Zusammenfassung:The method of the present invention provides a procedure for testing shared-memo ry multi-processor (SMMP) performance by formulating and modifying a given memory contention matrix (MCM), which is generated by collecting traces of memory addresses accessed by so-called subcalls in an SMMPCC. A subcall pair contendin g for at least one shared memory access address enters a "1" at the respective mat rix element. For subcall pairs not sharing any memory address a "~" is entered.
