Information on the NC A100 v4-series: Microsoft
Pre-requisites
Deploy a virtual machine on Microsoft Azure Portal.
Key values
- Size: NC24ads A100 v4 (also available NC48ads A100 v4 and NC96ads A100 v4)
- Image: Ubuntu HPC 20.04
- Availability: no redundancy required for benchmarking
Step 1: NVIDIA driver and CUDA
cd /mnt
nvidia-smi
If the driver version is less than 525, update both the driver and the CUDA versions
sudo wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
sudo wget https://developer.download.nvidia.com/compute/cuda/12.0.0/local_installers/cuda-repo-ubuntu2004-12-0...
sudo dpkg -i cuda-repo-ubuntu2004-12-0-local_12.0.0-525.60.13-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2004-12-0-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cuda
Restart the machine
sudo reboot
Step 2: Docker
The next step is to update Docker to the latest version.
cd /mnt
sudo apt update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update
sudo apt-get install docker-ce
Step 3: Mount the NVMe disks
cd /mnt
sudo vi nvme.sh
Copy and paste the following mounting script:
#!/bin/bash
NVME_DISKS_NAME=`ls /dev/nvme*n1`
NVME_DISKS=`ls -latr /dev/nvme*n1 | wc -l`
echo "Number of NVMe Disks: $NVME_DISKS"
if [ "$NVME_DISKS" == "0" ]
then
exit 0
else
mkdir -p /mnt/resource_nvme
# Needed incase something did not unmount as expected. This will delete any data that may be left behind
mdadm --stop /dev/md*
mdadm --create /dev/md128 -f --run --level 0 --raid-devices $NVME_DISKS $NVME_DISKS_NAME
mkfs.xfs -f /dev/md128
mount /dev/md128 /mnt/resource_nvme
fi
chmod 1777 /mnt/resource_nvme
Run the script to mount the disk
sudo sh nvme.sh
Step 4: Finish setting up docker
Update the Docker root directory in the docker daemon configuration file
sudo vi /etc/docker/daemon.json
Paste the following lines:
{
"data-root":"/mnt/resource_nvme/data",
"runtimes":{
"nvidia":{
"path":"nvidia-container-runtime",
"runtimeArgs":[]
}
}
}
Verify the previous steps and enable docker
docker --version
sudo systemctl restart docker
sudo systemctl enable docker
Register your user for Docker
sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker
You should not have any permission issues when running
docker info
