Enables the Auto-Parallelizer feature of the compiler to automatically parallelize loops in your code.
When the compiler automatically parallelizes loops in code, it spreads computation across multiple processor cores. A loop is parallelized only if the compiler determines that it is legal to do so and that parallelization would improve performance.
#pragma loop() directives are available to help the optimizer parallelize specific loops. For more information, see loop.
For information about how to enable output messages for the auto-parallelizer, see /Qpar-report (Auto-Parallelizer Reporting Level).
To set the /Qpar compiler option in Visual Studio
In Solution Explorer, open the shortcut menu for the project and then choose Properties.
In the Property Pages dialog box, under C/C++, select Command Line.
In the Additional Options box, enter
