Introduction

EUMETSAT infrastructure contains RX A6000 NVIDIA GPU cards. To employ the GPU, one need to provision one of the following flavors:

Flavor namevCPURAMvGPU TypevGPU RAMSSD storage (GB)
vm.a6000.1214 GBRTXA6000-6C6 GB40
vm.a6000.2428 GBRTXA6000-12C12 GB80
vm.a6000.4856 GBRTXA6000-24C24 GB160
vm.a6000.816112 GBRTXA6000-48C48 GB320

Provision

To use the GPUs:

  1. Provision new Centos or Ubuntu instance.
  2. Select layout ending with eumetsat-gpu and one of the plans listed above. Beside that, configure your instance as preferred and continue deployment process.
  3. Once VM is deployed, you can verify GPUs for example using nvidia-smi program from command line (see below for confirming library installations and drivers).

Usage

Essential commands

You can see GPU information using nvidia-smi 

# Login to your instance and run below command
$ nvidia-smi

# Check if the input you received shows the NVIDIA-SMI, Driver and CUDA versions. You can also see the GPU hardware (e.g., RTXA6000-6C) and the GPU memory

# NVIDIA tools are available in /usr/local/cuda-11.8/bin/. You can add them to PATH following:
$ export PATH=$PATH:/usr/local/cuda-11.8/bin/

Installing Libraries

You can install a variety of libraries using different methods. Below, we have a basic tutorial showing you how you can install libraries such as TensorFlow, Keras and PyTorch with conda package manger. CUDA version is currently 11.4 which need to be the same with drivers and thus can't be changed.  Tensorflow library compatibility is available at: https://www.tensorflow.org/install/source#gpu.

Using conda

# install miniforge (or any conda manager)
$ wget https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-Linux-x86_64.sh

# make it executable
$ chmod +x Miniforge3-Linux-x86_64.sh

# run and install the executable
$ ./Miniforge3-Linux-x86_64.sh


# create a conda environment called ML with Python 3.8
$ conda create -n ML python=3.8

# activate the environment
$ conda activate ML

# install packages, note that installing tensorflow-gpu and keras also installs many number of extra libraries such as CUDA toolkit, cuDNN (CUDA Deep Neural Network library), Numpy, Scipy, Pillow
(ML) $ conda install tensorflow-gpu keras

# (OPTIONAL) cudatoolkit is installed automatically while installing keras and tensorflow-gpu, but if you need a specific (or latest) version run below command.
(ML) $ conda install -c anaconda cudatoolkit

# (OPTIONAL) installing pytorch GPU, pytorch might need cuda 11.8
(ML) $ conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia

Installation Confirmations

Here we run a few initial commands for different libraries & drivers for confirming the library integrations with the GPU.

print(tf.__version__)

import torch
print(torch.__version__)

    2.2.0


print(torch.cuda.is_available())

    True


print(torch.version.cuda)

    11.8


if torch.cuda.is_available():
    # Create a tensor and move it to GPU
    x = torch.tensor([1.0, 2.0]).cuda()
    print(x)  # Print the tensor to verify it's on the GPU
else:
    print("CUDA is not available. Check your PyTorch installation.")

    tensor([1., 2.], device='cuda:0')

Using Docker

If you want to use GPUs in docker, you need to take few extra steps after creating the VM.


$ sudo apt install -y docker.io
$ sudo usermod -aG docker $USER


$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
$ sudo yum install docker-ce docker-ce-cli containerd.io
$ sudo systemctl --now enable docker
$ sudo usermod -aG docker $USER


To provide support for docker to use the GPU, you need to install the NVIDIA Container Toolkit.  You can follow instructions on NVIDIA's website or basically do:

$ distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
$ curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
$ curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
$ sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
$ sudo systemctl restart docker


$ distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
   && curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.repo | sudo tee /etc/yum.repos.d/nvidia-container-toolkit.repo
$ sudo yum clean expire-cache && sudo yum install -y nvidia-docker2
$ sudo systemctl restart docker

Test the install with:

$ docker run  --rm --gpus all nvidia/cuda:11.0.3-base-ubuntu20.04 nvidia-smi
