ABSTRACT:
The method of the present invention provides a procedure for testing shared-memory 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 contending for at least one shared memory access address enters a "1" at the respective matrix element. For subcall pairs not sharing any memory address a ".O slashed." is entered.
