Trying to use Torch7 CUDA

What is CUDA

CUDA® is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit.

Installing CUDA with torch7

how to install

lspci | grep 'VGA\|NVIDIA'
uname -m && cat /etc/*release
sudo rpm --install cuda-repo-rhel6-7.0-28.x86_64.rpm
sudo yum clean expire-cache
sudo yum install cuda

luarocks install cutorch

Oops, something goes wrong

I forgot to search for web whether my AMD graphic card can run CUDA

Lesson learned: do more research on graphic card before buying laptop.

It seems like the best alternative I can have is to use opencl with cltorch. However the cltorch is still under development, so means that I cant utilise my GPU power to run machine learning job with torch7. This is really unexpected for me.
