Wow. Was that a test of the ridiculously small lower limit that we have on reservations. lol That's a grand total of 15 tests!

Max, with only 2 k's remaining, I think we need to make n=5K the lowest test range allowed lest we be innundated with teeny reservations. Would you agree? Do I hear any objections from anyone?

I don't mind. I was just thinking of this:

Quote:

Please reserve a range that will take no longer than ~2 weeks.

The test are approaching 5 hrs each @ 2.66GHz Core2.
And the smaller the reservations, the less 'wasted' work should a prime be found below someone else. I asked for another 20k because I thought it was less admin for Max/you than 10k now, then 10k later, and I saw little interest here. (I'll probably put more cores on now that others are above me.)

(btw Does the server stop handing out tests for a k if a PRP is found?)

(assuming you mean PRPnet) As long as the server type is set to 1 - Sierpinski/Riesel, yes. Note that if a separate server finds a PRP, it will, of course, not know to stop searching that k automatically.

I usually reserve rather large ranges to always have some backup work should one or more cores run dry or find a prime and stop. I'll see how it works out with the 2 week goal. That's why I took only 9k. So a lower limit of 5k is no problem for me.

gd_barnes · 2011-02-13, 19:34

OK, I'm increasing that to 4-6 weeks now that the tests take so long. I'll also increase the minimum suggested range to n=5K. The main reason behind the time limit was to avoid wasting too much higher-n work when a prime is found. At such high n-ranges, that is not as much of an issue.

Ah, okay. I reserved this small range for manual testing on one core of my dualcore. (There's not much available out there any more that's small enough for one core, besides just running a PRPnet or LLRnet client on a server as part of a group effort.) I suppose 5K would be fine for the future since the time limit has been extended.

Yes, it does. I have your server set to servertype=1 (Sierpinski/Riesel), which as Mini-Geek said will stop testing a k when a prime is found. More precisely, it will not hand out any more tests above the prime; it still finishes up what's left below the prime to ensure that it's actually the lowest prime for that k. (Just like we do for manual reservations below a prime.)

I guess I'm a little confused. Aren't the tests taking ~4 hours each? If so, that would only take ~60 hours (~2.5 days) for 15 tests. You could still have taken an n=5K range and finished in < 2 weeks. Perhaps you only wanted 2-3 days of work. If so, I agree, there isn't much manual work to reserve that is THAT small amount of work.

Yeah...I didn't know exactly how long the tests would take so I figured I'd reserve a small 1K range and see how long that took me for future reference. In the future, 5K ranges should be plenty small.

1050K-1051K complete, no primes.

Results attached.

Puzzle-Peter · 2011-02-22, 17:42

1051K - 1060K done, no primes.
