Detailed Description

A specific execution instance of a workunit assigned to a host.

Bridges the workunit definition and the actual execution on a grid node. Tracks PGMQ lease state, server-side lifecycle (Inactive/Unsent/InProgress/Done), and the location of output data. The BOINC equivalent of 'result'.
