   Hi,the k-wave toolbox is very nice.

   But I'v recently got some problem about simulation in a very large scale,

   First of all,while using kspaceFirstOrder3DG to simulate,I could get sensor_data with the k-space gird setting 128 * 128 * 128.However,I got a error "Not enough memory to run the simulation" with the k-spece grid setting 1792 * 1792 * 1792.I have 8 GPUs on my computer with 40GB memory per each,I think k-wave only used one GPU without using other 7.Is there any way for me to use all the 320 GB memory on 8 GPUs to simulate one k-wave?

   Second,I can use kspaceFirstOrder3DG to simulate my own k-wave code correctly on windows.However there would be some errors when running on linux,I guess k-wave 1.4 toolbox with c++ 1.3 has not compiled with A100 yet.I failed to re-compile the C++,Luckily,I got a re-compiled C++ cuda execute program on github and then it could run correctly. And I wish if the C++ code could have some new GPU-version support.

   I would really appreciate it if you can help me with the First problem!

   Zhao Xiang,You can get the re-compiled cuda exe on this address——https://github.com/InesConceicao/Binary-k-Wave.git,But it is a linux version.

   By the way,can we have some communication on personal email?My email is hexu92026@gmail.com.

   I hope to talk to you as soon.

   k-Wave is still running only on a single GPU, however, the multi-GPU version is almost finished and will be released in Sept 2023.

   Anyway, 1792 * 1792 * 1792 is far too big, it would consume about 650GB of GPU memory. With 8 A100, 40GB of memory, our alpha code was able to run up to 1280^3

   @Jiri Jaros,

   Are you and your team still on track to release a multi-GPU version this month? Do you have an updated timeline?

   We're very keen to use it :)
