I have what seems to me a lot of Pending credits on one of my machines because the work unit remains "Unsent" and so cannot achieve the minimum quorum necessary. And these units have remained "Unsent" for quite awhile!

Here are some examples:

319897
319961
322143
328067
327754

Thanks!

May I try to answer? Cosmology doesnt have that many users - 393 atm, many of them havent downloaded any of the available results/wu's...

So the answer might be simple: Because of low demand, the second result hasnt been sent yet.

Okay, its just a guess, but I'm sure a project official will answer if I'm wrong here!

Best regards, Steffen (aka Shai) :)

I would be very happy if that were the answer! :) Thank you, and let's hope it is true!

I think there is some problem with HR that is causing this. I've been seeing some results like that for some time. Recently, I set some of the oldest pending results to a higher priority than the others so that they'd be completed first, but the scheduler doesn't seem to want to give those results out. I've posted in the boinc_projects mailing list to see if anyone can give me any insight.

That could be part of the problem but it does seem strange that the WU's haven't been sent yet. I did some checking on the WU's that I've received recently and it seems like their sent out quite randomly or not.

Some of the WU's I have gotten have been Created as recently as today, and some of them are dated the 21'st of July, so eventually those WU's will probably be sent out again in due time ... :)

Thanks! And it is always nice to know we can consistently count on you to respond quickly to our posts regarding problems! :) I knew as soon as you "got into the office" this morning I would get a response! What else can be said other than that you are the best!

Oddly enough, the results from my other computer working on the project show none of the same problem. The "Unsent" work units problem seems limited to this on machine. That seems odd to me, but there you have it!

Hopefully these "Pending" "Unsent" units are helpful? If not, or if you already have enough data to diagnose the problem/issue, it might be prudent for me to detach that one machine from the project until things are straightened out? Thanks!

Further research shows that my AMD Athelon units that are successfully validated are only sent to other similar AMD Athelon computers! It appears you are sending units to be validated only on the same type of processor that the first unit is sent out to.

Thus, perhaps there are just a lack of AMD Athelon machines signed up for Cosmology@Home on which my units may be sent to be validated, and thus my completed units are sitting "Unsent" on your server!

Is there any practical solution to this so that these units are useful to you? The apparent lack of other AMD Athelon processors signed up for this project seems to be a problem (at least for me in obtaining credit, but more importantly for generating validated results for you!).

Thanks!

Similar problem here. A Linux computer. All large WUs since 20070724 are "pending" and "unsent".
With the Windows computer is all ok.
The Linux computer has now an unsent WU mixing from CAMB 1.24 and CAMB 1.25

I would think that a WU running on an Athlon and an Athlon xxxx+ should produce similar results. Or is the code "smart" enough to use different instructions if available? There are a lot of AMD 3800+ to 6000+ CPUs out there.

The Linux Pentium M (laptop) I could see being a problem. Up until recently it was a major piece of work to get Linux to run on most laptops.

And to add to this, I guess the core issue is that the oldest work units are not preferentially sent back out first to enable validation. Thus, the project will not get the older units validated for quite some time, which of course is not in the best interest of the project I would imagine?

And that agrees with your earlier post here that "the scheduler doesn't seem to want to give those results out." So hopefully a solution is forthcoming, that is the purpose of these beta tests isn't it? :)

...Any more would make it harder for me to figure out the problems with HR that we're currently experiencing.


Would I be safe in assuming that this problem includes the "Unsent" issue with the second set of work units which prevents validation of my AMD Athelon processor results? Thanks! :)

As far as I know, any Unsent would only be an issue with HR if an equal CPU/OS system can't be found for those results. Of course, strictly spoken there are no AMD Athelons, they have always been Athlons, but um, you get my drift.

Unsent only means they haven't been sent out to another system yet. In due time they will be.

Units like this one
and this one are older than a week and show no indication of being sent out for validation, so that is the issue, not whether there are other systems available to work on them (because a few newer units have been sent and validated!).

It's possible you have the only Athlon with Windows available. The thing with HR is, that such a result won't be sent to an Athlon running another OS, unless Scott allows that. And depending on how strict he set up the HR, they won't be sent to another AMD either.

Perhaps that he can allow the results to be resent to your Athlon. It's been done on other projects.

Well, actually, I just changed the HR class on all Athlons to be equivalent to Athlon XPs. I'm not sure why that didn't occur to me before.

I think the whole problem started when there was a lack of plain Athlon hosts. When I changed Athlons to be equivalent to Athlon XPs, it didn't change the HR class of the workunits that were already completed. Now that I've done that, things should be working again. *crosses fingers*
