When corrupted results get validated...

<< < (5/21) > >>

perryjay:
Just checked my validation inconclusive and found three or four where my wingman turned in .01. I should be ok on most because the third wingmen are running on their CPUs. I followed out the .01 wingmen and all seem to be running either a 470 or 480. They are also getting a lot of .01 credit claims validated. Again, tracing out their wingmen, they are also running 470/480s. I wonder just how much we are missing because the third man turns in good also. :o

Of the Fermi cards (the first 8 in Claggy's list), seven are running the stock v6.09_cuda23 application.

And of the five additional Fermis that Claggy has listed, every one is running stock v6.09_cuda23.

Raistmer is absolutely right to say that there are two distinict problems:

1) Random state corruption of older cards
2) Fermi cards running incompatible applications

The point is, the second problem could be solved at a stroke by deploying the v6.10 Fermi app which has been tested - and has passed the test - at Beta.

That's an incredibly easy solution, and would reomove, on Claggy's figures, a hugely significant part of the problem.

The random failures would remain, to be dealt with as we understand the problem further. But that problem has existed for months, without reaching critical mass. If we remove the Fermi co-validators, it should remain insignificant: but the rise of the Fermi means we can't ingore problem #2 any longer.

Raistmer:
Sure, I though yesterday night project maintenance will bring 6.10 to SETI main, still not ?

Richard Haselgrove:
No sign of it. But something's going on: looking at Claggy's list, only one (djwhu, 5424576) is still blowing away significant numbers oi WUs - and incidentally confirming that mid-AR suffer the same fate. The latest addition (Aaron Danbury, 5373696) has done a few, but with the new work supply, it would normally have many more. So it seems that they may have put some sort of limiter into the system, but it's not obvious what.

David has got the message (off-list response), but hasn't got a reply from Eric yet.

And the problem is about to get worse - Fermi GTX 465s have landed in the shops, and are already being discounted: I was offered one for £215.99 in a mailshot. Won't interest the hard-core crunchers, but will certainly attract a few into the fit-and-forget segment.

It is to mention, I get no work for fermi application since yesterday.
All wu's are coming are for cpu only.

I think it is blocked till the situation is solved.
