Is your feature request related to a problem? Please describe.

Today, C dispatch layer of parallel algorithms duplicates the logic in C++ dispatch layer. This is suboptimal, because we have to have extensive testing on both C and C++ ends to validate the logic, fix bugs and remember to introduce changes in multiple places.

Describe the solution you'd like

Research is needed to find ways to unify C++ and C dispatch layers.
