I sent it to your fit email.

Would it be possible to share an input file (or a matlab script to generate it) for this simulation with me? What kind of source do you use? </p> http://www.k-wave.org/forum/topic/cudamemcpy-error#post-7421 Sun, 19 Apr 2020 23:18:04 +0000 ArikHananel 7421@http://www.k-wave.org/forum/ <p>I updated to 1.3 and put the pre-compiled binaries in the k-wave binaries folder and checked the version and got:<br /> <pre><code>+---------------------------------------------------------------+ | kspaceFirstOrder-CUDA v1.3 | +---------------------------------------------------------------+ | Selected GPU device id: 0 | | GPU device name: TITAN RTX | +---------------------------------------------------------------+ | Build information | +---------------------------------------------------------------+ | Build number: kspaceFirstOrder v3.6 | | Build date: Feb 26 2020 | | Build time: 18:12:32 | | Git hash: 468dc31c2842a7df5f2a07c3a13c16c9b0b2b770 | +---------------------------------------------------------------+ | Operating system: Windows x64 | | Compiler name: Visual Studio C++ 1916 | | Processor name: Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz | | Instruction set: Intel AVX | +---------------------------------------------------------------+ | CUDA runtime: 10.2 | | CUDA driver: 10.2 | | CUDA code arch: 7.5 | +---------------------------------------------------------------+ | CUDA device id: 0 | | CUDA device name: TITAN RTX | | CUDA capability: 7.5 | +---------------------------------------------------------------+ | Contact email: <a href="mailto:jarosjir@fit.vutbr.cz">jarosjir@fit.vutbr.cz</a> | | Contact web: <a href="http://www.k-wave.org" rel="nofollow">http://www.k-wave.org</a> | +---------------------------------------------------------------+ | Copyright (C) 2011-2020 SC@FIT Research Group, BUT, Czech Rep | +---------------------------------------------------------------+</code></pre> <p>but I am getting a same error:</p> <p>Running k-Wave simulation...<br /> start time: 19-Apr-2020 18:04:43<br /> reference sound speed: 2820m/s<br /> dt: 7.3052ns, t_end: 397.6583us, time steps: 54436<br /> input grid size: 412 by 236 by 236 grid points (154.5 by 88.5 by 88.5mm)<br /> maximum supported frequency: 2.1067MHz<br /> expanding computational grid...<br /> computational grid size: 432 by 256 by 256 grid points<br /> precomputation completed in 1min 10.6293s<br /> saving input files to disk...<br /> completed in 2min 13.8809s<br /> <pre><code>+---------------------------------------------------------------+ | kspaceFirstOrder-CUDA v1.3 | +---------------------------------------------------------------+ | Reading simulation configuration: Done | | Selected GPU device id: 0 | | GPU device name: TITAN RTX | | Number of CPU threads: 1 | | Processor name: Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz | +---------------------------------------------------------------+ | Simulation details | +---------------------------------------------------------------+ | Domain dimensions: 432 x 256 x 256 | | Medium type: 3D | | Simulation time steps: 54436 | +---------------------------------------------------------------+ | Initialization | +---------------------------------------------------------------+ | Memory allocation: Done | | Data loading: Done | | Elapsed time: 2.90s | +---------------------------------------------------------------+ | FFT plans creation: Done | | Pre-processing phase: Done | | Elapsed time: 2.98s | +---------------------------------------------------------------+ | Computational resources | +---------------------------------------------------------------+ | Current host memory in use: 10177MB | | Current device memory in use: 14421MB | | Expected output file size: 175MB | +---------------------------------------------------------------+ | Simulation | +----------+----------------+--------------+--------------------+ | Progress | Elapsed time | Time to go | Est. finish time | +----------+----------------+--------------+--------------------+ +----------+----------------+--------------+--------------------+ +---------------------------------------------------------------+ | !!!

You need k-Wave V1.3, as Brad suggested, or recompile the code with newer CUDA and include RTX SM architecture in the makefile. </p> http://www.k-wave.org/forum/topic/cudamemcpy-error#post-7388 Mon, 13 Apr 2020 07:35:55 +0000 Bradley Treeby 7388@http://www.k-wave.org/forum/ <p>Can you try with k-Wave V1.3?
