Taking 217592. In case you are wondering I have a number of PCs without Internet access. This one appears to be beyond LLRNet limits for a while, so it shouldn't cause any problems.

For my current status, this is the current breakdown for my k:
390000 < 1
350000 < 2 < 370000
300000 < 2 < 320000
250000 < 1 < 270000
200000 < 1 < 210000
150000 < 2 < 180000
1 < 150000

The ones < 200000 are very dense, so it will be a while before they hit 200000, unless they find a prime before then. As for the rest of the k I have reserved, I have been completely stumped. :down: I think that I have spent over 6 Ghz/years on these k.

If I release any of these k before finding a prime, I will report the residues.

rogue,

Are you using srsieve to sieve just your reservations? I'm getting good sieving speeds (125000 p/sec) on my slowest machines (650 Mhz) using a file with only my 6 candidates. If you're not already doing this, it might be worthwhile to devote one or more of your slower machines to sieving just the candidates you have reserved.

No, I hadn't considered that.

Isn't our combined sieving speed faster then that? On _all_ candidates.
(I get 60000 p/sec alone, combined I have no idea what we are doing, but I'm sure it's more then double that)

So downloading the sr5data.txt file, and filtering out your candidates might be more efficient.

Unless of course, you already have sieved out far ahead of the combined sieve.
And unless I'm missing something here too :>

Moved out the posts from reservation thread.

I would suggest that you send the residues regardless. We'll setup the stats, prime or no prime :wink:

I can do that.

BTW, sieving was marginally better than PRP testing, but not enough for me to spend a lot of time on it. I estimated that it would remove at about twice the speed of PRP testing, although I didn't run it for a number of hours to verify that result. I only ran it for about 15 minutes.

One more thing, I do take the .dat file every week or so and extract a file for each k and update each LLR instance, so I am still taking advantage of every else's sieving efforts.

axn 2006-10-03 23:27

Oh, and one more thing. If you are doing your own sieving, don't forget to send in the factors also. Otherwise we'll have holes lying around :smile:

To whom do I mail the residues?

Same as the one used for regular sieving.
