OpenMP Library Reference

Provides links to constructs used in the OpenMP API.

The Visual C++ implementation of the OpenMP standard includes the following constructs.

Construct Description
Directives Provides links to directives used in the OpenMP API.
Clauses Provides links to clauses used in the OpenMP API.
Functions Provides links to functions used in the OpenMP API.
Environment Variables Provides links to environment variables used in the OpenMP API.

The Visual C++ OpenMP run-time library functions are contained in the following libraries.

OpenMP run-time library Characteristics
VCOMP.LIB Multithreaded, dynamic link (import library for VCOMP140.DLL).
VCOMPD.LIB Multithreaded, dynamic link (import library for VCOMP140D.DLL) (debug)

If _DEBUG is defined in a compilation and if #include <omp.h> is in source code, VCOMPD.LIB will be the default lib, otherwise, VCOMP.LIB will be used.

You can use /NODEFAULTLIB (ignore libraries) to remove the default lib and explicitly link with the lib of your choice.

The OpenMP DLLs are in the Visual C++ redistributable directory and need to be distributed with applications that use OpenMP.
