Sieving drive for k=2000-3400 n=50K-1M - Page 13

gd_barnes · 2009-06-18, 22:05

Yes, a tremendous help by Lennart! He had previously helped to do a large part of a couple of previous sieving drives so hats off to him!

Let's not forget Bruce who has also previously been a huge help on sieving and putting a large amount of resources for extended periods on the less popular non-top-5000 ranges.

If anyone is still interested in helping sieve, our next big effort is k=300-400 for n=1M-2M. Ian started that one a couple of months ago (I think) over on the other forum. The last I checked, it was complete to P=4T with Lennart and possibly Ian having completed some 1T ranges for P>5T.

Optimal sieve depth for that one is likely P>100T, even for breaking off the lower n-range; perhaps n=1M-1.2M. I would call it "low medium" priority at this point but I would guess that k=300-400 will be complete to n=1M within 3 months so we don't want to let it sit idle for too long. With only 50 k's, the sieve rate should be quite a bit faster than our normal huge sieving drives.

I'm looking forward to having NPLB have ranges around n=100K, n=450K-470K, 500K-520K, 665K-675K, 720K-740K, and 1M all available in various drives at the same time. I think that at our current processing rate (and anticipated demand for the new drive), that is close to what we would have by the time k=300-400 is complete to n=1M and that sieving drive is optimal for the lower n-range.

Would ther also be individual k´s or something similary things on this drives?

I´ve learned to love this individual k´s. ;)

Yes, definitely. We'll also likely do something like the little "6k drives" on the side, perhaps with anywhere from 5 to 10 k's. I like those the best for higher n-ranges because I don't then feel like I'm "stuck" with 1-2 barren k's.

In a synopsis, we probably won't do anything much different for this range for n>1M than what we've been doing for n<=1M.

Thanks Gary. So I will look in a good mood in the future. ;)

Lennart · 2009-06-19, 21:39

Up to 29T will be done this evening.
29700G-30T will be done tomorrow 1400 UTC

29000G-29700G completed yesterday. I have all factors from everyone now.

Later tonight or early morning depending on your time zone, I'll get a new drive started.

Excellent work everyone!

What is the schedule/plan for starting non-top-5000 work in this range?
Will we be using PRPNet?

Gary and I are currently discussing that. So far, we know that we'll be using k=3200-3400, n=50K-425K with PRPnet as a stress test. That will probably be the first thing we do with non-top-5000 work in the k=2000-3400 range; once we've verified that PRPnet works stably with lots of very small numbers, we may consider doing the much larger k=2000-3000, n=50K-425K range through it as well.
