the rally.

More tuning on the stats DB >processing< * completed.
Testing has revealed it can now process about 50,000 records per minute.
Bring it on!

>the DB software is already finely tuned by Bok, it was the data processing scripts that have been markedly improved upon<

OK, I've got 42 cores on this thing now. Let's get them warmed up for the after Easter Rally. :smile:

Bring on the mercenaries! :missingteeth:

Ok, Free-DC has been notified.
No telling how many cores will come to this one being it's only going to last just a couple days.

I'm fairly certain PCZ and I'll be there. :big grin:

I'll be pausing the mini-drive for this.

I only have a Q6600 so try to leave some primes for me. Gonna be a challenge for me to get some primes. :)

No more challenge than anything else at the same n-range. The only reason it will be more difficult then the mini-drive is because we'll be testing n>520000 so the tests are larger. Your mini-drive is only around n=422000.

Some people do have a bit of a distaste for the servers due to the random nature in which they receive the tests. But technically, you'll find no more or no less primes in the long run on them then when running manual tests like the mini-drive as long as the n-range and sieve depth are similar.

We appreciate anyone who can contribute, whether they have small, medium, or large resources. The goal is fun for everyone. What I've encourged people to do is find someone or several people with similar resources and make a game within a game out of the rally to see who can do the most tests. People with similar resources to yourself are Max (mdetweiller), Mini-Geek, and Chris (Flatlander), although I think Max and Chris may have 6-8 cores total that they are running now.

@gamer007
Yes, I have gone from 2 to 4 to 6 cores over the course of 4 years and have found 189 reportable primes! I'm sure you'll soon start finding them too. :smile:

Somewhat similar situation here--for about a year or so I've had one Core 2 Duo which produced many of my primes, and then a few months back I added a Q6600. The Q6600 alone has produced plenty of primes; I've found that at current n-levels, it can crank out about 1000 k/n pairs per day on port 8000. Gary, what's the odds of finding a prime in 2000 k/n pairs on the 10th Drive at n~515K? I remember it was a bit less than 100% for n=400K, but I'm not sure about >500K.
