I agree that the GPU capabilities of the Parallel Computing Toolbox are currently in their infancy. However, many institutions have site-wide licenses to MATLAB that include access to this toolbox. This is particularly relevant for students who may not be able to purchase a separate license to the Accelereyes product. We are not planning to deprecate compatibility with Jacket (it is a nice product and integrates well with k-Wave). Rather, we plan to add additional compatibility with <code>GPUArray</code>. I'll post some benchmarking results back here when we start working on this!</p> <p>Kind regards,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/parallel-computing-toolbox#post-351 Mon, 05 Mar 2012 21:17:54 +0000 soundmaster 351@http://www.k-wave.org/forum/ <p>I've done a lot of benchmarking of Jacket vs the Parallel Computing Toolbox, and Jacket always ends up much faster. PCT GPU rarely even beats the CPU in my benchmarks. Jacket on a laptop is faster than PCT on a Tesla, <a href="http://www.walkingrandomly.com/?p=4062" rel="nofollow">http://www.walkingrandomly.com/?p=4062</a></p> <p>I say forget the PCT GPU and stick with what is actually fastest. </p> http://www.k-wave.org/forum/topic/parallel-computing-toolbox#post-350 Sat, 03 Mar 2012 01:24:00 +0000 Bradley Treeby 350@http://www.k-wave.org/forum/ <p>Hi Chao,</p> <p>It seems that R2012a has included <code>bsxfun</code> and <code>fftn</code> in the list of GPU functions supported by the Parallel Computing Toolbox. We'll work towards supporting <code>&#39;DataCast&#39;</code> set to <code>&#39;GPUArray&#39;</code> for the next release.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/parallel-computing-toolbox#post-275 Mon, 09 Jan 2012 01:09:03 +0000 Bradley Treeby 275@http://www.k-wave.org/forum/ <p>Hi Chao, </p> <p>In principle, yes. However, the current release of the parallel computing toolbox (2011b) only supports a small number of GPU functions. As this expands to include <code>bsxfun</code> and <code>fftn</code> we will definitely add support for k-Wave to utilise this toolbox. We also plan to release an optimised C/C++ version of the 3D simulation function (which will work in conjunction with the MATLAB codes). On a modern multicore CPU, this runs almost as fast as MATLAB + GPU. </p> <p>Brad. </p> http://www.k-wave.org/forum/topic/parallel-computing-toolbox#post-274 Sun, 08 Jan 2012 17:34:07 +0000 huangchao 274@http://www.k-wave.org/forum/ <p>Hi,</p> <p>Instead of using the Jacket toolbox for GPU computing in the k-Wave version b04, could I use the <a href="http://www.mathworks.com/discovery/matlab-gpu.html">Parallel Computing Toolbox</a> to do the same thing?</p> <p>Thanks,<br /> Chao </p>
