I don't think a broad statement would fit what I'm seeing.

Here's the same puter with new wus added. There was another VLAR added.

The first shows the result ID and both claimed credit/hour and granted credit/hour. The second shows Runtime, and the third show Granted Credit. These are the same wus shown in the same order(angle range ascending).

@ Tony, WinterKnight:

If there is a shortage of information about the crunching behaviour of these VLARs, I'd be happy to join in the data-gathering team. I accept the groundrules are: reputable FLOP-reporting and non-calibrating core client and standard science app [which rules my machines out - I run Chicken - but I can pull data off the site]. Any particular chip and/or OS you'd like me to focus on? And Tony - if you could email me a copy of your spreadsheet, it would save setting-up time! initial dot surname at btinternet dot com

With the long crunch times, at least these WUs aren't getting purged very quickly. Here's a sample I can get back to quickly:

Yep...It does seem a little more random than I first thought. Too tired at the moment to take it all in though. (Toddler in the household)

I've gotten a few more VLARs of various lengths. It looks like they all are in the "moderately slow" category compared to the average unit. The fastest ones are the shortest-to-crunch, in general, with the longest angle ranges. The worst are the 0.7 to 1.0 degree and the average ones are the 0.39 ones. Basis is credits per hour. But I've noticed that some "half-hour" units give less credits per hour, even for identical angle ranges.

The highest credit I've gotten so far is a WU valued at 88.15 and so far of the 4 users 3 are using v5 (5.2.13, 5.4.11 & 5.5.0) Boinc client software, I have no idea what the 4th user is using yet of course.

I agree that the 0.7 to 1.0 are worst possibly, my results from Beta just before it was released here on main site are shown here

Check this one out:
My machine claimed 94.73
Another machine claimed a lot less, but had an error
A third machine has claimed 175.69

OMG!

I wonder how Berkeley will resolve this one in terms of how much credit will get awarded?

I suppose it will depend on the third valid result, and a canonical result will be taken as the middle value?

I'd like to join too, but my cruncher (notebook) is running at varying speed, thus disqualifying itself as a non-reputable FLOP-reporting source. I just recalled I stored once a rare VLAR with AR=00700245, lower than these in Tony's data set. I can send it per email for recrunching if interested.

Thanks, Peter. I think there are two parts to the VLAR question.

1) Does the splitter/scheduler predict the crunch times accurately, or does it get it wrong, messing up cache sizes/deadlines/DCF for future WUs etc.? I think it gets it wrong.

2) Does the credit claim, based on reported FLOPs, make sense when put alongside the time spent crunching? It seems to me that the claims seem low, but whether this is because of difficult FLOPs (eg more divisions than usual), mis-counting FLOPs, a bug in code wasting time on something other than countable FLOPs, or anything else, I don't yet have a view.

Your variable speed would make it difficult to gather data re (1), but you might still be able to count a few FLOPs for us!

I've had a few email contacts off-board with Tony and others, and I've said I'm willing to help gather (and coordinate) data if it would help. However, I'm still waiting to hear if the project views this as an issue important enough to devote scarce programming time to, or whether it's just a minor oddity they can live with while they get on with more important matters. I would be reluctant to spend a lot of my time gathering data without some positive indication that it would be a help [rather than a nuisance!] to Berkeley.

Yes, it would still be possible to gather at least the FLOPS/AR ratios with my mentioned host. Originally I was not thinking about this possibility, as we were then, few months ago on Beta, trying to find the AR/time/FLOPS/CC ratio for various HW and app versions.

I just completed one of those ULAR's (0.007), and they definitely seem to score lower on the credit/hr. than the VLAR's. Looks to be about the same as the VHAR's for the machine that ran it.

I'll let you know when this WU finally gets validated! lol

My machine claimed 94.73 (Quite a bit less than you)
Another machine claimed a lot less, but had an error
A third machine has claimed 175.69 (HEAPS more than yours, but once a canonical result has been determined, it could be closer to the amount claimed by my machine)

LOL, most of mine are "Old Timers", but they do all right for themselves. ;-)

You must be crunching part time or else keeping that Opty busy doing other stuff. You might want to give it some of Simon's "Chicken Soup" though. Mostly likely the optimized app would knock a healthy chunk off those crunch times. :-)
