Summary
The hybrid time-sharing system MACHYS is presented. It has been developed at the Hybrid Comp Centre of the Technical University in Vienna and is fully operational since September 1982. Up to 8 hybrid users can have simultaneous access to all hybrid computing resources, either from terminals or remote telephone links. The mathematical building blocks of a fully equipped EAI 680 analog computer are controlled by high level software commands in an machine independent way, using an electronic analog switch matrix and a self developed parallel logic processor. The interactive compiler HYBSYS supports a problemoriented, block structured model definition. Simple commands allow optimal online scaling, grafic and alphanumeric documentation as well as sophisticated experiments with the model like parameter optimization and nonlinaer zero finding.
An improved time-sharing algorithm, the results of some measurements and typical problem change times are presented.
