Abstract
A computer readable storage medium for executing a simulation process representing a collection of semiconductor devices and tests for the devices. The simulation process constitutes a batch job of a plurality of execution modules representing nodes of a directed acyclic graph. Each of the nodes contains a directory identifying any parent modules which have to be executed prior to executing the module, and identifying any child execution modules which are to be executed subsequent to executing the module. The directory also includes a status file indicating the state of execution of the module containing the directory. A supervisory processor performs a job farming operation on each of the execution modules in a distributed processing system. The execution modules are processed in an order defined by the identity of any parent and child modules referenced in the directories. At the completion of execution of a module, the status file of the directory is changed to indicate that the module has been executed.
