# OAR 2.6 documentation

## Desktop computing

If you want to compute jobs on nodes without SSH connections then this feature is for you.

On the nodes you have to run “oar-agent.pl”. This script polls the OAR server via a CGI HTTP script.

Usage examples:

  - if you want to run a program that you know is installed on nodes:

        oarsub -t desktop_computing /path/to/program

    Then /path/to/program is run and the files created in the oar-agent.pl running directory is retrieved where oarsub was launched.

  - if you want to copy a working environment and then launch the program:

        oarsub -t desktop_computing -s . ./script.sh

    The content of “.” is transfred to the node, “./script.sh” is run and everything will go back.
