Updating to CUDA 6.5 on Fedora 20

Assuming you installed CUDA 6 following my previous guide, updating to 6.5 is pretty simple, first, remove the old (Fedora 19) repo:

# yum remove cuda-repo-fedora19

Now, update to the new Fedora 20 CUDA 6.5 repo:

# rpm -ivh http://developer.download.nvidia.com/compute/cuda/repos/fedora20/x86_64/cuda-repo-fedora20-6.5-14.x86_64.rpm

Update CUDA (still haven't fixed the EULA spam):

# yum update cuda cuda-cross

Finally, update the paths you export to the following:

export PATH=/usr/local/cuda-6.5/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib64:$LD_LIBRARY_PATH

Note for users of the RPM Fusion 'akmod-nvidia' package: The above will update your driver to the Nvidia version of 'akmod-nvidia' (340.29-2 at the time of this writing) unless you are running the newer version from the RPM Fusion testing repo. This was fine with me. I do not know if it is possible to successfully use CUDA 6.5 with an older driver.

Compiling CudaMiner on Fedora 20

Are you interested in getting into the scrypt based cryptocurrency mining game, but only have a lowly Nvidia card? Lucky for you, it is entirely possible to mine scrypt based coins (eg. Litecoin, Feathercoin) using an Nvidia GPU. CudaMiner makes it possible.

Setting up CUDA on Fedora 20

Installing Nvidia's CUDA on Fedora is pretty simple, but the official documentation (warning, PDF link) falls a little short if you are using the Nvidia drivers packaged by RPM Fusion. If you are using the officially packaged Nvidia drivers, just follow the official docs, otherwise follow along after the break.
