However, if you have access to the PCT, that will definitely be easier in the long run, and the performance is also quite a bit better (there are some comparison plots in Sec. 3.8 of the k-Wave manual).</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/gpuinfo-invalid-mex-file#post-4716 Thu, 11 Sep 2014 18:32:45 +0000 deanz1 4716@http://www.k-wave.org/forum/ <p>Thanks for the prompt reply. It happens even with GPUstart command</p> <p>I suspect that it's a problem with GPUmat not supporting modern CUDA cards so I'm moving over to buy parallel computing toolbox. </p> http://www.k-wave.org/forum/topic/gpuinfo-invalid-mex-file#post-4715 Thu, 11 Sep 2014 14:40:57 +0000 Bradley Treeby 4715@http://www.k-wave.org/forum/ <p>Hi deanz1,</p> <p>Do you get this error when running a k-Wave simulation, or when running a simple GPUmat example (e.g., <a href="http://www.k-wave.org/forum/topic/getting-started-with-gpumat">step 6</a>)?</p> <p>Development of GPUmat stopped a couple of years ago, and the latest compiled code is for CUDA 5.0, so it's likely to become increasingly difficult to get it to work. If you have access to the MATLAB parallel computing toolbox, I'd suggest that as the way to go.</p> <p>We will also be releasing a native CUDA code with k-Wave V1.1 sometime in the very near future.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/gpuinfo-invalid-mex-file#post-4703 Wed, 10 Sep 2014 21:33:01 +0000 deanz1 4703@http://www.k-wave.org/forum/ <p>I followed the recipe in "Getting started with GPUmat" in this forum but when I try to run GPUinfo I get:</p> <p>Invalid MEX-file 'C:\Program<br /> Files\MATLAB\R2014a\toolbox\gpumat\bin\GPUinfo.mexw64': The specified module<br /> could not be found.</p> <p>Any idea what this means and how to fix it?</p> <p>Nvidia control panel reports GPU is: GeForce GTX 780 Ti with Driver version 340.62 on Win7-64 bit. </p>
