Theory and tool for estimating global time in parallel and distributed systems
Rutger F. H. Hofman, U. Hilgers · 2002
This article presents a method and a tool for estimating a global time base from local event traces. These event traces result from monitoring parallel and distributed systems of arbitrary topology, where the processors are working on a common application. The method relies on stability properties of physical clocks and on the causality relationships of cooperating processes. The tool copes with arbitrary communication structures, event trace formats, and any number of different clocks.
