Cuda RTOS Support ?

Hi,

i’m about to create a programm that should response in a given time.
Now i’m evaluation a few possibilities. I’m pretty new to the RTOS-topic
so please turn a blind eye :)

My first question is, if its possible to run a Cuda application under QNX or any other RTOS?
Or is it possible to run Linux in “RTOS-Mode” and keep a Cuda programm running to response intime?

My concern is to use both advantages (Cuda for fast performance and RTOS to only keep running that specific programm)
and i dont know if that is possible anyway.

Any help would be appreciated!
Thanks for your time!
