2.3.1 Configuring Process Backend

The process backend is the default backend in YML. It is also the most simple to use. It does not need any middleware installed. It makes use of the parallelism provided by the operating system to simulate the execution of the application on a single host. In order to activate this backend you must edit the yml.xcf file and update the Backend group. This group defines the name of the backend plugin to load at runtime as well as the name of the configuration file. In order to use the Process backend you have to set the entry named module of the Backend group to ProcessBackend and set the entry init to the configuration file use for the Process backend. This file is generally named process.xcf. This file list the configuration elements related to the process backend. Those information will in most cases remains the same as the one generated during the installation process.
