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

Answer 1

I'm actually interested in high-performance computing, but OpenMP (currently) does not serve my purpose well enough: it's not flexible enough (my algorithm is not loop based)

Maybe you are really looking for TBB? That provides support for loop and task based parallelism, as well as a variety of parallel data structures, in standard C++, and is both portable and open-source.

(Full disclaimer: I work for Intel who are heavily involved with TBB, though I don't actually work on TBB but on OpenMP :-); I am certainly not speaking for Intel!).
