Reserving n=520K-560K for port 8000 with our nice new file sieved to P=20T.

This should keep it well stocked through the rally and then some. :smile:

David, the file has been sent.

Gary, the file has been loaded.

Results and primes up to n=520K have been verified against the usual places. No problems found.

gd_barnes 2009-04-17 22:28

Note to the admins:

I'm keeping a spreadsheet of all primes found since n=528K as per the Emails that are received from the servers due the speed at which they come in shortly before, during, and shortly after rallies. If any primes go more than a day without being reported, I'll Email or PM folks.

I'm reporting primes for LaurenU2 at top-5000; under his name of course. I'm not familiar with a couple of the ID's in the server. The possibility exists that we may need to report some primes for others or give them detailed instructions for doing so.

MrOzzy now has 2 primes that he needs to report. I PM'd and Emailed him with the 1st one that is now close to a day old. He should see the 2nd one and report them both since the regular notification Email went to him.

At the current rate, we'll likely past n=545K with the rally but I think people are still adding cores so we may be able to get close to n=550K! :smile:

Reserving n=560K-600K for port 8000.

gd_barnes 2009-04-22 03:36


Please process results to me for n=520K-540K for this drive. As of the close of today, all pairs for n<=540K should be in the server results.

Later tonight, I'll take the factors from the sieve drive for P=20T-25T and apply them to that file. I'll then send you a file for n=600K-650K to load into port 8000. We're blowing through this drive at break-neck speed.

PCZ and Vaughan,

Could I talk you guys into moving most of your port 8000 machines over to Ironbit's ports 4000 (5th drive) and 5000 (6th drive) within the next 1-2 weeks? Within that time, we really need anywhere from about 5-10 quads running those instead of port 8000. It'd be good if about an equal # were on each port. I have 6 quads running port 5000 on the 6th drive but it is well behind the 5th and 7th drives. Ian has what appears to be about 4-5 quads running the 7th drive. With it ahead of the other 2 drives, we don't need any more on port GB4000 at this time. Only ports IB4000 and 5000 are lacking.

Several reasons:

1. Those drives will test a little faster at the same size for some n-ranges. You'll find slightly more primes per CPU hour at the same size.

2. There are slightly less already known primes on them.

3. The project intent is to keep the lower k's at deeper searched depths than higher k's for the above 2 reasons. I'd like to avoid a situation where k=1400-2000 is at n>650K and k=600-800 is at n<650K. Also, Benson's k=1005-1400 will not be at n=600K by the time we hit n=600K for k=1400-2000.

I don't want to inconvience the non-regular Free-DC searchers so I'm choosing to inconvience the regulars instead. :-)

Initially, the tests will take a little longer than port 8000 because the drives are at higher n-ranges but they won't be for much longer with so many cores on 8000. When all are testing the same size, the lower k-ranges should test faster for some n-ranges.

The next couple of rallies will be run on a combination of ports 4000/5000/8000 assuming that they are at close to the same search depth.

What an excellent situation to have to deal with! :-)

It sounds like your going to have to jump through some hoops Gary.
Free-DC is here to stay for the month of May.
In a few more days, there will be even more knpairs being consumed. :big grin:

Those are some hoops we don't mind jumping through. :smile:

Reserving n=600K-650K for port 8000. The file has been sent to David.

We're now using a file sieved to P=25T. :smile:

PCZ 2009-05-02 06:45

Lauren will suck port 8000 dry on his own :)

I will look at changing the ini files a bit later today.

All times are UTC. The time now is 06:28.
