Installing OpenCL on compute nodes of Rocks

Hello.

Can some one possibly guide me on the installation of AMD's OpenCL SDK when Xwindows has to be specially installed. My usage case is for a cluster where some of the compute nodes have an AMD GPU.

[pmistry@compute-0-9 x86_64]$ ./CLInfo
terminate called after throwing an instance of 'cl::Error'
  what():  clGetPlatformIDs

Aborted
[pmistry@compute-0-9 x86_64]$ ./HelloCL
HelloCL!
Getting Platform Information
Platform::get() failed (-1001)

I tried installing X and Gnome on the compute nodes of the cluster using the yum groupinstall "X Window " "GNOME"

I have also switched to init 5.

When I run the CAL stuff I get the below problems.

[pmistry@compute-0-9 x86_64]$ ./FindNumDevices
Supported CAL Runtime Version: 1.3.185
Found CAL Runtime Version: 1.4.553
Use -? for help
CAL initialized.
Finding out number of devices :-
Device Count = 0
CAL shutdown successful.

Press enter to exit...

[pmistry@compute-0-9 x86_64]$ ./hellocal      
Supported CAL Runtime Version: 1.3.185
Found CAL Runtime Version: 1.4.553

I have followed the steps in. However in here it mentions to change the permissions of a non-existing directory in the .conf

I have setup the ICD and also have the env variables mentioned setup. If anyone can give me some pointers, I would greatly appreciate it.

This is similar to the thread but there has been no progress on that one.
