This file contains some useful aliases and way to handle multiple CUDA versions in Arch-based distributions. After doing all steps from CUDA installation, reboot system. Initially, CUDA will not be set up. You need to set it using alias set-cuda-X-Y. If you want to change version, you must first use unset-cuda alias, and then set new version.
# some useful aliases, not related to CUDA
alias ll='ls -alF'
alias la='ls -A'
alias l='ls -CF'
# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

# All things that you want to add to the path on login add before this comment!

- Download CUDA & CUDNN from https://archive.archlinux.org/packages/c.
- Install CUDA & CUDNN:
pacman -U cuda-X-Y. - Rename
/opt/cudato/opt/cuda-X.Y. - Uninstall CUDA & CUDNN:
pacman -R cudnn cuda(first remove cudnn).
- Remove file
/etc/profile.d/cuda.sh. - Rename
/etc/ld.so.conf.d/cuda.confto/etc/ld.so.conf.d/cuda-X.Y.conf, and change content of file to point to correct location. (same for CUDNN).
Repeat steps 1-4 to install all versions you need. At the end, if you want to have the latest version that will recieve regular updates, you can install it with pacman -S cuda cudnn. pacman will update only that version.
Then, you shoud do steps 5 and 6.
After system reboot, you should be able to activate X.Y version, simply typing in terminal set-cuda-X-Y.
