Hi,
For GROMACS 2025, there are two ways to use modern AMD GPUs:
- GMX_GPU=HIP (build instructions); in the mainline GROMACS release, only limited number of tasks can be offloaded to the GPU.
- GMX_GPU=SYCL (build instructions, Ubuntu-specific step-by-step guide); this version is feature-complete.
SYCL/AdaptiveCpp is the recommended approach, but both are supported. Choose whichever suits you best.
Please provide more details on how you build GROMACS and the full error text. libredscale.so is not something GROMACS itself uses.
