Interesting.
I have removed both pairs from the results and prime_list tables. If someone can fire those two k&n pairs back into the queue we'll get a fresh look at them, or we can do them again by hand, I mean manually. ... can you imagine doing this by hand!? LOL OR throw the residuals at me, but hard enough to make sure they stick. :P 
[QUOTE=AMDave;290249]Interesting.
As requested I have removed both pairs from the results and prime_list tables. If someone can fire those two k&n pairs back into the queue we'll get a fresh look at them.[/QUOTE] That was quick. Thanks Dave. Hum. I just thought of something. Before we can run the corrected pairs into the DB, we need to get those pairs and primes deleted out of our PRPnet server, else it won't accept the corrected (i.e. duplicated from its perspective) pairs and the server prime/pair counts will be messed up. Unfortunately I'm out of town at the moment and will be back late Friday. Max, if you have a few minutes sometime before Friday to delete those bad pairs out of the server, that would be excellent. Please make sure that the primes are deleted also. If you can't get to it before then, we'll just have to wait for the full correction until sometime on Sat. Gary

Here is the list of pairs
I will redo them and send you the results so you have the correct residues. 
Tops. Saved to my desktop.

Okay, I've deleted the two problem primes from the PRPnet server's database and reinserted the respective candidates. They were promptly reassigned to two of Lennart's clients and should be returned within 10 minutes or so (composite, of course). I adjusted PRPnet's stats tallies appropriately as well. [I](Note: I adjusted the "primes found" counts for both PCZ and FreeDC but not the "tests performed" counts, since that would also involve messing with the points count and that would be a mess. Since he'll be retesting the same candidates manually on a stable machine, the stats will still be accurate in the end.)[/I]
As for the rest of the candidates tested by PCZ's unstable machine, those would be a bit more tricky to delete; I deleted the two primes from the PRPnet database individually, i.e. by typing in each candidate name specifically. This, of course, would be impractical for a long list of candidates; and it isn't really necessary anyway since we're redoing them manually, not through the PRPnet server. Since the redos for the bad results will be done by the same user as before, fixing them in the main stats database should be fairly easyonce he completes the tests, we run a diff to compare the old and new results, and whichever residuals are different we fix with: [I]update results set residual=[new] where k=[k] and n=[n];[/I] respectively for each corrected residuala MySQL script file with commands in the above format should be easy enough to whip up by a Perl script or the like. The end result will be that nothing changes except the residuals are now correct. The only thing this doesn't take into account is the raw text results files from which the DB initially loaded the resultsthose will still have the incorrect residuals in them. This isn't too big a deal since they'll already be fixed in the DB, but if we did ever have to reload the entire DB from the results files (say, if it was somehow lost), we'd end up with the incorrect residuals. Dave, how do you think we should handle this? 
Might be worth seeing if other results from the machine are affected before giving it too much thought. It is incredibly unlikely that two composite numbers would be found to be prime just from random residues.

[QUOTE=henryzz;290343]Might be worth seeing if other results from the machine are affected before giving it too much thought. It is incredibly unlikely that two composite numbers would be found to be prime just from random residues.[/QUOTE]
Yes, but I'm not sure if random residues are the sole factor in creating falsepositive results; while I will admit I don't have any mathematical basis for such a claim, empirically, there are a lot of false primes that have been turned up over time, far more than would be expected if it was just a random 0 residue. (There's a thread at CRUS from a while back where we calculated how many tests it would take to crank out a random composite residue containing a 9hexdigit string, and it was quite huge.) False primes seem to be a (somewhat) common type of bad result produced by unstable machines, so I'm thinking there must be something more to it that can "bias" the incorrect result toward positive in certain types of instability situations. 
[QUOTE=mdettweiler;290302]Dave, how do you think we should handle this?[/QUOTE]
I can pull them from the files, no problems, but I think we should see what results PCZ comes back with from the other machine before I make permanent changes to the results files. 
I think the NPLB server should automatically verify the primes found. If it is confirmed as prime then nothing happens, if it is confirmed as composite then the pair should go into the server to be tested again.

Wait for my results to come back. Could be that there were only the two false positives and the rest of the tests were OK. Haven't finished quite yet, but so far it doesn't look too bad. Another 12 hrs or so and they will be finished and the residues can be compared.

I just got a flurry of emails from the port 2000 server reporting an impossibly amazing run of primes by PCZ (14 in very short succession!)I'm assuming this is some kind of error? :huh:
Edit: Correction, make that 25 primesI missed 11 of them in my previous count. Also, I just got a handful of fresh ones in my inbox. Is this an unstable computer going completely bonkers or something? 
On a completely unrelated note, I have a prime of my own to report:

Max
One of my machines has indeed gone a bit bonkers. Fortunately it has only been running for a short time, around 6hrs. I can see that is has only tested 128 candidates or so but it reportied around 40% of them prime. Those pairs will be retested ASAP. It is my only Bulldozer PC and i am tempted to throw it down a deep dark hole. 
[QUOTE=PCZ;296711]It is my only Bulldozer PC and i am tempted to throw it down a deep dark hole.[/QUOTE]
nononono. please don't do that. Bulldozer needs the optimized client to handle the vectors, but it has bugs. We'll take this into email with Max and PCZ. 
Brian,
Can you provide a list of the bad primes here. We need to have Dave remove them from the DB. Thanks, Gary

List of bad pairs attached
I have these pairs being reprocessed on another machine so i can give you good residues. Will post them up in a few hours. 
Awesome. Thanks.
Ignore my email. These posts & the file covers it. Ta. Werkin. ed  done. I saved the patch just in case they come through again from the port db in the nightly batch. If that happens we'll get the emails again, but we'll know to ignore them. hehehehe. Lets see if Max can beat the clock. :D 
The results are coming through again from the port db again on the hourly batch.
So we got the notifications again. I need to leave these in the db until tomorrow when the port db won't send them through again. No probs. Only a few disoriented electrons. Nothing that can't be fixed :)

Ok i have retested the 128 pairs which the BD made a mess off.
Strangely the residues actually match. Well excluding where the BD decided to declare them prime. :( I would have expected the residues to be corrupt but it appears not. !!
