OpenMP® ARB Releases OpenMP 5.2 With Improvements and Refinements

The OpenMP® Architecture Review Board (ARB) has released Version 5.2 of the OpenMP API. With this release of the standard, the OpenMP API improves its quality and usability. Join the OpenMP ARB at SC21 virtually or in-person at booth #919 to learn more about the specifics of Version 5.2.

"Version 5.2 refactors the OpenMP specification to improve consistency of its syntax and semantic restrictions," OpenMP Language Committee Chair Bronis R. de Supinski said. "The inclusion of C++ attribute syntax in OpenMP 5.1 motivated us to develop the 5.2 version, which is an addition to our usual release schedule."

New Features

Version 5.2 of the OpenMP specification was jointly developed by the OpenMP ARB, a group of major computer hardware and software vendors, as well as users throughout the OpenMP community. The updated specification includes the following key additions:

"Version 5.2 improves and simplifies the usage of the OpenMP API by the user," noted Michael Klemm, OpenMP ARB CEO. "In addition, the changes will also facilitate the automated generation of a variety of OpenMP documents, including our Quick Reference Guides, and so will improve the quality of the official OpenMP documentation."

Collection of programming examples

A collection of programming examples has been released by the OpenMP ARB in order to familiarize users with the directives, library routines and environment variables of the OpenMP API. The source code of the programming examples is available on GitHub.


Major vendors and open source compilers have implemented parts of the OpenMP 5 specification in their products. In addition, debugging and performance tools are being extended with OpenMP 5 features. More details on compilers and tools can be found on the OpenMP website.
