Simplifying Memory, I/O, and Communication Performance Assessment Using TAU
Sameer Shende, Allen D. Malony, Alan K. Morris, Andrew M. Wissink · 2010
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.
