Some benchmarks are here https://pybamm-team.github.io/pybamm-bench/, we should definitely add more PyBaMM's solvers are definitely not optimized for GPUs. Once #1129 is completed that will become more doable |

Thanks, Valentin. I am not sure what I should be looking at in the pybamm-bench link. I was looking at the benchmark list tab and I see a lot of benchmark names but I don't see the python code that users can test out on their systems. I don't see any information on the hardware on which the benchmarks were run. Is there some other link which has this information? The Openmm benchmarks show a comparison of the time to solution for various architectures, I was wondering if there is some information about these PyBaMM benchmarks. |

We don't have anything like that set up. Would be great to have though, if you know how to do it :) |

Thanks Valentin. If we have a repo with a set of problems, users can download them and run them on the machines available to them and submit the information. It will be helpful to the community. AMD EPYC 7542 (AMD Rome) - 1.496GHz Intel(R) Xeon(R) CPU E5-2695 2.10 GHz GPU (A100) If there are some example cases I that I could try to run and post timing results I will be glad to do so. If the problem size can be varied by changing the mesh parameter (as I have done), I can try out some larger cases as well. |

I am not sure what you mean by "creating a platform for people to report results". If people are running the two python codes in the benchmarks link, we can allow them to upload their timings with some information on the cpu or gpu core they are using. Won't that be enough?

We can easily add some more.
If you can take the lead on creating a platform for people to report results that would be amazing. I don't think anyone from the pybamm team has time to do this

Where do you suggest they upload these timings? |

Would it not be possible to have a benchmark tab on the pybamm home-page where users can upload their results. It would be helpful to have select problems on the benchmark page which can be easily downloaded and some blurb on the expected output on successful completion. |

Hello PyBaMMers:
Does anyone know of a reference where the performance of PyBaMM run on a CPU has been compared with the same problem being run on a GPU?
I tried to modify Tutorial 8 (Tutorial 8 - Solver options.ipynb) so it has 320 gridpoints and ran it on a single cpu (AMD EPYC 7542) and then on a A100, the timing was about the same.
Does PyBaMM have any performance benchmarks like those shown in
https://openmm.org/benchmarks
Thanks
Synjon
