Hi Massimo, I don't see why should anyone actually need any interface between Hadoop and CUDA in case that you're using C++? Why don't you just make sure that all of your data nodes are able to run CUDA locally, then write some function that uses CUDA and then just call this function inside your mapper or reducer?
