Unable to run cuda on GPU as user


We are using NPACI rocks cluster 5.3 for a 3 node cluster and we have 8400 GeForce GS GPU’s on two compute nodes and one frontend without GPU. We installed the NVIDIA 256.35 drivers and we also installed cuda 3.0 on all the 3 nodes and we installed GPU SDK as user on all 3 nodes.

When we tried to run the sample device project as user we are getting the API error saying that there is no device that support cuda. When we install the GPU SDK as root and when we run the same device query it is showing the GPU and everything is working fine.

We edited the _bash_profile and .bashrc for both user and root.

Can anyone please help us how can we run device query as user and get the program running on gpu by cuda.

Please help me.
