Abstract
Performance analysis and optimization is an important part of the development cycle of HPC applications. Among other prerequisites, it relies on highly precise timers, that are commonly not sufficiently synchronized, especially on distributed systems. Therefore, this paper presents a novel timer synchronization scheme especially adapted to parallel event tracing. It consists of two parts. Firstly, recording synchronization information during run-time and, secondly, subsequent correction, i.e. transformation of asynchronous local time stamps to synchronous global time stamps.
