Abstract

Periscope is a distributed automatic online performance analysis system for large scale parallel systems. It consists of a set of analysis agents distributed on the parallel machine. This article presents the architecture of the node agent and its central part, the search strategy driving the online search for performance properties. The focus is on strategies used to analyze memory access-related performance properties in OpenMP programs.
