60    Instructions for generating 1-CPU and 2-CPU executables
61    =======================================================
62    
63    Generating 1-CPU executable:
64      cd MITgcm/verification/lab_sea
65      mkdir build
66      cd build
67      ../../../tools/genmake2
68      make clean
69      make depend
70      make
71      mv mitgcmuv mitgcmuv_1
72    
73    Generating 2-CPU executable:
74      cd ../code
75      \mv SIZE.h SIZE.h_1
76      \mv SIZE.h_mpi SIZE.h
77      ../../../tools/genmake2 -mpi
78      make clean
79      make depend
80      make
81      mv mitgcmuv mitgcmuv_2x1
82    
83    
84    Instructions for running Experiment 1
85    =====================================
86    
87    This is a 1-cpu, 10-hour integration used to make sure that all
88    the files are available and that the sea-ice model compiles and
89    runs.  The reading of atmospheric forcing files and the computation
90    of open-water bulk fluxes are carried out within pkg/seaice.
91    
92    To run Experiment 1:
93      cd ../input
94      ./mitgcmuv_1 >&! output.txt
95    
96    Use matlab script lookat_exp1.m to compare the output
97    of exp1 with that from checkpoint51f sea-ice code:
98      cd ../../../verification/lab_sea/matlab
99      matlab
100      lookat_ice
101    
102    
103    Instructions for running Experiment 2
104    =====================================
105    
106    This is a 2-cpu, 10-hour integration.
107    
108    To run Experiment 2:
109      cd ../../../verification/lab_sea/input
110      mpirun -np 2 mitgcmuv_2x1
