That's reasonably straightforward to build yourself, but is missing one small piece (custom dtype registration, so that the code generator knows what C type to write when you give it a homegrown dtype) in PyCUDA. The idea would be to write your own reducer that operates on structs containing both item and position. You can either patch that into PyCUDA yourself, or wait for me to do it--I should have time to do that by early next week. Andreas
