Initial experiences with RP3 performance monitoring

To understand the system interdependencies of a multiprocessor and the effects of these interdependencies on parallel applications, it is necessary to include a performance monitoring facility in the multiprocessor system. Such a monitoring facility can be either transparent (i.e. requiring no user initiated intervention) or non-transparent. In this paper we describe the performance monitoring facilities that are available to the user of the RP3 system. We will also describe our initial experience using these facilities and demonstrate their functionality.
