As discussed in here : <a href="http://www.k-wave.org/forum/topic/multiple-gpus-k-wave-11">Multiple GPUs</a>, 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: </p> <p>| Selected GPU device id: 0 |<br /> | GPU device name: GeForce GTX TITAN X | </p> <p>What am I doing wrong?</p> <p>Thanks,<br /> Khan </p>
