We have an OpenACC application that can be built with NVIDIA's HPC toolkit. Our aim is to port this code to port this Fortran + HIP C++. In this report, we consider the code DYNAMICO.

GPUFORT is a python tool. It depends on a number of python packages. Applications ported with GPUFORT have a number of dependencies that must be installed on the host system. One of the dependencies is HIPFORT.

To install HIPFORT, we first need to download the latest hipfort (main or development branch).

• Main branch:

git clone [email protected]:RocmSoftwarePlatform/hipfort.git

• Development branch:

git clone [email protected]:RocmSoftwarePlatform/hipfort.git -b develop

Next we install HIPFORT to /opt/rocm/hipfort (recommended) via cmake. As usually with cmake, we first create a build subfolder in the hipfort directory:

cd hipfort
mkdir build

This will result in the following HIPFORT directory structure:

hipfort/
├── bin
├── build
├── cmake
│   └── Modules
├── lib
│   ├── hipfort
│   └── modules-amdgcn
└── test
    ├── f2003
    └── f2008

We enter the build subfolder and install HIPFORT via:

cd build
cmake -DHIPFORT_INSTALL_DIR=/opt/rocm/hipfort ../
make -j<num_proc>
make install

Finally, we add the HIPFORT installation's bin directory to the PATH:

export PATH=$PATH:/opt/rocm/hipfort/bin

We can test the PATH setting via, e.g.:

hipfc -h

You can test HIPFORT itself by following the steps in https://github.com/ROCmSoftwarePlatform/hipfort/blob/master/README.md

When GPUFORT is publicly available, you can use the following commands to donwload GPUFORT and the OpenACC runtime interfaces:

• Download GPUFORT:
