There are two proposed parts of this talk - 
Part 1 - Integration: 

Intel have offered to contribute an implementation of the C++17 parallel algorithms to libstdc++ (GCC) 
and libc++ (Clang). This talk will cover - 
* brief introduction to C++17 parallel algorithms and execution policies 
* overview of Intel's implementation 
* considerations and changes necessary to integrate a substantial 3rd party contribution like this 
into a standard library implementation. 
* support for different execution back ends, tailored to the target platform 

Part 2 - Mapping parallel algorithms to the proposed Executors design: 

There is strong support for Executors to be part of the next version of C++. Support for parallel algorithms targeting 
the proposed Executors design will be an important part of that work. The Intel parallel algorithms implementation 
currently being integrated into libstdc++ and libc++ provides basic support for pluggable execution environments. 
This talk would cover integrating the current Executors design as a concrete execution target for the parallel 
algorithms implementation, with a focus on how you would use the proposed Executors API as a target for common 
parallel algorithm implementations.
