Abstract — This paper describes TraceVis, a tool for graphically exploring application behavior as it relates to its execution on a microprocessor. Because the human mind can process enormous amounts of visual data–readily identifying trends and patterns– such a tool facilitates performance analysis by allowing raw data to be inspected rather than summaries of pre-selected characteristics. To this end, TraceVis has been designed to enable interactive navigation of many kinds data useful for studying performance problems including: relating the execution to disassembly and high-level language code, annotating the program trace with events (e.g., branch mispredictions and cache misses), and tracing instruction dependencies. In addition, Trace-Vis provides mechanisms for searching in traces and annotating traces (to bookmark areas of interest or mark regions previously characterized) to allow an analyst to focus their attention on the desired behaviors and regions. Along with exhibiting TraceVis’s features, this paper demonstrates how these features can be used in conjunction to analyze the performance of a simulated microprocessor’s execution. TraceVis is available in source form for non-commercial use . I
