There was a problem hiding this comment.
Let's lower to 100 or 200 by default, to cover more meta-data heavy cases safer by default.

Is it possible to automatically switch to file based after this OPENPMD_BP5_GROUPENCODING_MAX_STEP ? I will find it annoying to have to restart the simulation due to this limit. |
If you have simulations that run into this limit, that means that you are probably already creating amounts of metadata with a size orders of magnitude more than in a "good" configuration for BP5. Switching to file encoding during a running simulation might be possible, but more effort than it is worth. The proper solution will be to use variable encoding for this kind of setup automatically and I prefer putting my time into making that work properly. |

Check:
In a test simulation with PIConGPU, this canceled the simulation after step 999, creating output that was still readable, but had already accumulated ~1GB of metadata.
