This is a new implementation of BabelStream using Fortran.
The code uses a Fortran driver that is largely equivalent to the C++ one, with a few exceptions. First, it does not use a C++ class for the stream object, since that doesn't seem like a useful way to do things in Fortran. Instead, I use a module that contains the same methods, and which has alloc and dealloc that act like CTOR and DTOR.
The current implementations are:
- DO CONCURRENT
- Fortran array notation
- Sequential DO loops
- OpenACC parallel loop
- OpenACC kernels on Fortran array notation
- OpenMP parallel do
- OpenMP taskloop
- OpenMP target teams distribute parallel do simd
- OpenMP target teams loop
- CUDA Fortran (handwritten CUDA Fortran kernels, except DOT)
- CUDA Fortran kernels (!$cuf kernel do <<<*,*>>>)
I have tested with GCC, Intel (ifort and ifx), and NVHPC compilers on AArch64, x86_64 and NVIDIA GPU targets, although not exhaustively. Cray and Fujitsu have been tested as well. The only untested compiler of significance is IBM XLF.
The current build system is GNU Make, and requires the user to manually specify the compiler and implementation.
CSV printing is supported.

add check for normal (not NaN, not Inf, not denormal)
the previous error check failed to detect garbage results because comparisons against NaN always return true.
i flipped the logical comparison and added a check for IEEE normal to prevent this. it works on the case that was missed previously.
