Installing CUDA

Procedure

1. Use PuTTY to log in to the server as the root user.
2. Check whether the Nouveau driver is disabled.

   lsmod |grep nouveau

   • If a command output is displayed, the Nouveau driver is not disabled. In this case, perform 3.
   • If no command output is displayed, the Nouveau driver is disabled. No further action is required.
3. Disable the Nouveau driver.
   1. Create a disable-nouveau.conf file.

4. Back up the initramfs file and create a new one.

   cp /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img 
   dracut -f /boot/initramfs-$(uname -r).img $(uname -r)

5. Restart the computer.

   reboot

6. Check whether the Nouveau driver is disabled (no command output is displayed).

   lsmod |grep nouveau

7. Install NVIDIA CUDA.

   wget https://developer.download.nvidia.com/compute/cuda/11.4.0/local_installers/cuda_11.4.0_470.42.01_linux_sbsa.run
   sudo sh cuda_11.4.0_470.42.01_linux_sbsa.run

8. Set the environment variables.

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

9. Verify the version.

   nvcc -V
