Setting up openCL

I am still developing the procedure that follows. I don't have openCL working yet.


I will use openCL to do radio array computations faster.

I am running Scientific Linux on a Scientific Linux 6.2 system (2.6.32 kernel), Intel P4 3GHz 2CPU 12000 bogomips. My graphics card is an nVidia G92 9800GTX (112 CUDA cores, 512MB RAM, PCIEx16 gen1). This drives a 20 inch Viewsonic 1400x1050 display.

See https://developer.nvidia.com/opencl

Setting up the nVidia driver

This adds a whole bunch of files and modules, including /etc/OpenCL with an nVidia vendor file.

The installed driver is 310.44, NV-Control Version 1.28

Note - I did this before setting up the SDK. The SDK may also have the driver!
