Vulkan Semaphores
For the vulkan interop samples there seems to be an issue with semaphore signals. If you simply comment out the signal from cuda side, it makes no difference and the program runs normally.
In theory it should halt the program because it's waiting on that signal during rendering. So it seems with Vulkan-Cuda interop the exported semaphores do nothing.
This is on Windows 10, latest driver for GTX 970 .
Edit: Timeline semaphores work ok, that's a good enough workaround for me.
