    OpenCL FFT implementation

      Hi all,

      I`m trying to understand the following article related to subject:




      namely FFT_64 kernel. Author says:


      "The above shown listing begins with a function map_id() that computes the relative memory offsets within each workgroup."


      But how exactly should this function look like? I guess it should map instances to avoid bank conflicts but have no idea how exactly should this function be implemented. Can someone help me with that?
