inline void op(

const instance_t &in,

instance_t &inout,

const exec_place &e,

) override

Reconstruct an instance by applying the reduction operator over it and another instance.

inline void init_op(

instance_t &out,

const exec_place &e,

cudaStream_t s,

) override

Initialize an instance with an appropriate default value for the reduction operator.
