_It looks like Nvidia changed
something in the CUDA Toolkit with version 12.2 on Windows. I have tried
12.2, 12.3, and 12.4, and they all fail to compile bellhopcuda, while 12.1
seems to work. Unfortunately, I'm required to use 12.2 or higher at work. I
have also tried it on a Linux machine with 12.3, and it compiles. I get
screens full of compilation errors relating to chrono conversions (e.g.,
C:\Program Files\NVIDIA GPU Computing
Toolkit\CUDA\v12.2\include\cuda\std\detail\libcxx\include\chrono(906): error
: class "cuda::std::__4::commontype<double, double>" has no member "type").
I'm guessing that you are using nvcc's chrono for timing the parts of the
run. I'm attaching part of the error log in case it's helpful (the full
thing was ~40k lines at 6 MB). This almost seems like an nvcc issue, but
hopefully there's a workaround.
