| subroutine, public | amr_rebalance |
| Cost-weighted rebalance without refine/coarsen. For static/uniform grids (refine_max_level=1) amr_coarsen_refine never runs, so the cost-weighted load_balance has no invocation point and the partition stays at the initial equal-block (cell-count) split -> photosphere EoS-heavy ranks stall the rest. This migrates blocks to equalise the measured per-block cost (block_cost, populated when lb_automatic is on) then rebuilds connectivity + ghosts, mirroring the tail of amr_coarsen_refine. | |
