Indeed, I overlooked this part in the manual. Copying/renaming the mentioned files did the trick.</p> <p>Thanks,</p> <p>Martijn </p> http://www.k-wave.org/forum/topic/example_tvsp_3d_simulation-on-gpu#post-3698 Wed, 05 Jun 2013 19:51:48 +0000 Bradley Treeby 3698@http://www.k-wave.org/forum/ <p>Hi Martijn,</p> <p>I just tried running the same example with the modifications you mention, but I'm unable to reproduce the error (it runs correctly). I tried on a system running 64-bit Windows 7, MATLAB 2012a, and CUDA 4.2 with a clean install of k-Wave 1.0 and GPUmat. </p> <p>Just to double check - did you copy (and rename) the files in the k-Wave Toolbox/other/GPUmat folder to the GPUmat/@GPUtype folder?</p> <p>Are you able to run any other examples (for example in 2D) or use the GPUmat toolbox independently of k-Wave?</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/example_tvsp_3d_simulation-on-gpu#post-3694 Tue, 04 Jun 2013 09:28:06 +0000 mdgreef 3694@http://www.k-wave.org/forum/ <p>Hi All,</p> <p>I just discovered the k-wave toolbox and I must say that I am really impressed by its capabilities.</p> <p>I am trying to modify the example 'example_tvsp_3D_simulation' so that it runs on the GPU. For this I am using GPUMat. The input parameters are adjusted as follows:</p> <p><code><br /> input_args = {'DisplayMask', source.p_mask, 'DataCast', 'GPUsingle',...<br /> 'CartInterp', 'nearest','DataRecast',true};<br /> </code></p> <p>and this is the only adjustment made.</p> <p>Running this example then gives</p> <p><em>Error using .*<br /> Number of array dimensions must match for binary array operation. (ERROR code 15)</p> <p>Error in GPUtype/bsxfun (line 19)<br /> y = feval(f,a,b);<br /> Error in kspaceFirstOrder3D (line 822)<br /> ux_sgx = bsxfun(@times, pml_x_sgx, ...</p> <p>Error in example_tvsp_3D_simulation (line 80)<br /> sensor_data = kspaceFirstOrder3D(kgrid, medium, source, sensor, input_args{:}); </p> <p></em></p> <p>Any help would be appreciated.</p> <p>Martijn </p>
