Intel® Trace Analyzer 2017:

Trace Map

Trace Map enables you to zoom into the relevant subsets of large trace file Charts. It represents a miniature view of the MPI function activity over time. By default, the MPI function activity is shown in red color.

Intel® Trace Analyzer

Flat Profile

By default, the Flat Profile summarizes all major groups of functions and presents statistics over the processes. The exact contents of these groups depend on the group definitions stored in the trace file or you can define them by yourself. In the file poisson_icomm.single.stf, these are only MPI and Application groups.

General Preferences

The General Preferences enable you to set up the basic Intel® Trace Analyzer behavior, such as the startup options, view style, confirmation before quitting the Intel Trace Analyzer and the number of the recently opened tracefiles.

otf2-to-stf Utility

Note

This is a preview feature. A preview feature may be changed or removed in a future production release.

Synopsis

otf2-to-stf <options> <OTF2 file> 
--help
--version

Description

Use this utility to convert an OTF2 trace file to the STF format to be able to view the trace file in Intel® Trace Analyzer. After conversion the resulting file appears in the same directory as the input file.

Tracing User Defined Events

To get more detailed information about your application, you can instrument and trace various user-defined events in your application, including non-MPI function calls. In practice, it is often useful to record entries and exits to/from functions or code regions within larger functions.

Use the following Intel® Trace Collector capabilities:

  • Automatic function instrumentation with the compiler
  • Manual source code instrumentation with Intel® Trace Collector API
