   Hi,

   I have two GTX TITAN X and I would like to use each in separate MATLAB sessions. As discussed in here : Multiple GPUs, I started two MATLAB sessions and called gpuDevice(1) in the first script and gpuDevice(2) in the other one. However, when the computation begins the output shows that the same GPU has been selected in both sessions:

   | Selected GPU device id: 0 |
   | GPU device name: GeForce GTX TITAN X |

   What am I doing wrong?

   Thanks,
   Khan

   Hi Khan,
   gpuDevice only works for the Matlab codes.

   If you use the CUDA code (kspaceFirstOrder3DG), then it is necessary to use a k-Wave parameter 'DeviceNum' and set the GPU Id here.
