Performance Visualization for the PVFS2 Environment

This document describes how to use the functionalities of SLOG21 trace file format in order to facilitate complex visualization concepts in parallel environments. How to analyze trace files generated by parallel I/O activities using MPE 2 for PVFS2 3 is the basis of this analysis. Implemented set of utilities help improve the user defined performance analysis and visualization of SLOG2 trace files. Chapter 1 takes an overview of the parallel file system, tracing libraries, logging formats, and visualization programs. Chapter 2 specifies the needs in visualizing the PVFS2 servers and clients together in order to do performance measurements. Chapter 4 describes the used design methods. Chapter 5 describes some of the implementation methods used to achieve the specified goals. An example illustration using the implemented tools is included in chapter 6. Chapter 7 describes the conclusions. Chapter 8 and 9 respectively describe the future works and possible future enhancements
