[QUOTE=paleseptember;218618]Nice work rogue! I'm in awe at the work that you're putting in. You're putting my efforts with R603 (currently at ~19K) and S928 (at 12.8K) to shame![/QUOTE]
It isn't as much work as you might think. I use the script, then sieve, then put the .pfgw file into PRPNet. I kept doing that until I had an estimated ten days of work. It turned out to be about four days of work.

Probably only knock off a small percentage though.[/QUOTE] It has already been suggested that a public PRPNet server be set up. The sieving effort would need to be coordinated. Right now I'm on a mission to knock off all conjectures with k < 100 because those conjectures are going to add a number of new single k remaining conjectures to the list.

Probably only knock off a small percentage though.[/quote] I like the 1kers. They are great. I like the idea, originally suggested by Mark, of having one big PRPnet server where we continually load in new sieved files for new 1k bases. (We could even have 2 or 3 PRPnet servers where one has 1k bases, another has 2k's thru 5k's remaining bases, etc.) My current thinking is to sieve all unreserved 1k bases <=250 that are at n=100K, which there are now a lot of because Max and I have been working towards that on both sides (mostly Max in the last 2 months). We have 3 to go. But before we can begin sieving all of them from n=100K, we need to test some 2k and 3k bases that are at n<=100K to see if we can add some more 1k bases. I think Max has in mind to do those next. If not, I will. So it will be a little while yet. The idea is to maximize the # of 1k bases that we have at n=100K. It's the large number of new bases, especially the ones with small CK, that I don't like. That's why Ian has offered to do the admin work on all new bases with a CK <= 200, an offer I gladly took him up on. I'm on a business trip until early Weds. and he is keeping a running backlog of them, something I could in no way do previously with the current load of them coming through while out of town. He immediately updates the 1k and untested threads with them and then sends me the HTML for them 10 bases at a time. I've only had time to add 2 batches of 10 bases to the pages while gone for a week and will get to the last one on Weds. But I know he probably has about 3050 more of them that he'll send me 10 at a time, which I'll be able to get to about once a day after I'm back. Now it takes me about 25 mins. per small base. I can usually paste in the HTML to update the pages and do spot checks for a batch of 10 in < 1/2 hour. Previously it took about 3 times that due to all of the other stuff needed plus I found that I could not keep an accurate backlog of them so I was continually going back and finding ones that I missed.

I assume you mean the 1k on R636 since S636 is already proven.

As usual, I'm concentrating on the higher end of the spectrum. I'm working the bases > 250 trying to get them to n=100K. I realized my strategy of doing them to n=50K and then to 100K was a logistical nightmare so I'll start doing them from n=25K to 100K. Meet you guys somewhere in the middle.
I also have those 12 bases < 250 (actually 1 is S252) that I'm taking to n=200K. 9 of those have 1k left. 2 have 3 k's remaining and the last has 2k's. I should have those finished in < 2 months.

R636 tested to 50k and released.

Slightly strange situation, any advice would be helpful.
I'm taking R603 to n=25K, and checked in on the pfgw.out file and pfgw.log files. pfgw.out hasn't been updated in about a fortnight, and despite pfgw grinding through the file, no results are being recorded. The pfgw.out file is 4,060,606 bytes (I have no idea if there is a maximum filesize, after which is chokes.) I have stopped and restarted, moved the pfgw.out file away in an attempt to get it to start a new file afresh, to no effect. So, should I go back and start fresh from the last line recorded in the pfgw.out file, or trust that it will have recorded the prps to pfgw.log. (There are primes in that file that are past the cutoff from pfgw.out.) Thanks in advance. EDIT: I have stopped and restarted, and it appears to be happy again. However, I'm now missing residues and results for approx n=17K to n=21K. Should I rerun that segment?

