Multiple smi

Look up GPU/CPU/RAM usage on multiple machines at the same time !

intended to work with python 3+

Based on pyNVML, and psutil.

Features

• Allows you to get nvidia-smi output and psutilinformation for multiple connected computers at once, and display it on a a selected GUI.
  • Availables frontends :
    • Ubuntu Appindicator
      • works best on Unity, partially supported on Gnome-shell
    • Argos
      • works on Gnome shell, but also on MacOS thanks to BitBar compatibility

• Allows you to get a notification every time a new process is launched or finished. A default minimum of 1GB memory use is needed for the notification to appear.
  • Available notification backends :
    • gnome libnotify
    • ntfy

• This tool is aimed at small research teams, with multiple GPU-equipped computers, which you can manually ssh to. At a glance you can see every usage of your computer stock, and where you can launch your computation. It also provides some basis if you want to develop a tool to automatically launch your computation on the least busy computer of your network.

Installation

Server side

[sudo] pip3 install multiple-smi[server]

You will then be able to install it as a service with the install_server_service command. See Usage/Server side below.

If you installed it with sudo, simply do

sudo install_server_service

If you installed it in a virtual environment, you will need to provide the path to the binary executable

sudo /path/to/venv/bin/install_server_service

For both cases, you can add the -h to get help.

Client side

You need to install these with your package manager (e.g. apt for ubuntu or brew for MacOS) :

• nmap
• libcairo2-dev
• libzmq3-dev
• python3-cairo-dev (ubuntu)
• py3cairo (mac)

sudo apt install nmap libcairo2-dev libzmq3-dev python3-cairo-dev

brew install nmap libcairo2-dev libzmq3-dev py3cairo

Gnome

If using appindicator frontend or gnome notifier, you will also need to install gnome related libraries with apt

Ubuntu 20+

sudo apt install libgirepository1.0-dev

Ubuntu 18

sudo apt install gir1.2-appindicator3-0.1

You will finally be able to install it with

[sudo] pip3 install multiple-smi[client]

Usage

Server side

To allow clients to access your computer's smi stats, simply run server_smi

But you can also enable it as a service that will be launched at boot.

Ubuntu 16+

A script is provided to automatically create the service file, whih will allow the server_smi to run automatically during boot (some options are available)

sudo install_server_service

to uninstall:

sudo install_server_service -u

(make the --systemd-path folder specified the same as during installation)

Ubuntu 14

You have to daemonize the script and put it in init.d, you can do it with the provided script server_smi_daemon.sh

sudo cp server_smi_daemon.sh /etc/init.d/.
sudo chmod 0755 /etc/init.d/server_smi_daemon.sh
sudo update-rc.d server_smi_daemon.sh defaults

to uninstall:

sudo update-rc.d -f service_smi_daemon.sh remove

Gpu usage stats:

Server-side, gpu usage history is stored in ~/.server_smi/{date}.csv if launched from CLI, /etc/server_smi/{date}.csv if launched from systemctl/init.d. Usage is written on it every ~60 sec, feel free to make some data science with it.

To enable it, you can use option -s in install_server_service or add it in server_smi_daemon.sh (line 6) before installing

Client side

to run the client_smi as only a CLI tool with no gui or notificaion:

client_smi

to run the appindicator

client_smi --frontend {argos,appindicator} --notify-backend {gnome,ntfy}

Configuration:

To know which servers have a running server_smi in your local network, you can use the discover_hosts script, it will automatically populate a json file in ~/.client_smi/hosts_to_smi.json with found machines.

The following command will try to connect to all ip addresses from 192.168.30.0 to 192.168.30.255 with the port 26110 and populate the hosts file.

discover_hosts --ip 192.168.30.0 --level 1 -p 26110

To add your own hosts manually, simply run a client_smi or discover_hosts once and add your entries in the json file that should be created here: ~/.client_smi/hosts_to_smi.json

Tunnel Connexion

Thanks to pyzmq backend for netork, a tunnel connexion is available, when you are outside your usual local network and have to go through a bastion.

Simply launch client_smi with --tunnel option set to your bastion address

client_smi --tunnel user@bastion_ip
