S16 is complete to n=380K, nothing new found, continuing happily!
Leading edge is at n=380284 Estimate of 235 days remain according to PRPnet stat Currently 28780 tests is untested

Change of plans
Yesterday Lennart gave me an offer, that I could not restice. Lennart has offered to support the S16 effort from time to time. So in therefor I've now removed n>390K to n<=500K from my PRPnet server and it has been sent to Lennart and loaded to his PRPnet server. This means, that the range from n>390K to n<=500K will be done by KEP and Lennart. I expect no new primes for n<=390K, since only 510 tests remain for 18 k's. This also means, that I'm going to sent Gary alle the results that I have produced for n<=390K within the next 4 days. I do expect us to have some more primes for n<=500K, but we'll see. At least now the very old drive will be wrapped in less than 100 days in stead of up to 200 days Take care Kenneth |

S16 is complete to n=420K
All results for n>320K to n<=390K has been e-mailed to Gary. I expect Lennart to pull the data for n>390K from the PRPnet server and e-mail the range n>390K to n<=500K to Gary. Nothing new beside the 2 previously reported primes by Lennart has been found. So currently 19 k's remain for S16 overall and 16 k's remain in this drive. I expect us to find at least 1 more prime before n=500K and maybe even more, since this conjecture seems to be very primeproductive. Take care Kenneth |

Kenneth,
Two questions: Based on the Email that you sent me, would it make sense to have Lennart doublecheck n=380K-390K? Your Email made it sound like there could be some missing tests in this range. It looks like Lennart is testing all of n=390K-500K. Is that correct? If not, are you connecting to his PRPnet server? I'm a little unclear. Lennart, Congrats on the two new quick primes!

At your first question. The computer suffered a Harddrive I/O error and I had to recover my computer, using chkdsk in windows command line client and it is unclear to me if that can have had some effect to the PRPnet resultfile, such that some tests has more than 1 appearence in the datafile. Especially the PRPnet datafile is suspicious since I had more resultlines in the PRPnet resultfile than the PRPnet stat showed as total. I haven't compared the original input file, with the resultfile, since I'm not sure if everything on the harddrive is as should be after the use of chkdsk, so I haven't really gotten any idea weather or not everything is tested or something is missed. I'm convinced that everything should have been tested at least once, but the fact that I had more resultlines than total tests completed, gave me a bit of a concern that something could be wrong. That was why I asked for your kindness and do a comparing of the original input file with the resultfile, to see if all tests is at least appearing once in the resultfile I sent to you. I hoped that you might have a script that could do the job in stead of having to split up the datafiles and compare columns in a spreadsheet. Sorry in advance if that was wrongfully assumed In regards of doublechecking, I'll not say something for sure as to do it or not. A suggestion I can come up with must be to have 2 tests doublechecked for each set of n=10K and see if something looks bad. If something bad is found, then maybe the entire range for n=320K to n<=390K should be doublechecked. But weather or not to doublecheck, I'll leave it for you to see what you feel most comfy doing. On a sidenote, the only faulty thing on my computer crunching S16 is the HDD, but since I don't know chkdsk well enough, I can't give a guarantee that in fact the data are 100% valid, but they most likely are, according to what I could find around the internet googling I/O errors on HDD. Hope I got it all covered. Take care Kenneth |

It appears that we are now 3 users working on the n>390K to n<=500K range:
1. Lennart 2. KEP 3. John Don't know who John is, but like others he is very welcome. This will speed up the completion of the S16 tests remaining for n<=500K |

Kenneth,
Lennart has offered to doublecheck n=380K-390K. Can you send him the file for that range? I would feel better having it checked again. Thank you! Gary |
