The first gives satisfactory results while for the second I have the impression that there is an inversion of the X and Y axes of the source grid and/or of the sensor grid. Could you confirm the problem for me?<br /> thanks in advance </p> http://www.k-wave.org/forum/topic/error-kwave-cuda-3dg-p_source_input-has-wrong-dimension-size-iostream-error#post-9103 Fri, 14 Jun 2024 19:33:56 +0000 Drainville1 9103@http://www.k-wave.org/forum/ <p>Any update on the labelled source mask? Is there any way to reduce the size/dimension of source.p when using a large number of source points, that could otherwise be represented by a single signal for each unique element? </p> http://www.k-wave.org/forum/topic/error-kwave-cuda-3dg-p_source_input-has-wrong-dimension-size-iostream-error#post-8054 Sun, 07 Feb 2021 08:36:08 +0000 Bradley Treeby 8054@http://www.k-wave.org/forum/ <p>Hi carljiri,</p> <p>Ok, that makes sense now. The use of a labelled source mask is an experimental feature and not fully supported (I thought it wasn't supported at all in the C++/CUDA versions, but I'd need to go back and check). In a future version this will be more widely supported, but in a different format that also allows scaling. </p> <p>Brad. </p> http://www.k-wave.org/forum/topic/error-kwave-cuda-3dg-p_source_input-has-wrong-dimension-size-iostream-error#post-8053 Sat, 06 Feb 2021 21:48:17 +0000 carljiri 8053@http://www.k-wave.org/forum/ <p>Hey,<br /> it contains 0 for no mask<br /> and 1,2,3,4,5,6,7,8</p> <p>it gets really strange now.</p> <p>on the nvidia 2080 i can calculate it using cuda binaries. on the 3090, it crashes, but every other calculation where i got only 1 signal for all elements i can run on the 3090.</p> <p>i will try do delete the kwave toolbox and install them again on the 3090 server on monday. maybe it fixes the problem. </p> http://www.k-wave.org/forum/topic/error-kwave-cuda-3dg-p_source_input-has-wrong-dimension-size-iostream-error#post-8051 Sat, 06 Feb 2021 17:37:52 +0000 Bradley Treeby 8051@http://www.k-wave.org/forum/ <p>Just to clarify, does <code>p_mask</code> contain numbers 1 to 8, or just the numbers 1 and 0? </p> http://www.k-wave.org/forum/topic/error-kwave-cuda-3dg-p_source_input-has-wrong-dimension-size-iostream-error#post-8050 Sat, 06 Feb 2021 15:18:32 +0000 carljiri 8050@http://www.k-wave.org/forum/ <p>Hey :) </p> <p>all elemements are present in the 3D array. where the element exists index == number of the element. so inner circle ==1 to most outer circle == 8. </p> <p>so i got everything from 1 to 8 in its....(p_mask)</p> <p>and in the source_p i got 8 rows of shifted signals. </p> http://www.k-wave.org/forum/topic/error-kwave-cuda-3dg-p_source_input-has-wrong-dimension-size-iostream-error#post-8045 Sat, 06 Feb 2021 12:24:28 +0000 Bradley Treeby 8045@http://www.k-wave.org/forum/ <p>Hi carljiri,</p> <p>Does source.p have the same number of signals as the <code>sum(source.p_mask(:))</code>?</p> <p>Brad </p> http://www.k-wave.org/forum/topic/error-kwave-cuda-3dg-p_source_input-has-wrong-dimension-size-iostream-error#post-8035 Mon, 01 Feb 2021 17:30:50 +0000 carljiri 8035@http://www.k-wave.org/forum/ <p>Hey,<br /> thanks for the great tool. </p> <p>i simulate 3D a bowl shaped focused transducer which consists out of 8 ring elements.<br /> i got a problem for phase shift/focus shift simulation.</p> <p>I use Matlab 2019a<br /> Kwave Cuda 1.3<br /> gtx 3090</p> <p>I create 8 different signals for the 8 elements with time delayed signals.<br /> i is the number of the element: source.p(i, :) = filterTimeSeries(kgrid, medium, sig);</p> <p>If i use kspaceFirstOrder3D Simulation, it works perfect but needs 25 minutes with gpuarray-single for one simulation. </p> <p>If i use 3DG for cuda i got this error: Dataset p_source_input has wrong dimension size. iostream error Matlab also Puts out errors: h5readc (not found or unsupported characters) </p> <p>If i dont use phase shift, and only give 1 signal to the source for all elements. 3DG works perfect and fast and calculates everything in 90 seconds. </p> <p>so 90seconds vs 25 min is a huge difference for me. </p> <p>Maybe someone knows how to fix this porblem or did i miss, that this is not possible. </p>
