This section gives short description of the hardware configuration of the general ESO computer facilities in Garching used for image processing. The main installation contains a number of UNIX workstations and Servers (most of which are SUN/SPARC compatible). The logical names of the workstations are ws n where n is a running number. The Servers have the prefix ns or mc depending on their main function as either file servers or main computers. In addition several X-terminal are available. All the systems are interconnected through a Local Area Network using TCP/IP protocols.
