PAT

Abstract

The performance analysis tool (PAT) provides a low-overhead method for performing several types of performance analysis. You can use PAT to analyze a C, C++, or Fortran 90 executable file simply by relinking the executable file with the PAT library. With PAT, you can perform the following types of analysis: * Estimate the amount of time spent in functions * Determine load balance across processing elements (PEs) * Generate and view trace files * Generate an execution-time profile of a program * Analyze applications that use the pthread library * Analyze message passing programs * Time individual calls to routines * Perform event traces * Display hardware performance counter information by using the EV5 performance counters to gather performance information and instruction counts * Instrument call sites by using the real-time clock * Insert traces of user and library routines at the executable level
