# This wrapper uses the NVHPC compiler to build 
# training and inference examples
#
# Need to kick off 2 separate cmake builds with different compilers:
# 1. with GCC, build pytorch C++ wrapper lib that exposes things to Fortran
# 2. with NVHPC, build fortran bindings that just bind(c) to built lib from (1)
# TODO: set path for nvhpc compilers (subshell?)

# Note for installing in Bridges-2 (for CPU support only and intel compilers): Sungduk
# [1] load intelmpi, eg, module load intelmpi/20.4-intel20.4
# [2] activate cmake env for a newer cmake version, eg, conda activate cmake
#     (pytorch, torchvision, cmake, ... are installed in env cmake, Pillow needed some code mod)
# [3] install libtorch (https://pytorch.org/cppdocs/installing.html) -> CMAKE_PREFIX_PATH
