[MITgcm-support] s12t_16x32

[Amitabh Mitra]

 Dear Sir,

 I was trying to run the sea ice experiment

 s12t_16x32 in SGI Origin.

 It is a sea ice experiment downloaded 
 
 from the website below

 http://dev.mitgcm.org/cgi-bin/viewcvs.cgi/MITgcm_contrib/high_res_cube/code-mods/s12t_16x32/

 The readme found in the Code-Mods directory is

 attached with this mail.

 All the program files required for running

 the experiment (as mentioned in the Readme) are 

 not present in the website e.g.

 exch2_xyz_rl.F and all exch2... files.

 I think this is the reason for getting errors.

 Also I downloaded the latest MITgcm_checkpoint58.tar.gz

 but this time I am not able to create 'mitgcmuv'.

 So how can I get all the missing program files and remove errors.

 Thanking You,

 With Regards,

 Amitabh Mitra

The following files have currently been added or customized for general topology communications.

TBD 
  o for general _RS _RL support the .template forms of exch_ and exch2_ need modifying/creating.
  o MDS based I/O needs to be modified to use tile base coodinates and not to assume a funcional relationship
    between nsx, snx etc...

Directories holding example SIZE.h, w2_e2setup.F and W2_EXCH2_TOPOLOGY.h are
as follows. Examples are all for a cs32 index space with different tile sizes.
Until mdsio is fixed to understand tiling only s6t_32x32/, 
s24t_8x32/ and s12t_16x32/ are allowed for runs that rely on global
datasets for input (bathymetry, forcing, pickups etc..) because the cube
global file mode only looks like the cartesian form when sny is the same as
the cube size. However, it is possible to arbitrary size tile runs when using 
tiled input files.

s12t_16x32/                   # 12 tiles of size 16x32
s24t_16x16/                   # 24 tiles of size 16x16 (I/O not available)
s24t_32x8/                    # 24 tiles of size 32x8  (I/O not available)
s24t_8x32/                    # 24 tiles of size  8x32 
s6t_32x32/                    #  6 tiles of size 32x32
s60t_51x510                   # 60 tiles of size 51x510
