Structure of FBSNG

FBSNG is composed of a set of daemon processes that monitor, control, and run jobs on the farm nodes. This section is provided to give a brief description of the structure of FBSNG. It is not necessary to know anything about the FBSNG internals in order to use it. This section is purely informational.

• bmgr: The bmgr (batch manager) runs on the FBSNG control node. It is responsible for accepting new jobs, scheduling, queueing, dispatching, managing resources, and maintaining connections with the launcher (see below).
• launcher: The launcher is a daemon process that is responsible for starting and monitoring user processes. The launcher runs on every node in the cluster, communicating status information to the bmgr and API..
• logger: This daemon is used to log FBSNG status and error messages.
• User Interface (UI): A set of commands that allow users to submit, monitor, and control jobs.
• Graphical User Interface: A GUI implementation of the UI.
• API: The Application Programmers Interface.
