Dear gromacs developers,
The HIP version of gromacs 2018.7 that I mentioned in my last email yesterday is now avaliable on https://github.com/ipe-zhangyz/hipified-gromacs-2018.7
I have tested it only on Rocm 2.8.13 and AMD MI50 GPUs because I don't have other test environment.
Please have a try if you are interested. My configuration commands are in the config.sh file in the top dir of the project. Before you run the cmake configuration, maybe you need to modify the --amdgpu-target parameter in src/gromacs/CMakeLists.txt to satisfy your AMD GPU.
Any feedback is welcome!
Sincerely,
Zhang

You can find more details about HIP on https://github.com/ROCm-Developer-Tools/HIP. Currently gromacs runs on AMD GPU via OpenCL,but the performance of the OpenCL version may be worse than the CUDA version.

I have tested it on AMD MI50 GPUs and get 10%~30% better performance on some test cases than the OpenCL code of gromacs 2019.3. I want to know if there is any official plan to develop HIP version gromacs, or anyone else who is interested in this work.
