simple abstraction layer on top of other vectorization libraries
It provides an architecture-independent API for expressing vector operations on data. Code written with this API can then be dispatched to one of several backends like Vc, or a scalar implementation. This allows one to get the best performance on platforms supported by Vc without losing portability to unsupported architectures like ARM and PowerPC, for example, where the scalar backend can be used instead without requiring changes in user code.
