 If this happens, please add `-fallow-argument-mismatch` in the compile include file in `make.arch` to the line 'OPT = ....'.
 gfortran from version 10 checks the arguments more strictly than older versions of gfortran. The apparent argument mismatch is actually allowed in the call to functions of MPI.

+== What does 'PE' and 'PE-local' in the code mean? ===
+
+'PE' is the common expression for 'processing element'. This relates to parallelization and usually refers to a single process or 'task' in MPI parallelization. Thus, when you read 'PE-local' in the source code, this means that some variable is local (specific) or a single process or MPI task (thus while the variable usually exist for all processes, its value can be different for each process).
