Collecting Trace Files

While executing, your application collects trace files only if there is an appropriate collector library at the locations specified by the
INTEL_LIBITTNOTIFY32
or
INTEL_LIBITTNOTIFY64
environment variables. The
INTEL_LIBITTNOTIFY32
path is searched by 32-bit executables and the
INTEL_LIBITTNOTIFY64
path is searched by 64-bit executables.
To collect and convert trace files to use them with the Flow Graph Analyzer, chose one of the following options:
  • Collect traces by starting your application from the Flow Graph Analyzer GUI.
  • Set up your environment so a trace is collected when the application is started outside of the GUI.
Both approaches require you to build the application following the steps from Building an Application section for your operating system.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
