MW and Nvidia

I'm new to the Cuda world and need some help. I have 2 GTX 570s running like gang busters on PG and I've used them on GPUGrid.

Last night I thought I would see what kind of numbers they could put up on MW so I attached and got about 30 wu. Every wu immediately had a "computational" error. I wasn't able to get a single wu to crunch so I shut down MW Cuda.

Is there something special I need to do/know to get the Cudas to crunch MW? Has anyone actually done any Nvidia crunching since they changed to the new app?

Runniing the next to latest driver ... 266.58.

Their app is written in OpenCL - do you have the open_CL version of their driver installed?

Yes that driver supports 1.1, 3.1, and 4.1 versions of OpenCL.

Not sure if this helps... http://forums.nvidia.com/index.php?showtopic=197340

That may be the solution. I didn't realize you had to install an SDK to run the card on OpenCL. I assumed that was built into the driver. I will give it a try.

Thanks
