Performance-measurement tools in a multiprocessor environment

A family of monitoring facilities is proposed which are used in combination, e.g. a breakpoint monitor used for debugging purposes, a mailbox monitor for analysis of synchronization traffic, and a bus monitor for measurements of bus load. These tools are used in multi-monitor mode, for which both a common programming-language interface and a user interface are provided. Design concepts are presented, along with the overall structure of such an integrated monitoring tool set in a multiprocessor environment. How a combination of hardware and software monitors is embedded into a MODULA-2 multiprocessor environment is outlined, as a case study.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
