I have completed 60-66T. Do you want those now, also? I have 75-88T on 12 cores, part-time. It will take a few days to complete (I lazily assigned 1T/core, before I had my new support scripts written).
With the new scripts, I can much more easily distribute work, which also means that I can make faster progress. The machines aren't available all the time, but when I can pull in all of my fast cores that are currently available they can complete 5T in just over 3 hours, so it shouldn't take too long to get everything done.

Sheep, send what you have done on the 29th or 30th, so I can apply the factors-found before releasing that large block of files. Don't worry about having continuous blocks- gaps don't really matter at this depth.

With Sheep on the job, we'll likely release everything to 900k on 1 Nov. He'll get us to 80T+ by then easily. We might finally have enough work for all the cores we can throw at this project.

[quote=VBCurtis;116821]Gary- send me whatever you have sieved on Wednesday night. I'll remove the factors and release up to 780k then, then whatever range necessary (900k?) to satisfy demand on 11/1. We're now in a range where sieving is in the ballpark of enough, so I'm fine with your suggestion. When we were at 20T and "proper" depth was 50T+, I wasn't so keen on that when a week's delay meant 50% more sieving.

At this pace, 900k-1M will be released on 11/15.

Mass sieve: We already have masser's files, 8 k's from 700k-1M. I plan to perhaps extend these to 2M and sieve them a while. Cruelty has 12 k's to 2M also, and he plans to LLR each until he finds a prime, then release the file for public consumption. So perhaps such a plan as we seem to want already exists-- we should encourage people to submit untested sieves when they release numbers.

Wow, cool! Sounds good to me on both fronts. Factors coming your way Wednesday. I doubt you'll need any more of my 'piddly' sieving now.

Sounds awesome on those big sieve files. It'd be cool to bring all of those various sieved files together and include them in one big huge massive sieve for you, Sheep, and perhaps Amphoria to hack away at.

Let me know if you want me to follow up with anybody on getting them or anything else related to such an effort. I think I read that Kosmaj has Masser's files.

Sheep should be called as Sir Sheep....great effort...

BlisteringSheep 2007-10-24 05:15

I'm about an hour away from having 60-87T sieved. 1564 factors so far. Do you want me to just keep going? If so, how far?

gd_barnes 2007-10-24 21:59

k=5
630-665 complete
no primes found
results file to be sent tonight

Ready for 740-760 whenever. I will reserve one more range after I get started on that one and that will be all for k=5 unless some sieving help is needed.

Curtis, I'll send you the factors found so far for the sieve range of P=53T-58T later tonight.

Kosmaj, the following ranges have been reserved:
700K-720K Carlos
720K-740K Patrick
740K-760K me


Gary

em99010pepe 2007-10-24 22:06

Reserving 760k-800k. I need this range one day after getting the 700k-720k range...:grin:

Carlos

gd_barnes 2007-10-25 05:38

I'll go ahead and reserve 800-820 now. That'll give me one range searched in each grouping of n=100K for n=400-900K, i.e. one in 400-500K, 500-600K, etc. I'll make that my last range for this effort for now. Let's make it a goal to have everything LLR'd through n=1M by the end of 2007. If we're close by early Dec. but it doesn't quite look like we'll make it, I will pick up another range or two as needed, suspend part of another effort, and throw 4 cores on 2 machines at it.

Edit: Curtis, if the 800-820 interferes with the ranges you need to get a prime for your goal, I'm fine with any range to LLR in the 800's.


Gary

VBCurtis 2007-10-25 07:44

The following ranges have been sent out:
665-700 me
700-720 and 760-800 carlos
720-740 patrick
740-760 and 800-820 Gary

600 to 630 complete, no primes.

reserving 820 to 850.

Future reservations can be 10k or 20k blocks, as testing time is quite a bit higher than when we were at 500k. At 1M, we'll convert to all 10k-wide reservations. For now, choose whatever is best for your situation. Carlos, you're running 3 cores, so 30k or more is fine, so you can keep all of them running. Sheep has us sieved sufficiently deep for n<1M, so future reservations will be emailed within a day or two.

em99010pepe 2007-10-25 08:23

Curtis,

Thanks for the ranges...who said I was only adding 3 cores?!?!?! :wink:
I said previously at least 5....

Carlos

BlisteringSheep 2007-10-25 08:30

Factors for 60-100T have been sent. The next stage will begin tomorrow.
