[Starpu-devel] Data interfaces in StarPU

[Albert Sidelnik <sidelnik@gmail.com>]

I was hoping that somebody could explain how/where the routines that are part of the data interface system work. I am implementing my own interface that is based on the "variable interface" but instead of allocating new data or copying data, I only pass pointers around (somewhat similar to the cl_arg argument). Maybe I am missing something, but the allocate and copy routines never seem to be invoked. If what I am  trying to do is impossible or makes no sense, are there any better alternative options of using the data management system but without having to allocate data internally?

thanks
