Detailed Description

template<typename backend_tag>
struct heffte::backend::device_instance< backend_tag >

Holds the auxiliary variables needed by each backend.

The idea is similar to CRTP heffte::fft3d and heffte::fft3d_r2c inherit from this class and specializations based on the backend-tag can define a different set of internal variables. Specifically, this is used to store the sycl::queue used by the DPC++ backend.
