Network GPU Info

Display GPU utilization for all hosts in your network.

Example

Prerequisites

First setup SSH keys to all computers that you want GPU info about. This is a good idea in general.

1. Once, from source computer:

    ssh-keygen -b 8192 -t rsa
   

   Use an empty passphrase.

2. For every remote computer, from your source computer:

    ssh-copy-id  yourusername@123.456.789.012
   

Usage

./network-gpu-info [options] [[user@]remote1 [[user@]remote2 [...]]]
./network-gpu-info [options] hosts.txt

If your username is the same between your source and your target computers, you don't need to prepend this to your remote host's address. This info is passed directly to the ssh command, so if it's valid when you use ssh, it will be valid here.

The command-line argument can alternatively be a regular text file, consisting of one entry per line. For example, a hosts.txt file could look like:

123.456.789.012
# user@remote1
remote2
localhost
another@10.0.0.5

A line can be commented-out by prepending it with #. You can specify the current, local machine using the entry localhost.

You can loop continuously using the --loop command-line argument. The default is to refresh every 5 seconds. You can change this by adding an integer: --loop 10 .

There is a --timeout option to change the default connection timeout (2 seconds).

Hostname Autocompletion

You can enable hostname autocompletion for this script, so that it suggests hostnames to connect to. Just add something like the following to your ~/.bashrc :

complete -F _ssh -f -o plusdirs ./network-gpu-info

Don't forget to reload it: source ~/.bashrc .

Todo

• Concurrent queries: currently implemented in the par branch
• Sorting output by utilization
• OpenCL support
