I was excited that it is in Fortran, but it is in C++. :)

There is a serial Fortran version too. But the code is rather verbose and heavy. It is missing intent specifiers, purity attributes, real constants lack precision specifiers

NVIDIA has featured the C++ benchmark in one of it's Technical Blogs: https://developer.nvidia.com/blog/developing-accelerated-code-with-standard-language-parallelism/

Looks like a great candidate for LFortran automatic modernization. ;) It's not implemented yet, but I created an issue for it.
