GBT telescope and instrumentation control system hardware architecture: computers, networks, interfaces, and timing

The Green Bank Telescope (GBT) is designed to be a flexible instrument, accommodating many different types of front ends, back ends, and observing styles. In order to support this flexibility, a system architecture was developed according to the principle of modularity. The system is a loosely coupled group of cooperating computers, tied together to form a complete system. The hardware design of the GBT Control System will be presented. The computer architecture, network architecture, and system synchronization and timing methods will be addressed. Progress towards implementation will be described, and the lessons learned as a result of implementing the system will be covered.
