Thanks a lot! </p> http://www.k-wave.org/forum/topic/2d-ccuda-code#post-3931 Tue, 24 Sep 2013 01:27:17 +0000 ouelletn 3931@http://www.k-wave.org/forum/ <p>Thanks Brad,<br /> For my case it is mostly the number of simulations that need to be run, as there are multiple possible setups and imaging types I want to experiment with. I will likely be upgrading my hardware and just wanted to know if these were being developed before I make decision to purchase something that may not be necessary. Thanks again though. </p> http://www.k-wave.org/forum/topic/2d-ccuda-code#post-3928 Thu, 19 Sep 2013 15:35:55 +0000 Bradley Treeby 3928@http://www.k-wave.org/forum/ <p>Hi Andrew,</p> <p>We have no immediate plans to release 2D C++ codes, largely because the compute times using MATLAB or MATLAB+GPU are already quite short. Do you have an application in mind where minimising the compute time is critical?</p> <p>You could certainly run 2D simulations using the 3D C++ code using a small value for <code>Nz</code> (e.g., <code>Nz = 3</code>). You will need to duplicate your source (e.g., <code>source.p0</code> or <code>source.p_mask</code>) in the third dimension, and turn off the PML using the optional inputs <code>&#39;PMLSize&#39;, [10, 10, 1]</code> and <code>&#39;PMLAlpha&#39;, [2, 2, 0]</code>. However, this will definitely be slower than using an optimised 2D code due to the redundant calculations in the third dimension.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/2d-ccuda-code#post-3925 Wed, 18 Sep 2013 22:50:19 +0000 ouelletn 3925@http://www.k-wave.org/forum/ <p>I was just wondering if there is any plans to release a 2D version of the C++ code or Cuda code, or can this be done using an infinite plane approach along one dimensions? If my understanding is correct the 2D case should be a subset of the 3D, although I worry about making this assumption and do not know if it would be slowed down as compared to a 2d code implementation.</p> <p>Thanks,<br /> Andrew </p>
