 ### Code Reuse
-It is a priority to reuse as much as we can which already exists and has been reviewed within oneDPL. We want to
-minimize adding requirements for parallel backends to implement, and lift as much as possible to the algorithm
-implementation level. We should be able to avoid adding a `__parallel_histogram` call in the individual backends, and

 ### unseq Backend
 Currently oneDPL relies upon openMP SIMD to provide its vectorization, which is designed to provide vectorization across
