Hi, We are in the process of developing a non-tracking safety Radar and would really appreciate some guidance in selecting a real-time operating system especially with the aim of offloading processing to a GPU. Can anyone share their experience with real-time GPU offloading on either Xenomai or Realtime Linux (PREEMPT_RT patch)? I have read reports on 900us delays with Nvidia graphics drivers, has this been resolved?
Background: The application basically requires the radar to output a disable signal, within 100ms, when an object is detected. Radar data is received every 1 ms and processed. Platform: x86_64, most likely Intel i7 CPU Total processing latency: 100ms Interrupt frequency: 1KHz >From what I can read both Xenomai and Realtime Linux should easily meet these requirements, but what about RT GPU support? Thanks a lot, -- Rudolf Meijering
