Attempting to use an MPI routine before initializing MPICH

[dayon]

Hi, Scientists.
I want to run cesm2.1.3 with a mpi-serial mode. After creating a case, I set the xml file with
./xmlchange NSTASKS=1
./xmlchange MPILIB=mpi-serial
the ./case.build finished with no error. However, when typing the ./case.submit, it failed with the ERROR in the end of cesm.log.201223-103139, as shown:
"Attempting to use an MPI routine before initializing MPICH"

Dose anyone know what else need to be set? Thanks very much in advance.

Hi, I met the same error. Have you solved this problem?

maybe you can set ./xmlchange MPILIB=mpich
