I’m trying to use Nsight to run a CUDA sample program on a Mac Pro which has two GPUs: Intel and Nvidia.
When I set a breakpoint in the kernel and run locally I get this message:
Local debugging on Mac is unsupported
My understanding is that cuda-gdb cannot be run on a GPU which is running X11. So how do I switch off X11 on the Nvidia GPU and only run it on the Intel one? I tried running muxProbe and switching to the “Integrated” GPU, but this had no effect.
I also read about a Beta feature which allows cuda-gdb to be run in concert with X11 on a GPU, so I tried this:
set cuda software_preemption on
But this didn’t help either.
I am running El Capitan and have a NVIDIA GeForce GT 750M .
