Initializing Domain Decomposition on 32 nodes
Dynamic load balancing: no
Will sort the charge groups at every domain (re)decomposition
Initial maximum inter charge-group distances:
    two-body bonded interactions: 4.558 nm, LJ-14, atoms 742 1195
  multi-body bonded interactions: 4.549 nm, Angle, atoms 742 1176
Minimum cell size due to bonded interactions: 5.013 nm
Guess for relative PME load: 0.06
Will use 30 particle-particle and 2 PME only nodes
This is a guess, check the performance at the end of the log file
Using 2 separate PME nodes, as guessed by mdrun

Fatal error:
There is no domain decomposition for 30 nodes that is compatible with the given box and a minimum cell size of 5.01333 nm
Change the number of nodes or mdrun option -rdd
Look in the log file for details on the domain decomposition
