Abstract

In this paper, the Event Chain Clock synchronization algorithm is presented. This algorithm can maintain a global physical clock that reflects both the partial order and the elapsed time of all events occurred. This algorithm, which repeats some basic operations, has good astringency, and is suitable for parallel program performance debugging.
