METHOD FOR TESTING AND MITIGATING SHARED MEMORY CONTENTION IN MULTI-PROCESSOR SYSTEMS

摘要

The method of the present invention provides a procedure for testing; shared-memorymufti-processor (SMMP) performance by formulating and modifying a given memorycontention matrix (MCM), which is generated by collecting traces of memoryaddresses accessed by so-called subcalls in an SMMPCC. A subcall paircontendingfor at least one shared memory access address enters a "1" at the respectivematrixelement. For subcall pairs not sharing any memory address a ".SLZERO." isentered.
