The monitoring request interface (MRI)
Edmond Kereku, Michael Gerndt · 2006
In this paper we present MRI, a high level interface for selective monitoring of code regions and data structures in single and multiprocessor environments. MRI keeps trans-parent the available monitoring resources from the perfor-mance analysis tools and can electively generate monitor-ing results as online profile information, or as postmortem traces. MRI is the first step toward a standard monitoring interface which can be used by a broad range of perfor-mance analysis tools, from profiler tools, trace producers and visualizers, up to complex automatic performance ana-lyzers. We also present an implementation of MRI for SMPs which transparently use a simulation backend and a PAPI backend to obtain performance data.
