I'm sure others will find this useful. It seems the DeconvNetToolbox2 also includes precompiled mex files for 64-bit linux in the "/modules/mdz/other/@GPUtype folder", although I haven't tried using these yet.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/gpumat-essential-functions-missing#post-1013 Fri, 16 Nov 2012 12:06:34 +0000 KHO 1013@http://www.k-wave.org/forum/ <p>Hi Brad,</p> <p>actually using the DeconvNetToolbox2 Modules, I was at least able to get it to run on a linux machine, yesterday. Within this box, max, min and some other useful functions are defined that can be integrated into GPUmat. I am not familiar enough with CUDA to figure out why this did not work on windows because in my opinion this should make no difference for the program code.</p> <p>The toolbox (i didn't use anything except for the GPUmat module "other"):<br /> <a href="http://www.matthewzeiler.com/software/DeconvNetToolbox2/" rel="nofollow">http://www.matthewzeiler.com/software/DeconvNetToolbox2/</a></p> <p>This pretty much only has to be copied to the modules directory of GPUmat on a 64 bit machine though it's possible that I had to modify a few include paths for the compilation. They include a matlab make script to use (I believe I had to modify that a little for the CUDA Paths). </p> http://www.k-wave.org/forum/topic/gpumat-essential-functions-missing#post-1007 Wed, 14 Nov 2012 23:16:04 +0000 Bradley Treeby 1007@http://www.k-wave.org/forum/ <p>Hi KHO,</p> <p>Thanks for your feedback and sharing your efforts to get it working. Unfortunately we don't have a simple solution to the missing functions. From my testing notes, these are the current restrictions with using k-Wave and GPUmat:</p> <p>- the option <code>&#39;PlotLayout</code>' must be set to <code>false</code> (no max/min functions)<br /> - the <code>&#39;p_max&#39;</code> and <code>&#39;u_max&#39;</code> options for <code>sensor.record</code> don't work (no max/min functions)<br /> - if using a Cartesian sensor mask with nearest neighbour interpolation, <code>&#39;DataRecast&#39;</code> must be set to <code>true</code> (re-ordering enlarges the output matrix on the fly which is not supported)</p> <p>Perhaps you have also noticed others? </p> <p>The GPUmat toolbox is no longer being actively developed, but the codes have been released open-source (GPL). If you're familiar with CUDA, one option would be to try and add the missing functions to the toolbox.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/gpumat-essential-functions-missing#post-1004 Wed, 14 Nov 2012 16:11:59 +0000 KHO 1004@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I tried using the k-Wave Toolbox with GPUmat. Part of it already runs without any problems but now I came across a missing GPUmat function that seems to break the code. Matlab complains about knowing no function max for data type GPUsingle. When I had a closer look at GPUmat it seemed that there really were a few essential functions missing, i.e. max, min, isnan, isinf, ...</p> <p>So I tried to find a module for GPUmat that would include these, but couldn't really come up with one. I found the DeconvNetToolbox2, which includes GPUmat modules (which also include the missing functions), but even though I could get it to compile the module, it causes Matlab to crash with a Segmentation Fault, when I try using it.</p> <p>How did you solve this problem? One could probably convert to double, do the max(), and then convert back, but that is a rather bad and inefficient solution.</p> <p>This was using Matlab R2011a on Win64 (but I don't think that is the actual problem) and the code was linked to CUDA Toolkit Version 4.2. </p>
