GPU-enabled images
We provide images with pre-installed Nvidia driver and CUDA package. These images contains the word "GRID" in their names and are regular ubuntu/centOS images with the following additions:
- There is a script which installs the correct version of the Nvidia GRID driver at boot. After a driver-update on the hypervisor this script will also update the driver in the VM.
- The CUDA-tools are pre-installed.
The installation of the drivers requires a restart; så the newly created instance will reboot shortly after creation.
Starting a GPU-instance
To start a GPU-enabled instance you simply create a VM as you usually would, but make sure to select:
- a GPU-enabled flavor
- a GRID-enabled image
After creating the VM it will boot, install the GRID-driver, and then reboot. So, do not be supprised if you suddenly loose access to your freshly booted machine. It will come back!
Warning |
---|
It is vital that the VM uses the same driver as the hypervisor. If you update this driver your vGPU will cease to function. When the driver is updated on the hypervisor a new driver will also be installed in your VM. |
Note |
---|
CUDA-versions are tightly coupled with the driver version. The CUDA-version bundled with the image is proved working. You can therfore not expect that a newer CUDA-version would work. |
cuDNN
Many of our GPU users will probably need Nvidia's cuDNN library. This is not pre-installed in our images, because Nvidia requires all users to register for the Nvidia Developer Program before dowloading. So, please follow the instructions here, to install it on your VM; and use tar file options. DO NOT USE THE DEB OR RPM ALTERNATIVE. Be sure to download the cuDNN version that corresponds to our current CUDA version.
Verify the GPU instance
After installation the presence of a GPU can be verified with lspci:
Code Block |
---|
ubuntu@gputest:~$ lspci | grep NVIDIA
00:05.0 VGA compatible controller: NVIDIA Corporation GV100GL [Tesla V100 PCIe 32GB] (rev a1) |
You can also verify that a license for the GPU is acquired successfully (yes, we need licences to use our GPUs...):

If the output results in a "PASS" you should be fine. The GPU is then ready to use.
Using Docker
Our GPU-enabled VMs altso supports NVIDIA Container Toolkit in order to use docker with GPUs. Rule of thumb is to follow the current installation guide from NVIDIA. Don't bother with the driver pre-requsities. We have already sorted those out for you in our image. You will of course need to install docker before you begin. That part is also described in NVIDIA's documentation. We've summed up the commands below. The examples is for Ubuntu only.
Install docker
