An Implementation of the POMP Performance Monitoring Interface for OpenMP Based on Dynamic Probes

Abstract

Abstract. OpenMP has emerged as the standard for shared memory parallel programming. Unfortunately, it does not provide a standardized performance monitoring interface, such that users and tools builders could write portable libraries for performance measurement of OpenMP programs. In this paper we present an implementation of a performance monitoring interface for OpenMP, based on the POMP proposal, which is built on top of DPCL, an infrastructure for binary and dynamic instrumentation. We also present overhead measurements of our implementation and show examples of utilization with two versions of POMP compliant libraries.
