qopenmp-threadprivate, Qopenmp-threadprivate

Lets you specify an OpenMP* threadprivate implementation. This content is specific to C++; it does not apply to DPC++.

Syntax

Linux:

-qopenmp-threadprivate=type

Windows:

/Qopenmp-threadprivate:type

Arguments

type

Specifies the type of threadprivate implementation. Possible values are:

legacy	Tells the compiler to use the legacy OpenMP* threadprivate implementation used in the previous releases of the Intel® compiler. This setting does not provide compatibility with the implementation used by other compilers.
compat	Tells the compiler to use the compatibility OpenMP* threadprivate implementation based on applying the __declspec(thread) attribute to each threadprivate variable. The limitations of the attribute on a given platform also apply to the threadprivate implementation. This setting provides compatibility with the implementation provided by the Microsoft* and GNU* compilers.

Default

-qopenmp-threadprivate=compat
or /Qopenmp-threadprivate:compat

The compiler uses the compatibility OpenMP* threadprivate implementation.

Description

This option lets you specify an OpenMP* threadprivate implementation.

The threadprivate implementation of the legacy OpenMP run-time library may not be compatible with object files created using OpenMP run-time libraries supported in other compilers.

To use this option, you must also specify one of the following compiler options:

Linux* systems: -qopenmp or -qopenmp-stubs
Windows* systems: /Qopenmp or /Qopenmp-stubs

The value specified for this option is independent of the value used for the [q or Q]openmp-lib option.
