Looking for a Double Precision capable NVIDIA GPU
The device GeForce GTX 460 from the command line cannot be used because a device supporting compute capability 1.3 (Double Precision) is required
Found 1 CUDA cards
Found a GeForce GTX 460
Device cannot be used, it does not have compute capability 1.3 support
No compute capability 1.3 cards have been found, exiting...

I thought that GTX460 supported DP

It does, but the CUDA app does not support FERMI cards at the moment.

Same here on my gtx 460--Cuda wu,s crashes because of a runtime failure.

Who knows. They're working on moving it all over to OpenCL to be able to support one piece of code for both ATI and Nvidia cards. But now the new Catalyst drivers crash and burn on WUs and the CUDA 2.3 app isn't working for a lot of cards, I'd say something needs to be fix and fixed fast.

I figured I would just poke this thread.

Is there any word yet on making the CUDA app support the fermi line of GPU's? I got a GTX 460 recently and of course it does not work here yet.

I doubt they will be rushing to do it - the Fermi line of cards had their Double Precision capability cut drastically as a design choice way back, to help compensate on the design nightmare NVidia had trying to get decent yields from production. Therefore even if the app ran for Fermis, the performance would be slow compared to single precision projects.

Apart from the fact that a GTX460 is more expensive, compaired to an HD4850 or even higher, although not the HD5700 series (SP) the 5800 are DP.

Difference in price is not that big, but they have already a working app for ATI cards, so little reason to invest a lot of time, money and several recourses, IMO!

[ADDED]
The GTX 460, 470 and 480, all have Compute Capabillity 2.0, don't know for sure if there are also Double Precision, though.
Will have a look :)
Anyone tried to reach the Lunatics WEB-Site? Look like it's down.

Single-precision Float: 637922 Mflop/s
Double-precision Float: 80093.9 Mflop/s


That illustrates the problem. The equivalent level card in the ATI lineup - ATI HD 5850 - figures are:

(Edit: Ooooppps .... a mere 100% out! Figures corrected, sorry about that ...)
Single Precision: 2.08 TeraFLOP
Double Precision: 416 GigaFLOP

Traditionaly Nvidia cripple the Double Precision to one eight single precision, and ATI cripple to one fifth single precision. Both do that to ensure cheaper consumer end cards do not blow away the much more hansomely priced Scientific Crunching cards (aka Tesla/Firestream). Tesla is half single precision speed (four times the rate for consumer cards).

Further up the ATI HD range you go, the more stark the DP performance difference. Software comes into it of course - but given a working ATI app, such a stark performance difference doesnt do a lot to motivate the effort for another codestream.

Precisely. The equivalent number two ATI card - 5870:

Single Precision: 2.7TeraFLOP
Double Precision: 540GigaFLOP

So is there an ETA for running Fermis yet? I have a 465 for gaming but would like to use it when im not at my machine for this purpose. So im not about to go get an ATI card or anything. I have a 260 working in my server but id like to up my numbers. Hopefully they will release support soon.

All compute-capability 1.3 and 2.0 cards have double precision.

If your prime motivation for the 465 is a numbers game, I suggest having a look at GPUGRID (their 260 hassles are over, and they have a good stable Fermi app). Even if the Fermi CUDA app here gets revamped and fielded, and I suspect that will be some time in coming, you will be hit by the reduced processing on Double Precision. GPUGRID is single precision, and therefore more suited to your 465.

Hmm i suppose in that case ill just leave my server to its thing and ill just turn my main pc off at night. I have all 4 cores of my server on the cause as well besides the GTX260. And my prime motivation isnt a numbers game like the people running WCG and F@H. I just wanted to add extra horse power under my name thats all. Seems double precision has been crippled severely on Fermi desktop variant =(
