Even if only pfgw'd to 1k, manual intervention is not very needed, the large bulk of k's is already removed. Each k left will be an hour extra work though, so I remove as much as possible.

To make up for past reservations wich I either abandoned or gave up on, I've decided to give something back. Therefor I'm reserving: Sierp base 3 k>50M < k < 100M to n<=100000. Thanks for understanding. A total of 220 k's is held in the range
Also regarding Riesel base 3 k<=500M, a local power outtage has made it impossible for me to complete the range, since I can't get srfile to remove the k's already primed from the input file. If anyone would like to overtake and try to complete my incomplete work, please feel free to ask for the 25 incomplete ranges and I'll send them to you. But for now, consider it no option for me to do anything further on this Riesel range. Actually I'm getting kind of fedup with those riesel numbers, they are more difficult than the sierpinski numbers, so in the future only expect me to work on Sierp numbers if ever going to work on anything after this reservation is completed. Take care KEP

We were planning on running a team drive on that nrange that would run the same time as a team drive on the Riesel k=050M range. I guess the Riesel range is out now. KEP, please reserve a smaller range that you absolutely KNOW that you can complete. See what Michaf is doing where he reserves a range, finishes it in a few days, then reserves another, etc. Suggestion: Reserve k=50M60M up to n=100K. Finish that. Reserve k=60M70M to n=100K, etc. until you're ready to move on to something else. Thanks. Why is Riesel base 3 more difficult than Sierp base 3? They're basically one and the same as far as searching for and finding primes. Riesel has a lower conjecture so it should be ultimately easier. The chance of finding primes on either side is going to be nearly identical. I don't understand your reasoning. Why would a local power outage make it to where you can't run srfile to remove k's with primes? If you can't run srfile, then you certainly couldn't run srsieve and LLR on SIERP base 3 for the range you are wanting to reserve. Once again, your logic baffles me. No need to answer the last two paragraphs as I was just pointing out a logic flaw but please respond to the paragraph asking you to reduce your reservation. Gary

Reserving for Sierpinski base 3 k>100M to k<=200M. Sieving is already in progress and will continue. Reservation is made with consideration that you would like to make a TEAM drive on the k>50M to k<=100M. So my reservation is for k>100M to k<=200M for n<=100K. As we speak the 417 candidates has less than 877,000 k/n pairs remaining in the sieve file.

This is too much again! Here is what I already have you down for: 1. Riesel base 3 for k=100M500M to n=25K. I believe you still have a lot of work on that. You completed k<100M to n=25K a week ago and I just now started verifying that. Good work! 2. Sierp base 19 all k's to n=25K. Your status in an Email 3 days ago reported that you were at n=14.2K. This will likely take you at least another month at the rate that you currently progressing as shown in your Emails. 3. Sierp base 252 k=27 to n=100K. Currently at n=51K. A lot of work to get to n=100K! All of these efforts have a lot of work remaining. Please finish at least one of them before reserving any more work unless you plan on purchasing several more quads in the near future. k=100M200M to n=100M is a VERY big effort to take on by yourself. I would appreciate it if you'd let us run team efforts on the n>25K ranges. If you'd like to help us by sieving the range and then providing the file to us, that's fine but I'd really prefer that you dedicate your resources towards your existing reservations. As I've asked many times, PLEASE reserve smaller efforts. It makes it hard to administer when people reserve things, search part of them, and then stop in the middle of them.

Let me know what you decide, but for now sieving is stopped. KEP!

OK, for now I'll reserve sieving only to you on k=100M200M for Sierp base 3. Gary Last fiddled with by gd_barnes on 20100516 at 08:28 Reason: remove bases > 3

Reserving Sierpinski base 3:
k>50M to k<=100M for n>25K to n<=100K, sieving only. I'll sieve this range to the same sieve depth ~16G as the K>100M to k<=200M range. Once both ranges is sieved to the same depth, I will in respect of efficiency, combine both ranges and sieve the k>50M to k<=200M range in 1 file in stead of 2 files I expect the completion date to be only delayed by 23 days. Hope its OK, and that no one else has reserved that range for sieving KEP!

Sierp base 3 k=50100M ~53G (1 k per ~24 sec) Again I ask you to accept my appologize, it all refers to private reasons, and a matter of concentration aswell memory. Expect no more reservations (or at least just ignore them) within the next 6 months, since my intention is to wrap what is now reserved and then leave for at least a while. Thanks for understanding, and good luck on your own challenges Last fiddled with by gd_barnes on 20100118 at 09:01 Reason: remove bases not Sierp base 3

Reserving k=200M+2 to k=300M
Doing it this way: 1. Strict tests to n=2500 2. Sieve remaining candidates from n=2501 to n=25000 3. PRP test remaining k/n pairs untill n=25000 4. Verify the PRPs 5. Find the final remaining k's These 5 steps is meant as timings in order for me to find the best way to tackle a several G range for Sierp base 3. Also only very few PRPs should be composite if ever anyone, since I'm going to sieve pretty high the remaining candidates. Now a final question, how and which primes do I send? And to who should the desired primes be sent? Regards KEP Last fiddled with by KEP on 20081229 at 17:41

1. All primes > 1000 or > 500; take your choice. 2. All k's remaining at n=25K. I would prefer if you didn't remove k's that are multiples of the base. Although if you would like to, after you have tested to n=2500, forward me the k's remaining that are MOB that you think you should remove and I'll check them. In a synopsis for MOB on this base: Remove k's that are MOB if k+1 is composite. I think you are going to have a lot of work reserved again. Can you give me a list of your reservations? Thanks, Gary
