CUDA on DualGPU Card (Like 9800gx2)

Accelerated Computing CUDA CUDA Programming and Performance
#1

I am just starting to educate myself about CUDA and was wondering if its possible to utilize both GPUs on my 9800gx2. I would like to run SETI@home on both GPUs if possible. As far as I know CUDA does not support SLI, but I can turn off SLI in the NVIDIA control panel on my 9800gx2.

Any thoughts or suggestions on how to get started on this?

Thanks!

When SLI is off, both CUDA devices will be visible to CUDA-enabled programs. If SETI@Home is designed to use multiple GPUs, then it should “just work.” (Some random browsing on Google suggests this is the case for SETI@Home.)
