## Note that this package will reboot half way. Hence the procedure after the reboot has to be carried out manually.


#1-Stage (before rebooting)
#=========================

	cd /share/apps/configrepo/
	wget http://anicca.usm.my/configrepo/howto/customise_centos/nvidia_cuda/inst_cuda_10.1.243_418.87.00_linux.run.txt
	chmod +x inst_cuda_10.1.243_418.87.00_linux.run.txt

	wget http://anicca.usm.my/configrepo/howto/customise_centos/nvidia_cuda/inst_cuda_9.2.148_396.37_linux.run
	chmod +x inst_cuda_9.2.148_396.37_linux.run



#Check that the nvidia gpu is seen by the system

	update-pciids
	lspci | grep -i nvidia

## Check if see if nouveau is on. 

	lsmod | grep nouveau

## if something is printed that means nouveau is on. We need to disable it.
# Disable Nouveau by creating a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
	
	rm -rf /etc/modprobe.d/blacklist-nouveau.conf
	echo blacklist nouveau > /etc/modprobe.d/blacklist-nouveau.conf
	echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nouveau.conf

#  Regenerate the kernel initramfs:

	sudo dracut --force
	reboot now



#2-Stage (after rebooting) - to be done manually after reboot
#============================================================
## After rebooting, log in as root.
 
	init 3


#Install cuda_10.1.243_418.87.00_linux.run (CUDA driver for CentOS 7, version 10.1) in /usr/local of a node. 
#Manual installation

	/share/apps/configrepo/inst_cuda_10.1.243_418.87.00_linux.run.txt


#Install cuda_9.2.148_396.37_linux.run (CUDA driver for CentOS 7, version 9.2) immediately after the installation of CUDA 10.1 while the terminal is still init 3.
#Install only the CUDA driver but not the video driver by following the instruction from 

	/share/apps/configrepo/inst_cuda_9.2.148_396.37_linux.run


# Set the CUDA default to CUDA-10 instead of CUDA-9.2
