Abstract
Abstract A software configuration management system that uses a network computing environment to build large software systems in parallel. A configuration manager assigns the compilation of buildable components of a software system to different processors in the network. Buildable components are assigned in order, according to dependencies between components, independent components taking precedence. Processors are chosen according to the amount of idle time during a sampled time segment. A display provides processor compilation status messages for each compilation discrete from status messages of other compilations. A continuously updated overall status report of the system being built is simultaneously displayed with, but segregated from, the compilation status messages.
