Hierarchically structured computer systems for analytical chemistry

For the Max-Planck-Institutes in Mülheim (Germany) a new centralized computer system has been designed and brought into operation in 1981. The system is built from two VAX 11/780 computers sharing peripheral resources. Experimental data from remote analytical instruments are gathered in real-time via satellite processors connected with coaxial cables and DMA-interfaces to the central computers. Several other small computer systems are transferring completed data files via asynchroneous serial lines.This centralized system is used for all kind of computer applications of the two institutes: for quantum chemical calculations, X-ray structure determinations, spectrometry and chromatography as well as for chemical literature search, text processing, administrative tasks, etc. The essential criteria for designing and using this or similar structured systems are discussed.
