Message 1152095 - Posted: 14 Sep 2011, 13:25:49 UTC

In switching a machines from a x64 OS to a x86 OS this morning. It would seem I left the <platform> tags out of the app_info.xml so it dumped all of the work. It is getting it all agian as resends. Only the MB work has extreamly large estimated run times. The AP tasks are estimated at 16 hrs which seems to be in line with the normal run time for the machine.

On the plus side the downloads are finished very quickly instead of sticking liek they have been recently. This will probably help everyone finish up their pending downloads and let the d/l servers rest a bit.

Message 1152142 - Posted: 14 Sep 2011, 16:01:34 UTC - in response to Message 1152088.  

I got a few WU's from 25jn11ab that estimated at 133 hours on my CPU. Final times were around 3 hours. That is an unusually long time for even a VLAR on my PC.
These WU's weren't marked as VLAR's either.

I have to wonder if the estimates are specific to the AR. So if BOINC sees an AR that it hasn't processed yet, It gives wildly exaggerated estimates

The estimates for all AR's were done a long time ago. See Estimates and deadlines This if I remember rightly was just after the Enhanced app was introduced, when there was only one receiver. But the same applies to MB (7 receivers with horizontal and vertical beams) which reduced the estimates to about 70% (probably it is 1/sqrt2%) of the enhanced estimates.

I can already see the fubar/unfubar process starting on my top rig.

I have a bunch of GPU work still in cache, so it works on them normally until the DCF or additional downloaded work with the fake completion times triggers it into doing tasks just downloaded. Then it crunches up a batch of the brand new work, readjusts the DCF, and goes back to normal crunching.

It's kinda fun watching a task with an hour twenty estimated completion time zip through in a little over 2 minutes.

I can only imagine what Boinc is thinking........

I just hope Boinc figures it out before the ol' cache gets too thin.

I notice that the new increased runtime WUs are maked as 6.09 (cuda23) whereas before they were all 6.10 (cuda_fermi).



EDIT- *scratches head*
At least that's the case on one machine, on the other they're still 6.10 (cuda_fermi).
Will have a closer look later on when i'm awake.

In a strange way, this has worked out great..

It has cleared the backlog(at least temporarily) where I can actually GET some gpu work!!

I've got an astropulse with a 175hr estimate and a multibeam with a 15hr estimate. A few more of those and there goes my cache :(.

Cache?

My AP jumped from ~17 hours to almost 9 days. That means where I used to have ~22 to 24 tasks I will now have 1 or 2.

Not very promising.

When did you guys down these AP tasks? The ones I got before 14:00 UTC had my normal estimates.

I got the astropulse with the whacky time estimate 14 Sep 2011 | 9:49:30 UTC. The astropulse before it with a normal estimate I got 10 Sep 2011 | 11:49:59 UTC.

Anything you do to try to correct the situation could turn out unwise if Dr. Anderson recognizes the problem and does some corrective modification. Sitting tight and hoping for the best might indeed be the best policy, as Geek@Play advises.

Dave was informed that the new changeset destroyed the well working estimated times of app_info.xml users and soon he will release a fix?

That is great news.

Let's hope he fixes it sooner than later, before more machines get more screwed up.

No, this was a question of me.. ;-)


BTW, I'm confused that this new changeset wasn't tested before at S@h Beta Test.

Well, I am seeing a bit of a chink in the Cricket graph already.....
Looks like the bogus completion estimates may be fooling most of the Boincs on the project that their computers don't need any more work.

Does anyone know if these estimates are going to fix themselves? Is this going to be like when we first start running an app and have to wait for 10 validations before times fix?

Joe's post (the 2nd one in this thread) seems to indicate that Boinc will self adjust for it eventually, but I think the adjustment will be in the local Boinc installation, not server side.

Which to me indicates that things will be screwed totally for any rig which still has work cached before the change was put into place.
And then, it will be a slower process of adjustment. Not simply completing and reporting 10 valiated WUs.

That's my take on it.

I suspect that Joe will chime in again if my understanding of it is wrong.
