Dear Freesurfer developers,
We have installed Freesurfer 5.0.0 (CentOS x86_64) on our compute cluster at Brown and are seeing the following error when running 'cudadetect':
ERROR: cuda driver does not appear to be installed! Detecting CUDA... There are 2 devices supporting CUDA: Device 0: "Tesla M2050" CUDA Driver Version: 3.20 (etc.)
However, the NVIDIA driver is installed and other CUDA programs function correctly:
[mhowison@gpu001 ~]$ nvidia-smi

Timestamp : Fri May 13 10:19:48 2011
Driver Version : 260.19.29
You can see our hardware specs here:

And output from bugr is:
---------------------------------------------------------------------
FREESURFER_HOME: /gpfs/runtime/opt/freesurfer/5.0.0
Build stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v5.0.0
RedHat release: CentOS release 5.4 (Final)
Kernel info: Linux 2.6.18-164.el5 x86_64
---------------------------------------------------------------------
We are using CentOS 5.4 and CUDA 3.2.16. Any ideas why Freesurfer cannot use our GPUs?
Thanks,
