Using CUDA device #0 "GeForce GTX 260" (806.98 GFLOPS)
WT* is that. no offense, but I'm very hesitate to believe those numbers...
holmis's reports 300 gflops as well, is the app mis-reading the gflop number?????????????????????
Reported five tasks on host 1001564 - two validated so far, three pending. Times all very close to 6 hours, no significant change from 3.07cuda.
Card is a 9800GT, stock speed, rated at 60 BOINC GFlops, but reported here as 508.03 NVidia marketing GFlops (as also shown in the GPUGrid FAQ). I've commented before that there's a factor of 8 or 9 between 'marketing' and 'crunching' GFlops - it doesn't matter which you use for card comparison purposes, so long as you always state which units you're using, and don't mix them.
Ok,
now I´m getting also work for the two remaining cpu cores.
@tjreuter: The 9800GX2 has two chips (2x8800GTS if I´m correct). It´s SLI on one card.
I like that cuda stuff ;)

Hi Hotze,
Off course that card has 2 processors, I was thinking at SLI and then they work as one.
If you like cuda you could take a look at GPUGRID, for about 7 hours work you can get 4000-5000 credits.
Is there "pure" CUDA-application is in developer's plans?
Yes. However, some part of the app will still run on the CPU - it'll never be "pure". We aim to reduce the amount of work done on the CPU as much as we can of course.

what are the specs of that card?????
MHZ?
the damn card better be; Liquid cooled, running at 800 mhz....
please post the message logs of the boinc start-up...
ok, nvm; i'll admit i'm quick to jump to conclusions....

No, it's not. You need to know that this value is computed by the device properties and not determined by benchmarks. It's the card's theoretical maximum performance which can be computed like this: number of multiprocessors * number of cores/multiprocessor * clock rate * flop/core/cycle. For your GTX 260 that's 24 * 8 * 1.4 GHz * 3. By the way, is this an overclocked card? Usually they "only" run at 1.3 GHz...
No one claimed that either your card or any given application could realistically achieve that performance ;-) As always, you may relatively compare different cards using the same measure, despite the absolute values not being very informative.

And we imagine that the GPU will continue to improve in the speed of processing as well, which of course will yield even more efficiency! :)

Card is a 9800GT, stock speed, rated at 60 BOINC GFlops, but reported here as 508.03 NVidia marketing GFlops (as also shown in the GPUGrid FAQ). I've commented before that there's a factor of 8 or 9 between 'marketing' and 'crunching' GFlops - it doesn't matter which you use for card comparison purposes, so long as you always state which units you're using, and don't mix them.
Ah, so that's why. So 1 BGFlop ~= 8 NVMGFlops
[aside]
Reminiscent of :
- the 1 MB vs 1 million bytes issue ( and GB .... )
- the Cyrix processor's 'Performance Rated' speed ( 'as good as a Pentium' vs actual )
- the quoting of CD drive speeds ( angular or linear velocity? )

BOINC is telling us a much lower figure. This is funny because when you put a ATI card in with it their cards are reported as being much faster (by BOINC) under 6.10.0. While there is differenced between the cards the formula needs to be standardised, at least in the BOINC world.
