Summary

This paper proposes extensions to the OpenMP standard to provide first-class support for parallelizing generic libraries such as the C++

Standard Library (SL). Generic libraries are especially known for their ef- ficiency, reusability and composibility. As such, with the advent of ubiqui- tous parallelism, generic libraries offer an excellent avenue for parallelizing

the existing applications that use these libraries without requiring the ap- plications to be rewritten. OpenMP, which would be ideal for executing such parallelizations, does not support many of the modern C++ idioms such as iterators and function objects that are used extensively in generic libraries. Accordingly, we propose extensions to OpenMP to better sup- port modern C++ idioms to aid in the parallelization of generic libraries and applications built with those libraries.
