Follow instructions for testing edge problems and other tiling issues with
32x32x6 cube sphere configuration.

Baseline 6-tile integration
===========================
cd MITgcm/verification/global_ocean.cs32x15/build
rm *
../../../tools/genmake2 -mods=../code
make depend
rm SIZE.h
cp ../../../../MITgcm_contrib/edge_problem/SIZE.h .
make
cd ..
mkdir run6
cd run6
rm *
cp ../input/* .
cp ../../../../MITgcm_contrib/edge_problem/data.base data
cp ../../../../MITgcm_contrib/edge_problem/tile* .
cp ../build/mitgcmuv .
mitgcmuv > output.txt


Baseline 12-tile integration
============================
cd ../build
rm *
../../../tools/genmake2 -mods="../code_alt/code.12t_32x16 ../code"
make depend
rm SIZE.h
cp ../../../../MITgcm_contrib/edge_problem/SIZE.h_12 SIZE.h

Use matlab to compare Eta for 6-tile and 12-tile integrations
=============================================================
matlab -nojvm -nosplash
f1='run6/Eta.'; f2='run12/Eta.'; tm=72003;
ix=.5:191.5; iy=.5:31.5;
tmp1=readbin([f1 myint2str(tm,10) '.data'],[32*6,32]);
tmp2=readbin([f2 myint2str(tm,10) '.data'],[32*6,32]);
clf, subplot(211)
image(ix,iy,tmp1','CDataMapping','scaled'); colorbar, grid
set(gca,'ydir','normal','xtick',0:32:192,'ytick',0:16:32)
title('Eta, time step 3, 6-tile integration')
subplot(212)
image(ix,iy,tmp2'-tmp1','CDataMapping','scaled'); colorbar, grid
set(gca,'ydir','normal','xtick',0:32:192,'ytick',0:16:32)
title('Difference between 12-tile and 6-tile integrations')
quit


Now repeat with visca4grid
==========================
cd run6
cp ../../../../MITgcm_contrib/edge_problem/data.visca4grid data
mitgcmuv > output.txt
cd ../run12
cp ../../../../MITgcm_contrib/edge_problem/data.visca4grid data
mitgcmuv > output.txt
cd ..


Now repeat with advscheme=33
============================
cd run6
cp ../../../../MITgcm_contrib/edge_problem/data.tempadv data
mitgcmuv > output.txt
cd ../run12
cp ../../../../MITgcm_contrib/edge_problem/data.tempadv data
mitgcmuv > output.txt
cd ..
