Abstract: A logical structure for understanding and control of basic performance conaWemfzWs of distributed high-performance computing; systems in engineering is presented in Westphal ef of. [1] and Westphal [2]. This structure is expanded in this paper on a methodology for the supervisory control of such systems. The supervisory control can be realized using the performance considerations mentioned above and the generalized stochastic Petri mef (GSPN) model of the /z6re a'5M6%(e(f oWo Wer/ace (FDDI) presented in this paper.
