I am a CUDA trainer at Applied Parallel Computing (http://parallel-compute.com), NVIDIA partner. For a long time, we have been using NetBeans in our trainings. CUDA support in NetBeans is very basic, but remote development feature is essential for us. Usually attendees come with their laptops that might have neither NVIDIA GPU nor CUDA Toolkit installed; with NetBeans, students are able to upload the code via SSH, compile it remotely, run it and see results with one click.
Unfortunately, even with CUDA 5.0 we have to resort to NetBeans with its limited CUDA support, because Nsight Eclipse Edition lacks remote development. I know that this feature has been planned for future releases; any info on the roadmap and estimated time of availability?
