I try to run the simpleMultiGPU sample from CUDA SDK 2.0. And the test is failed
Can someone explain me what happen, and what should i do to run that program on tesla ( I run it on the machine with 2 GTX9800 and it work fine)

Did you start X (with the nvidia driver)?

run the script to generate device nodes that’s in the 2.1 release notes (even if you’re running 2.0–it’s missing from the 2.0 release notes)

4

Could you make it clear, where is the script. I look at the CUDA_SDK_release_notes.txt and (2.1 version) could not see it mentioned any where

5

the 2.1 toolkit release notes, sorry.

It solved the problem. Many thanks
