Hi, 
  thanks a lot for the suggestions. Yes I can run normal OpenCL C and
Java apps as well as CUDA  C/C++ applications. 
I installed my own R version ~/bin/R/ . I wonder If I need some
variables to specify OpenCL and CUDA appart from the LD_LIBRARY_PATH
(already set). It should be the Intel driver + CUDA driver (both). Here
it is only the Intel one. 
$ ./bin/R 
> library("gpuR")
> platformInfo()
$platformName
[1] "Intel(R) OpenCL"

$platformVendor
[1] "Intel(R) Corporation"

$platformVersion
[1] "OpenCL 1.2 LINUX"

$platformExtensions
 [1] "cl_khr_icd"                          
 [2] "cl_khr_global_int32_base_atomics"    
 [3] "cl_khr_global_int32_extended_atomics"
 [4] "cl_khr_local_int32_base_atomics"     
 [5] "cl_khr_local_int32_extended_atomics" 
 [6] "cl_khr_byte_addressable_store"       
 [7] "cl_khr_spir"                         
 [8] "cl_intel_exec_by_local_thread"       
 [9] "cl_khr_fp64"                         
[10] ""                                    

> gpuInfo()
Error: ViennaCL: FATAL ERROR: CL_DEVICE_NOT_FOUND 
 ViennaCL could not find a suitable device. Please check whether an
OpenCL implementation is properly installed and a suitable device
available.
Thanks
