> That’s very valuable data, thanks for sharing! Can you please clarify what does “unstable” mean for gfx1100? If you encountered some errors it would be good to know about them (so we can fix them)!

This has been mentioned in the main text:

> However, when it comes to the gfx1100 (RDNA 3) GPU, operation stability is a concern across all three versions of ROCm. Specifically, performance fluctuations and a high probability of mdrun getting stuck after running for a period of time have been observed (similar feedback was reported on the GROMACS forum in June of this year). Furthermore, GPU status information cannot be recognized by rocm-smi in this case.

I think the unstability is due to the fact that AMD ROCm does not yet officially support RDNA3. Two months ago someone posted a similar issue on this forum: [GROMACS get stuck AMD GPU](https://gromacs.bioexcel.eu/t/gromacs-get-stuck-amd-gpu/6625)
