A display panel and a display apparatus having the display panel are disclosed. Software functions execute in response to output of the process engine. The agent module, upon receiving the messages, spawns processes to run the job, returning status notifications of the running job to the event processor. A method for operating a workcell may include the steps of: mapping ones of a plurality of testers to the plurality of movable part fixtures; maintaining the position of each movable part fixture; determining a current location of an active part fixture relative to a mapped tester; and minimizing the distance between the mapped tester and the active part fixture. In addition, the ATM processor and the host channel adapter may be configured for mapping the ATM cells and the InfiniBand packets on prescribed virtual circuits and prescribed InfiniBand\u2122 connections, respectively.
