			'''note: OpenCL doesn't work yet. Here is what I tried so far'''

			The OpenCL applications in the NVIDIA GPU Computing SDK require a GPU with CUDA Compute Architecture to run properly. In order to use OpenCL, you have to load the CUDA environment:

			module load cuda

			Install version 2.3 of the NVIDIA GPU Computing SDK by executing the followin command

			bash /clusterfs/cortex/software/opencl-2.3/src/gpucomputingsdk_2.3a_linux.run

			It seems that you need gcc 4.3 in order to compile SDK. Change the following three lines in ~/NVIDIA_GPU_Computing_SDK/OpenCL/common/common_opencl.mk from

			CXX := g++
			CC := gcc
			LINK := g++ -fPIC

			to

			CXX := g++43
			CC := gcc43
			LINK := g++43 -fPIC

			You can compile all the code examples by running (fails at the moment):

			export LIBRARY_PATH=$LIBRARY_PATH:~/NVIDIA_GPU_Computing_SDK/OpenCL/common/lib/Linux64
			export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/NVIDIA_GPU_Computing_SDK/OpenCL/common/lib/Linux64

			cd ~/NVIDIA_GPU_Computing_SDK/OpenCL
			make

			The compiled examples can be found in the directory

			~/NVIDIA_GPU_Computing_SDK/OpenCL/bin/linux/release
