Setting up openCL

I will use openCL to do radio array computations faster.

I am running Scientific Linux on a Scientific Linux 6.2 system, Intel P4 3GHz 2CPU 12000 bogomips. My graphics card is an nVidia G92 9800GTX.

0) back up /etc/r
1) download the NVIDIA driver installer from http://www.nvidia.com/object/linux-display-ia32-310.44-driver.html
2) Turn off the nouveau driver.
- in /etc/grub.conf, add rdblacklist=nouveau to the end of each "kernel" line
3) reboot to single user, telinit 3
4) run the NVIDIA driver installer. Among other things, this will add /etc/modprobe.d/nvidia-installer-disable-nouveau.conf

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

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

download CUDA from https://developer.nvidia.com/cuda-downloads
Yikes! there is no entry for RHEL6 32 bit! Let's try RHEL5 32 bit.
- Click that button, download the 570MB cuda_5.0.35_linux_32_rhel5.x-1.run
- run that as root
modify the PATH to include /usr/local/cuda-5.0/bin . I put this in /etc/profiles.d/cuda.sh:
- PATH=/usr/local/cuda-5.0/bin:${PATH}
- export PATH
I put this in /etc/ld.so.conf.d/cuda.conf:
- /usr/local/cuda-5.0/lib
then ran ldconfig as root
samples:
- yum install freeglut
- ln -s /usr/lib/libglut.so.3 /usr/lib/libglut.so
- sh cuda*run -silent -driver -samples
- cd /usr/local/cuda-5.0/samples . . . . make
