I'll reserve this to n=200000.

Although sieved to 2e12, it didn't appear to be sieved deeply enough as there were over 1500 candidates left. I restarted sieving, but didn't find any factors after a while, which I thought was odd. I thought that maybe the depth was incorrect, so out of curiosity, I restarted the entire range. I discovered that the whomever sieved originally must have used either newpgen or a buggy version of srsieve/sr2sieve because I'm finding factors of n for p<2e12 that were missed previously. Fortunately it should take about two days to get back to 2e12. I can then evaluate to determine if I need to sieve deeper. I'll provide more information once it gets to 2e12.

[QUOTE=firejuggler;288349]here is R631, k between2 and 50k[/QUOTE]

With a max prime of n=2355, I assume that your search depth on all k's was n=2500. Is that correct?

This doesn't really help the project in any measurable way because the conjecture is k>149M. I'll keep it stored on my machine in case anyone wants to search the entire thing at some point. My suggestion is to focus on bases with conjectures k<100K where you can search all k's to n=25K. There are still many that have not been started with conjectures 10K<k<100K.

You had not previously reported a status so you found a lot more primes than that! There were 209 primes found for n=10K-25K so...

To be more specific for balancing purposes:

For R555:
500 k's remained at n=10K
136 k's were found prime for n=10K-25K
364 k's remain at n=25K

For S555:
277 k's remained at n=10K
73 k's were found prime for n=10K-25K
204 k's remain at n=25K

In the future when doing both sides of the same base, please report and send primes and k's remaining split up between Riesel and Sierp. It took me a while to split them all up and balance them. Thanks.

Status and reservation for S998
 

S998 is currently testing at a trailing edge of n=188K and a leading edge of n=189K. I'm going to extend my reservation for S998 to n=400K. There is, before sieving to p=500T a total of 4020 tests remaining in the range from n=200K to n=400K. However when I complete S998 to n=200K, I'll sieve from p=136T to p=500T and hopefully remove several hundred candidates.

ETA for wrapping S998 to n=200K is April 3rd 2012, on my new Sandy Bridge.

Take care

[URL]http://www.noprimeleftbehind.net/crus/sieve-sierp-base991-25K-100K.txt[/URL] is the only sieve file available I think. While there is no LLR work done it does not make much sense to sieve further, so the sieve file stays up to date until somebody has done some testing.

n=25k to 30k shouldn't be too bad. We'll see.

Hi pokerspeed,

Welcome to CRUS! To add to what Peter said, sieve files for many of our bases can be found on our main reservations pages at [URL="http://www.noprimeleftbehind.net/crus/Riesel-conjecture-reserves.htm"]Riesel reservations[/URL] or [URL="http://www.noprimeleftbehind.net/crus/Sierp-conjecture-reserves.htm"]Sierp reservations[/URL]. Just go down to your preferred base and if there is a sieve file, it will be out to the far right.

Good luck!

I'm wondering, what is an average turnaround time for a range of work? I can't always be at the computer to set it and let it run (electric bill, always high) but I want to do the work in good time.

Oh - secondly, would it be easier if I set up a LLR/PRPnet server on one of my computers to host all the files and distribute the pairs, or is doing it manually a tad easier? Both computers are in the same house and are networked via wireless.

To use PRPNet, the hardest part is installing MySQL or PostgreSQL. Once done, the rest is easy. With multiple computers/cores, it is easier than manually monitoring the clients.

Thanks for the speedy reply.

I've been hunting around on the internet for a little while and I've struggled to find the server package for PRPnet or LLRnet. Do you have a spare copy lying around that I could procure, or do you have a link to one that you could give me please? I'm eager to start this work.

Thank you Batalov. Time to set this puppy up and get the work flowing.

EDIT: This isn't exactly something you can blitz through like a whirling dervish - the complicated dependencies and database setup at the command line is confusing at best. Will it work if I use the OpenOffice connector? It supports ODBC so I don't see why not.

Speed is not an issue here. Except for the team efforts (e.g. R6 / S6) where long turnaround times might (not very probably) result in unnecessary work being done by others. Apart from that, take your time. There are reservations which have been running for months, years even. Just let Gary know you're still working at it every once in a while. I think he'll ask for a status update when people have been silent for three months or so.
