Can I safely use OpenMP with C++11?

Question

The OpenMP standard only considers C++ 98 (ISO/IEC 14882:1998). This means that there is no standard supporting usage of OpenMP under C++03 or even C++11. Thus, any program

Like Jim Cownie, I’m also an Intel employee. I agree with him that Intel Threading Building Blocks (Intel TBB) might be a good option since it has loop-level parallelism like OpenMP but also other parallel algorithms, concurrent containers, and lower-level features too. And TBB tries to keep up with the current C++ standard.

And to clarify for Walter, Intel TBB includes a parallel_reduce algorithm as well as high-level support for atomics and mutexes.

You can find the Intel® Threading Building Block’s User Guide at http://software.intel.com/sites/products/documentation/doclib/tbb_sa/help/tbb_userguide/title.htm The User Guide gives an overview of the features in the library.
