Parallelization Options Overview

For shared memory parallel programming, the Intel® C++ Compiler supports the OpenMP, version 1.0 API. The Parallelization capability of the Intel C++ Compiler uses the following options.

Option Description
-parallel Enables the auto-parallelizer to generate multi-threaded code for loops that can be safely executed in parallel. Default: OFF
-par_threshold{n} Sets a threshold for the auto-parallelization of loops based on the probability of profitable execution of the loop in parallel, n=0 to 100. Default: OFF
-par_report{0|1|2|3} Controls the auto-parallelizer's diagnostic levels.
Default: -par_report1.
-openmp Enables the parallelizer to generate multi-threaded code based on the OpenMP directives. Default: OFF
-openmp_report{0|1|2} Controls the OpenMP parallelizer's diagnostic levels. Default: -openmp_report1