Thanks in advance. EDIT: I have stopped and restarted, and it appears to be happy again. However, I'm now missing residues and results for approx n=17K to n=21K. Should I rerun that segment?[/quote] Very odd. I wonder if it is a hard drive problem. I would suggest backing up all your files before doing much more on the machine. I would definitely rerun that range. There could have been some primes in there. If it wasn't writing to pfgw.out then it might not have written a prime to pfgw.log. Rerun it by making a copy of your sieve file, change it to a different name, and remove the lines at the beginning that are already processed. Keep in mind that it won't remember which k's had primes. To have it not process those, you can do 1 of these 2 things: 1. Use srfile to remove the primed k's from the copied sieve file. 2. Manually write all the primes at the beginning of your copied sieve file. It will find them prime again and so won't search the k's anymore. You'll just need to remove the duplicated primes from pfgw.log when you are done. I find it easier to do #2, especially if the sieve file is big or there are a lot of primes. Gary 
Is your filesystem FAT32? I believe that there is a 4Gb file size limit there. Change to NTFS and the problem would be solved.

Working with Mathew Steine, I moved the pfgw.out file away completely, and told it to restart, which worked this time.
Rogue: I think I was running f0 l switches, but I could be mistaken. That's my standard MO, but I've been known to do daft things previously. I'll return to n=17K (ish), and start from there again. Bah! Two weeks wasted effort :P Thanks for the suggestions Gary, Rogue, Henryzzz (and Mathew via PMs)

Nice. That proves both sides of base 1011 with a conjecture of 208. That's the highest proven conjecture for bases > 811 on the Riesel side and for bases > 666 on the Sierp side.

S530 is complete to n=25K; 3 k's remaining; base released.
S707 is complete to n=25K; only k=26 & 40 remaining; base released. S731 is complete to n=25K; only k=28 remaining; base released. S870 is complete to n=25K; only k=38 remaining; base released. No primes found for n=5K25K for any of the bases. :( 
I've done some smallconjecture testing on some bases that had 1 or 2 k's remaining at n=5K the last 23 days. Here is what was done:
R533 with CK=88 has only k=74 remaining; highest prime 56*533^8981 S528 with CK=116 is proven; highest prime 64*528^10186+1 S550 with CK=115 has only k=94 remaining; highest prime 75*550^5841+1 S701 with CK=92 has only k=52 remaining; highest prime 12*701^969+1 Note the mostly extremely small highest primes. Only 2 primes were found for all 6 bases for n=5K25K including 2 bases in the 251500 thread. That's 2 primes found in that range for the last 10 bases that I have tested. :( Oh well, a lot more 1kers for Ian! :) All have been tested to n=25K or until proven and are released. [B]New reservations:[/B] [B]R530 & S552 to n=25K.[/B] 
S552 with CK=78 is proven; highest prime 26*552^22956+1
R805 with CK=92 is proven; highest prime 90*805^22121 After finding only a total of two n=5K25K primes in 10 bases with this small effort that I've been working on, S552 had 2 primes n>5K itself for the proof. On R805, I was surprised that there were any bases left with CK<100 that could be proven by n=2500. I can now say that there are none left that can be proven by n=1K. Some of them I'm taking to n=5K and will reserve if they have <= 2 k's remaining at that point. I'm clearing out a little bit of fluff and evening up the sides a little before going out of town next week.

I just missed this one (and a couple of others with lower conjectured k). 
Sierp 582
Sierp 582, the last k, tested n=25K100K. Nothing found.
Results emailed. Base released Reserving more 1k's to n=100K: S635, S643, S650, S677, S679 
Reserving S619, S622, S669, and R875 to n=25K.
All have either 1 or 2 k's remaining at n=5K so I'll probably have more 1kers to add later on. :smile: This will officially finish testing all CK<100 bases that have either 1 or 2 k's remaining at n=1K. There are quite a few that have 3 remaining at n=1K that could easily drop to 1 or 2 remaining by n=5K or even be lucky enough to be proven. But this effort just takes too much admin effort so I won't be testing many of those and may not test any at all.
