When loading an ADIOS2 bp5 openPMD dataset with particle density using the FromOpenPMDImpl density functor the simulation freezes while executing this functor when the dataset is written with the file based iteration encoding, but it loads without any problem if the iteration encoding is groupBased. This is somewhat strange since the group based enconding is the one that is supposed to be bug-prone.
This happens on perlmutter with:
- recent picongpu dev
- openpm-api 0.16.1
- adios2 2.10.2
Could this be somehow related to #5510? This is read and not write, but not all ranks have to loadChunk in FromOpenPMDImpl (and not all were loading in my setup).
