Abstract :
We introduce a tool that simplifies the performance assessment of input/output (I/O), memory, and Message Passing Interface (MPI) operations in a program under Linux. It describes how TAU improves the accuracy of measuring the extent of heap memory usage, and captures the volume and bandwidth of POSIX I/O performed in an un-instrumented program simply by modifying the command line for launching the parallel application. We describe the application of this tool to the Helios Rotorcraft Simulation Framework.
