 oneMKL Interfaces is an open-source implementation of the oneMKL Data Parallel C++ (DPC++) interface according to the [oneMKL specification](https://spec.oneapi.com/versions/latest/elements/oneMKL/source/index.html). It works with multiple devices (backends) using device-specific libraries underneath.
