SMS 201,
a structured multiprocessor system (SMS) designed by Siemens during the late 70s, using an array of 128 8080 8-bit processors with 20 KiB of memory each to employ a MIMD technique of parallelism. The system, successor of the SMS 101 [1], is based on a 1976 patent by Siemens employees Rudolf Kober, Herbert Kopp, and Christian Kuznia [2] and comprises a control computer and an array of individual computers which cooperate under control of a process which establishes a three phase operation. In a control phase only the control computer operates, executes its program and informs the individual computers which function they must carry out during the next phase, called the autonomous phase. In this phase the individual computers simultaneously and independently fulfill their assigned functions and report completion thereof to the control computer. Finally, a communication phase is utilized for a data exchange between the computers.

SMS in Computer Chess

Christian Kuznia elaborated on the West German BMBF government-funded SMS concept at a workshop of the Gesellschaft für Mathematik und Datenverarbeitung (GMD) in Bonn, November 14, 1979, with Konrad Zuse et al. attending, and mentioned computer chess as one application of parallel computing [4].

Parwell

In cooperation of Siemens with the Technical University of Munich, a chess program for the SMS 201 was developed by three students, Thomas Nitsche, Elmar Henne and Wolfram Wolff - Parwell, which performed a distributed search and played the Second European Computer Chess Championship [5] [6] to qualify for Third World Computer Chess Championship, 1980, in Linz [7].
