Well spotted @psychocoderHPC .
Yes, we allow for a basic *static load balancing* with the flags `--gridDist`, see [here](https://github.com/ComputationalRadiationPhysics/picongpu/blob/dev/doc/TBG_macros.cfg#L72-L75).

If I am not totally mistaken, the class `SubGrid` should give you your local position in the global grid and its local size.
