Any indications of errors in your log files? If so, I'll take them and check interim results like last time, but if your runs were routine, then I'll leave them to Madpoo. He usually picks up triple checks within 24 hours (unless the anonymous churners get them first, but these exponents are far outside of the churn zone).

I have to be a little more parsimonious these days, because spot prices for c4.large have been edging up steadily from around 1.3 cents an hour a month ago to 1.7 cents now. Can't wait for the c5's to finally arrive.

The first-test machines in question have only a limited track record of results verified good or bad, but they might end up being in a grey zone where the error rate is way above average but still too low to justify systematically running DCs on everything. Those are the most frustrating kind.

Good point - yes, all 3 of the above runs had a mix of expected (because close to the 3072K exponent limit) of ROEs up to 0.4375, plus at least a dozen of the catastrophic-ROE-followed-by-successful-interval-retry of the kind I spotted in my first runs on the Ryzen. Far fewer of the latter since David installed a water cooler on the system, and note the matching DCs in the same latest-batch had similar occurrences.

p.s. @Gord: If you do queue any of the 3 up, please make sure res64-printing is enabled for some multiple of 10Kiters, if possible - we can cross-check the every-1M-Res64s to check for divergences. Here are my 1Miter Res64 excerpt files:

 2017-07-03, 19:15 #1512 Madpoo Serpentine Vermin Jar     Jul 2014 2·5·7·47 Posts Unknowns... Here's a list of top 100 "unknowns"... by that, I mean it's the smallest available exponent for any machine with no bad or good results yet, and I ordered the list in descending order of the # of unknown tests they've submitted. I already skimmed the top 96 from the list for myself and these are the next 100. It goes without saying (but I will anyway) that these exponents are very likely to match, but there's just no way of knowing until we do a DC for each CPU. Out of this list of 100 (and the 96 I took) I expect there'll be 6-10 mismatches, but then that gives us an opportunity to more closely examine those particular CPUs and the rest of their unknown results. Enjoy.

Probably just a refresh. I guess people weren't interested. I also prefer doing the double checks that are more likely to have been done wrong the first time... this list, not so much, but it's the best way of making sure these unknown system were okay or not.

I did come up with a slightly different approach for dealing with CPUs with no real track record, and that is to look at the track record of the user. If they have multiple computers then the track record of one won't really indicate how the other is doing (Curtis Cooper is a great example...some are rock solid, some are fluffy marshmallows). But there are times when it's the same computer but they reinstalled the OS or upgraded or whatever which in the data makes it look like a new machine.

If a user has generated a bunch of bad results and here's another of their systems with no record, that's a better candidate for checking a few out than just a random sample, I'm guessing.

I need to refine that process a bit though and then I'll create some lists using that method.

I took the last one in your list. Just to ease your mind, I just completed a different DC and the residue matched exactly.

I seem to remember something here about a different work type number and the criteria for anyone being able to do that work. Perhaps you could go that way. Just a thought.

Thanks, Gord - I note that none of my current batch of 8 DCs on the Ryzen has emitted any of the worrisome instant-fatal-ROE-followed-by-iteration-interval-retrys that afflicted my 3 runs above - hopefully that also implies that the system flakiness that seems to have hosed my run of at least the first of the above trio is no longer occurring. 4 of the current 8 ongoing runs will finish in the coming week, will alert if any mismatch the previous submission(s) for those.

 2017-07-16, 05:24 #1518 Madpoo Serpentine Vermin Jar     Jul 2014 2×5×7×47 Posts Here's a list of "unknowns" For this, I looked at systems with no bad or good, but the user has more bad than good as an aggregate across all their systems. There weren't many like that, just 45 systems. These are the smallest available exponents from each of those along with the total # of unknowns they have so far. Even if there's only a single unknown (and this exponent is it), I figure there's at least a so-so chance it'll be done wrong if the user has a pretty poor track record anyway. Enjoy!
