Running and Verification

Use PuTTY to log in to the server as the root user.
Run the following command to start a benchmark test:
```
cd /path/to/MOM/MOM6-examples/ocean_only/benchmark/
```

Run the following commands to modify the case scale:

cat << EOF >> MOM_override 
#override NIGLOBAL = 720
#override NJGLOBAL = 360
EOF

Run the following commands to modify the case time:

cat << EOF >> input.nml
 &ocean_solo_nml
        months = 0
        days = 20 /
EOF

Run the following command to create a RESTART directory:
```
mkdir RESTART
```
Run the following command to start a benchmark test:
```
{ time -p mpirun --allow-run-as-root -np 128 -mca btl ^openib ../../build/gnu/ocean_only/repro/MOM6 > mom.log ;} 2>>mom.log
```
View the value of real in the mom.log log. A smaller value indicates a higher performance.

Figure 1 shows an example output.
