[MITgcm-support] Fatal error in PMPI_Comm_rank: Invalid communicator, error stack

[Srinivasu U]

Dear MITgcm support,

I am trying to run a tutorial example of tutorial_barotropic_gyre

I built it as follows

cd verification/tutorial_barotropic_gyre/build
module unload netcdf/4.2.1
module load netcdf/3.6.3_new
module load openmpi/1.8.4
export NETCDF_ROOT=”/gpfs1/home/Libs/INTEL/NETCDF-3.6.3_new”
export MPI_INC_DIR="/gpfs1/home/Libs/INTEL/OPENMPI/openmpi-1.8.4/include”
../../../tools/genmake2 -enable=mnc -mods ../code -optfile ../../../tools/build_options/linux_amd64_ifort+impi -mpi
make depend
make

cd ../run
ln -s ../input/* .
cp ../build/mitgcmuv .

But while running the model as follows
mpirun -np 4 ./mitgcmuv
I get the following error

Fatal error in PMPI_Comm_rank: Invalid communicator, error stack:
PMPI_Comm_rank(121): MPI_Comm_rank(comm=0x0, rank=0xeea1a4) failed
PMPI_Comm_rank(73).: Invalid communicator

Thanks in Advance.
