The APE Computer and Lattice Gauge Theories
In this note I will say something about building a computer dedicated to Theoretical Physics. Ref.1 is a technical report about the Ape computer (Array Processor with Emulator), and the interested reader should refer to it for complete technical details. Here I will just try to give some feelings about the strategic decisions the Ape collaboration people did, and about the kind of physics people will be able to do with such a machine. I will mainly be concerned (both because of the nature of the Ape and of the nature of this meeting) with numerical simulations of Lattice Gauge Theories (LGT).
