Interoperability with Intel® VTune™ Amplifier XE

To simplify interoperability between Intel® Trace Analyzer and Intel® VTune™ Amplifier XE, Intel Trace Analyzer can generate a command line for mpirun / mpiexec.hydra targeted at analyzing specific processes with VTune Amplifier. It takes your original command line and modifies it in a way that you can run VTune Amplifier with it.

Note

This feature requires Intel® MPI Library version 5.0.2 or higher installed on your system, and is currently unavailable on Windows* OS.

Intel Trace Analyzer can generate the command line for:

A process identified by Intel Trace Analyzer as the most CPU-bound one. The command line is generated automatically and displayed on the Summary Page. If the command line is not available, link to the VTune Amplifier documentation is displayed.
Manually selected processes. To generate the command line open the Command line for Intel® VTune™ Amplifier XE dialog from one of the following menus:

Advanced > Command line for Amplifier XE...
Advanced > Process Aggregation: context menu of the selected process or processes.
Event Timeline chart: context menu of the selected process bar or process label. If your application is multithreaded, the command line will contain only process number rather than thread number.
Function profile > Load Balance tab: context menu of the selected process.

For example, if your original command line is:

$ mpirun –trace –n 128 a.out

And you need to analyze processes 33 and 44, the generated command line will look as follows:

$ mpirun –gtool “amplxe-cl –collect hotspots -r result:33,44” –n 128 a.out

Use the generated command line to analyze the specified processes with VTune Amplifier.
