3. Konrad-Zuse-Zentrum für Informationstechnik Berlin founded in 1984 by the Senate of Berlin: “Gesetz über das Zentrum für Informationstechnik (ZInfG)” “Dual Concept” • SC: scientific computing • CS: computer science & computer services ~200 staff members inclusive students and regular guests fast algorithms fast computers

4. The Roots: Konrad Zuse 1938: Zuse Z1, first programmable mechanical computer destroyed in World War II 1941: Zuse Z3, first programmable electromagnetic computer 2000 relays, 1/3 Flop/s Konrad Zuse 1920 - 1995 • Z1 has many features of • a modern computer: • freely programmable • separate memory • control unit with micro sequencer • floating point arithmetic
