error when running shell script file in directory examples/03_checkerboard_2d

[ilovesons]

After successfully installing surfatt, I tried to run examples provided in github page.
Examples '00_checkerboard_iso' and '04_hawaii_topo' are executed without any problem,
but when I try to run shell script file in example '03_checkerboard_2d',
I get following messages.

 /output does not contain key "verbose_level".
 Error detected, aborting MPI... proc            0
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
  Proc: [[38992,1],0]
  Errorcode: 30

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
prterun has exited due to process rank 0 with PID 0 on node pago calling
"abort". This may have caused other processes in the application to be
terminated by signals sent by prterun (as reported here).
--------------------------------------------------------------------------

It would be greatly appreciated if you give me a suggestion for solving this problem.
Thanks.
