Abstract
Abstract An equipment test program, stored and processed in a computer system, defines device termination procedures used for terminating devices used in a plurality of sets for performing a plurality of tests. The termination procedure for each device is associated with an ensemble, or group data structure. Each ensemble contains a set of termination task data structures for implementing the device terminations. Each task represents a device that operates with other devices in a test program module. Each task is linked to zero or more predecessor tasks in the ensemble. This linking represents the need to turn off the predecessor tasks' devices first before turning off any task's device. Within each test module, and before any device in the group is instructed to operate, the ensemble optimization procedure is invoked to pass a pointer to the module's ensemble data structure. The ensemble optimization procedure is used to optimally decide which device termination procedures should be invoked. Specifically, the ensemble procedure is used to determine which devices in the current ensemble must be turned off because they are not in the new ensemble. Those devices are turned off by recursively turning off their predecessor devices, then turning off those devices. Next, the procedure is used to determine which devices in the current ensemble must be turned off to allow installation of devices in the new ensemble. Again, those devices are turned off by recursively turning off their predecessor devices, then turning off those devices.
