Compiler Methodology for Intel® MIC Architecture
Vectorization Essentials, Vectorization and Optimization Reports
This chapter describes how to run and interpret Intel® C/C++ and Fortran compilers vectorization and optimization reports. These reports can pinpoint areas where the compiler is not adding vectorization or able to introduce optimizations. It may be possible to modify your code or communicate additional information to the compiler to vectorization or optimizations to be applied to the generated code for your application.
You should now know how to run vectorization and optimization reports to determine areas where vectorization could be enabled or optimization improved by the compiler with changes to your source code.
It is essential that you read this guide from start to finish using the built-in hyperlinks to guide you along a path to a successful port and tuning of your application(s) on Intel® Xeon Phi™ architecture. The paths provided in this guide reflect the steps necessary to get best possible application performance.
