Got what I hope is a fairly straight forward question. Over the last week or so, I've noticed the RAC on my account auguring straight in toward Mother Earth. Not a normal dip, but a case of "We're going in !" So I looked at my account. I see a total of 1468 tasks In Progress, of which 578 are Validation Pending (this seems very excessive to me), 181 Validation Pending (also high ?), 287 Valid, with 79 Invalid and 6 Error.

I'm not familiar enough with what exactly those terms indicate, and frankly don't look often enough to see if these numbers seem normal or not. My main cruncher is an old i7 920 with two 460 SE's doing the GPU tasks, so not exactly state of the art.

Any help explaining the terms might give me a clue as to where to look for any errors, in they event they exist.

Much appreciated

You high numbers are because your GTX460 v2 is throwing a lot of overflows.

Check its temps, it maybe running to hot.

Cheers.

From what I can see, Looks like one of the cards may be overheating, needing the dust bunnies cleaned out, or similar attention. It shows in the invalid tasks results as device 1, but resides in PCI bus 2, though that order depends on a lot of things, so your guess which card.

Validation Pending: waiting for wingman, or Inconclusive - Didn't agree with wingman's result, would be either your or their 'fault'. Much higher than normal probably indicates a problem your end.

Invalid: usually indicates the task was sent out again, but yours didn't match that either. On a solidly functioning Cuda system with modern apps, this should be at zero barring rare events like cosmic ray strikes flipping bits and things.

Error: the task errored out (for a multitude of possible reasons, either end). Ideally should also be zero, though in the case of your 6 errors, they possibly look like tasks that either weren't received by your host, or were somehow lost by the server. Unless of course you still have them & just are taking several months to process them.

Thanks for the ideas guys, clearing the bunnies as we speak, actually had a can of air just waiting to be used. Now, if someone could just generate some heat here, the garage is freezing

Are you overclocking? Clock rates look high for those cards.

From one of the invalid results:

setiathome_CUDA: Found 2 CUDA device(s):
Device 1: GeForce GTX 460 v2, 1024 MiB, regsPerBlock 32768
computeCap 2.1, multiProcs 7
pciBusID = 2, pciSlotID = 0
clockRate = 1730 MHz
Device 2: GeForce GTX 460 v2, 1024 MiB, regsPerBlock 32768
computeCap 2.1, multiProcs 7
pciBusID = 1, pciSlotID = 0
clockRate = 1730 MHz

Edit: looks like the v2 version is clocked higher than I thought at 1556, so the higher rate may just be a boost speed from the driver you're using. Sorry, I thought the base rate was lower:
