Before You Begin

This section contains steps you should perform before you begin running analyses on your application with
Intel® Advisor
 or
Intel® Advisor Beta
.
  • Build an optimized binary of your application in
    release
     mode using settings designed to produce the most accurate and complete analysis results.
  • Verify the resulting executable runs before trying to analyze it with the
    Intel Advisor
    .

Product and Performance Information

1

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.
