Preserving time in large-scale communication traces
Prasun Ratn, Frank Mueller, Bronis R. de Supinski, Martin Schulz · 2008
Analyzing the performance of large-scale scientific applications is becoming increasingly difficult due to the sheer size of performance data gathered. Recent work on scalable communication tracing applies online interprocess compression to address this problem. Yet, analysis of communication traces requires knowledge about time progression that cannot trivially be encoded in a scalable manner during compression. We develop scalable time stamp encoding schemes for communication traces.
