[quote=mdettweiler;161860]Yes, we'd discussed that and such a setup is planned. However, at the time, our one existing PRPnet server (Sierp. base 6) is completely idle--come on guys, where'd everyone go? :smile: If we can get at least one or two people who are interested, then we'll go ahead and start a second PRPnet server for the single-k conjectures.[/quote]


I'll put a core or 2 on the PRPnet server here in the next few days. But first, I have to know how to run PRPnet. Max, can you send me a "PRPnet care package" so to speak?

As for all of the bases with 1 k remaining going into a PRPnet server, I totally agree but there are 3 problems:

1. I would like to make it 1-3 k's remaining.

2. No sieve files on most of them.

3. Reservations on many of them.


It will take some time but we will get there.

i would quite like to do some sieving work soon once i have compiled srxsieve on my 64-bit virtual machine.
could you suggest a sieving job of a size that i could complete it in less than a week of actual cpu time?

as far as i know sr2sieve only supports one base at the time

Okay, I'll get a PRPnet "care package" packaged up and dropped on your machines sometime later today. I don't have time this morning but I should be able to get to it sometime this afternoon/evening. :smile:

Sierp. base 23 is now at n=200K, still no primes. :ouch2: Results are attached for 185K-200K.

Continuing to 250K. :smile:

Riesel base 28 is at n=75K. No primes found since n=50K.

In addition to 1st-pass testing on the 4 k's that were at n=50K when I reserved Riesel base 28, I'm double-checking the rest of the base 28 k's on both sides from n=50K-100K; 11 k's total.

With all sieving now complete on my base 22/27/28 reservation, once base 28 on both sides is at n=100K, I'll combine the other bases with it and test them all together up to n=150K followed by testing the one k that I mentioned up to n=200K. This will be a precursor to putting multiple bases in a PRPnet server in the future.

Reserving all k's on Riesel base 6 for a future PRPnet team drive.

I have the sieve file from Karsten and we're going to need some sieving done to get it up to where the Sierp side is at. That way, we'll be able to eventually combine the sieving with Sierp base 6. I'll set up a team sieve effort. I did some sieving to get it up to a nice round number.

Right now, we need to get Sierp base 6 up to n=150K that is currently on a PRPNet server. It's currently at n=~136K. Max, I ran the server for ~2 days on 2 cores but had to pull off to start the NPLB team sieving effort on 3 quads.

For the time being, we'd like to get the Riesel and Sierp sides up to the same level mainly for sieving efficiency purposes. I don't think it makes sense to combine the testing effort on both sides in the same PRPnet server due to the large disparity in k's remaining. Riesel base 6 may have a chance of being proven in the next 10 years. Sierp base 6 does not. When we start putting multiple bases in PRPnet servers, they should probably have a relatively equal # of k's remaining.

Karsten, thanks for your excellent effort on Riesel base 6 and providing us with your sieve file! :smile:

Sierp base 31 is now at n=11K. For n=10K-11K, 112 primes were found. 1822 k's remain. Still going to n=25K.

Riesel and Sierp base 28 are complete to n=100K. No primes found for n=50K-100K for all 11 k's remaining combined.

I am now doing some additional sieving on base 28 for n=100K-250K. More sieving is needed on this base and possibly another one before continuing on with bases 22/27/28 up to n=150K.

Ehh, yea.. almost forgot this thread.

I'm still alive - but this damn k don't want to die :(
Current status:
sierp-b17: one k remaining, n ~ 336K
sierp-b18: one k remaining, n ~ 260K

Great. I was getting close to asking you for a status.

We have many Sierp bases where one k remaining won't die.

Can you post your results files for these k's that you have so far? If they're too big to post here, you can Email them to me at: gbarnes017 at gmail dot com.

If these k's refuse to die, at some point, we'll want to double-check them.


Thanks,
Gary

[QUOTE=gd_barnes;165261]you can Email them to me[/QUOTE]
Done.
Did you receive the files?

Could you please recheck just one of the latest results? I overclocked my CPU a little bit. The prime stresstest says, everything is ok, but I think it is better to be sure :)
