So to set your device to the zeroth Nvidia device, use:</p> <p><code>gpuDevice(1);</code> </p> http://www.k-wave.org/forum/topic/shear-wave-simulation-in-3d-by-gpu#post-7060 Fri, 27 Sep 2019 01:10:34 +0000 elliotP 7060@http://www.k-wave.org/forum/ <p>Hi Patrick,</p> <p>I am not familiar with the MATLAB parallel computing toolbox. How can I use the DataCast option setting 'gpuArray-single' to running pstElastic3D on the GPU? Can you recommend any document for me?</p> <p>Thank you,<br /> Michael </p> http://www.k-wave.org/forum/topic/shear-wave-simulation-in-3d-by-gpu#post-7055 Fri, 20 Sep 2019 08:21:09 +0000 saturnnan 7055@http://www.k-wave.org/forum/ <p>Hi,Patrick:<br /> Thanks a lot!<br /> That is really helpful to me.The time consumption of simulation reduced by 35%.<br /> The computational efficiency of this function does not seem to be as efficient as the kspaceFirstOrder3DG.<br /> Can not wait for the cuda version of pstElastic3D :)</p> <p>Thanks again!</p> <p>Hank </p> http://www.k-wave.org/forum/topic/shear-wave-simulation-in-3d-by-gpu#post-7054 Thu, 19 Sep 2019 18:44:14 +0000 Patrick 7054@http://www.k-wave.org/forum/ <p>Hi,</p> <p>You can use the DataCast option set to 'gpuArray-single' to run pstElastic3D on the GPU. This requires the MATLAB parallel computing toolbox.</p> <p>Hope this helps,</p> <p>PC </p> http://www.k-wave.org/forum/topic/shear-wave-simulation-in-3d-by-gpu#post-7052 Thu, 19 Sep 2019 03:41:03 +0000 saturnnan 7052@http://www.k-wave.org/forum/ <p>Hello, everyone:<br /> I am trying to simulate acoustic shear wave propagation using k-wave pstdElastic3D function.It took a long time for one simualtion.<br /> Is there any method or related function that makes this simulation work on the GPU?</p> <p>Thanks a lot!</p> <p>Hank </p>
