    OpenCL  cluster install for AMD Gpus

      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
      Use -? for help
      Segmentation fault

      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.
