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.
