Adding Nvidia Tesla GPUs

in Technical Help (nuts n bolts)

Have a tesla GPU installed thats supposed to be able to handle several GB of data a second for stuff just like Daz but not sure how to get DAZ to see it and make use of it. Any help would be appreciated. 

Thanks

    Well, first off, I'm certainly not an expert by any means when it comes to the Tesla cards, but I do know a little bit. For example, I know that they use Nvidia GPUs, but they are not video cards perse, unlike the consumer and prosumer GeForce and Quadro cards, respectively. In fact many Tesla cards lack video outputs altogether. Instead, the Tesla cards are designed specifically for GPGPU computing in an HPC environment. The similarities between the GeForce and Quadro cards and the Teslas is merely that they use similar GPUs, and have CUDA cores. But they are not designed to be interchangeable. It is hypothetically possible to use consumer cards in an HPC environment (although it voids the warranty) but that is not what they are designed for. It may be possible to use a Tesla card in a non-HPC computer, assuming that the user has the ability to implement the CUDA technology for their purposes, but that is not what the Tesla cards are intended for. Perhaps you know all of this already.

    The problem as I understand it is that it is not DAZ Studio perse that is not recognizing the card, but rather that the CUDA implementation that DAZ Studio uses for the Iray render engine is not programmed to utilize Tesla cards, but is specifically implemented for the consumer cards. The only way that the Tesla card could be used would be if the CUDA programming for Iray was altered to accommodate it, which isn't likely. I know that relatively cheap used Tesla cards tend to pop up occasionally on auction sites and the likes, and it is easy for an uniformed individual to be enticed by the prospect of high CUDA core counts and onboard memory, only to discover that they haven't bought something that is a simple plug-and-play solution as they believed. Hopefully that isn't the case here.

    Long story short, I highly doubt that you are going to get that card to do what you want, and I also doubt anyone here can offer much hope of doing so. Maybe I'm wrong.

    What generation is the Tesla? The ones shopwing up on eBay at very low prices are very old and may no longer be supported by iRay (for instance the Fermi cards are not supported any more).

    You need to get the tesla driver.

    Is the card showing up to Windows? 

    Are you sure that DS doesn't see the card at all?

    Windows is seeing the card and the correct driver is installed. Its a K10 card. And DS only displays my GT240 as available for use.

    No, DS doesn't. The GT 240 doesn't have CUDA at all and is no longer supported by Nvidia much less iRay.
