Abstract

This paper presents a motivation and issues concerning the adaptation of PATOP, an OCM-based on-line performance analysis tool, to the MPI parallel programming library. It covers the general structure of an OCM-based monitoring environment, instrumentation of the MPI library and other enhancements needed both at low-level parts of the monitoring environment and at the user interface level in order to achieve full support of performance analysis of MPI applications.
