CUDA supporting SLI on Linux? CUDA support for SLI

Accelerated Computing CUDA CUDA Programming and Performance

Initially I had been told that CUDA did not support SLI.

However, the other day I was running my code on dual 8800M GTX laptop, it looks like it is using both GPU although I did not specify.

nvidia-config shows both core temperatures are increasing.

Any comment?

CUDA does not use SLI. However that doesn’t mean that whatever CUDA code you were running wasn’t capable of using both GPUs. Also at least one of your GPUs was used for the display device, and the other might have been the CUDA GPU.

Thanks for the responses.

I did more tests, looks like CUDA is only using one GPU. In SLI, it thinks that there is only one GPU. And, it is physically using only one of the GPU.
