The complexities of monitoring and controlling the various DIII-D tokamak systems have always required the aid of high-speed computer resources. Because of recent improvements in computing technology, DIII-D has upgraded both hardware and software for the central DIII-D control system. This system is responsible for coordination of all main DIII-D subsystems during a plasma discharge. The replacement of antiquated older hardware has increased reliability and reduced costs both in the initial procurement and eventual maintenance of the system. As expected, upgrading the corresponding computer software has become the more time consuming and expensive part of this upgrade. During this redesign, the main issues focused on making the most of existing in-house codes, speed with which the new system could be brought on-line, the ability to add new features/enhancements, ease of integration with all DIII-D systems and future portability/upgrades. The resulting system has become a template by which other DIII-D systems can follow during similar upgrade paths; in particular DIII-D's main data acquisition system and neutral beam injection (NBI).
