Is this ok [y/N]:

Once done, do a reboot,

# reboot

If after a reboot and if you do a “nvidia-smi” and receive an error like the one

# nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

You may want to take a look at https://gist.github.com/espoirMur/65cec3d67e0a96e270860c9c276ab9fa. It could be coming Secure Boot Option in your BIOS.

Webinar – Cloud-Native Supercomputing Powers New Data Centre Architecture

Computing power becomes the service. Data center becomes the new computing unit to serve the unlimited computing resource with high performance, flexibility and security. Network as the bridge between the computing resource and storage resource, between data centers and between the user and data center,  is becoming the key to impact performance and security. The Cloud Native Supercomputing architecture is designed to leverage the advantage from both supercomputer and cloud to provide the best performance in the modern zero trust environment.

By attending this webinar, you will learn how to:

  • Use the supercomputing technologies in data center
  • Deliver the cloud flexibility with supercomputing technologies to drive the most powerful data center
  • Provide the cloud native supercomputing service in zero trust environment

Date: February 23, 2022
Time: 15:00 – 16:00 SGT
Duration: 1 hour

nvidia-smi – failed to initialize nvml: insufficient permissions

The Error Encountered

If you are a non-root user and you issue a command, you might see the error 

% nvidia-smi
NVML: Insufficient Permissions" error

The default module option NVreg_DeviceFileMode=0660 set via /etc/modprobe.d/nvidia-default.conf. This causes the nvidia device nodes to have 660 permission. 

vim /etc/modprobe.d/nvidia-default.conf
options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=1001 NVreg_DeviceFileMode=0660

The Fix

[user1@node1 dev]$ ls -l nvidia*
crw-rw---- 1 root vglusers 195,   0 Jan  5 17:07 nvidia0
crw-rw---- 1 root vglusers 195, 255 Jan  5 17:07 nvidiactl
crw-rw---- 1 root vglusers 195, 254 Jan  5 17:07 nvidia-modeset

The reason for the error is due to the vglusers or video group. The fix is simply putting the users in the /etc/group

# usermod -a -G vglusers user1

Logged off and Login again, you should be able to do nvidia-smi

Yum Install Libraries and Dependencies

# yum group install "Development Tools"
# yum install kernel-devel
# yum install epel-release
# yum install dkms

Disable Noveau Drivers

Disable nouveau driver by changing the configuration /etc/default/grub file. Add the nouveau.modeset=0 into line starting with GRUB_CMDLINE_LINUX. This will disable the noveau driver after the reboot.

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet nouveau.modeset=0"
GRUB_DISABLE_RECOVERY="true"

Modifying the Grub.cfg

For BIOS User,
