   A week ago, I struggled to run the C++ version of k-Wave on the latest hardware. After spending some time and using existing resources from the forum, I was able to overcome the issue. So, I created this repository with a comprehensive guide for both Windows and Linux. I hope it helps others.

   Thank you very much! I’ll review it and consider incorporating it into the official version. I also plan to update the manual to include a time comparison with newer GPUs. :)

   Additionally, I noticed that GCC 13+ compilers have changed how infinity is handled. The following lines now cause the simulation to end with NaNs.

   if (absorbNabla1[i] == std::numeric_limits<float>::infinity()) absorbNabla1[i] = 0.0f;
   if (absorbNabla2[i] == std::numeric_limits<float>::infinity()) absorbNabla2[i] = 0.0f;

   a simple, however, not the best fix is:

   // Comparison with infinity is not supported with --ffast-math enabled
   if (absorbNabla1[i] >= std::numeric_limits<float>::max()) absorbNabla1[i] = 0.0f;
   if (absorbNabla2[i] >= std::numeric_limits<float>::max()) absorbNabla2[i] = 0.0f;
