optiworker

The optiworker application represents the workstation layer of the framework. It receives single tasks from the optimaster and executes them according to the task description. The optiworker can run in two modes, normal mode and token mode. In normal mode, the optiworker will launch dispatcher processes directly and under the same privileges as the optiworker process. In token mode, a token system will be used to securely identify users to which a certain task belongs. In this mode, the optirooter application will be used to launch the dispatcher process. See section 3.5 for more information.

You can specify some options for the optiworker using a configuration file in /etc/optiworker.conf. An example configuration file is present in /usr/share/optiworker/optiworker.conf.ex. The available configuration settings are listed in table 3.2.
