CICE with dynamics allocatable through namelist
One of my test using GX3 (24 iterations):
CICE_v6/GX3> md5sum history./icednc
1b47affe3502c4e9354691c22785c916 history.AllocDyn/iced.1998-01-02-00000.nc
1b47affe3502c4e9354691c22785c916 history.master/iced.1998-01-02-00000.nc
--o--
INFO:
New namelist info (and default values):
&domain_nml
nprocs = -1
max_blocks = -1 ! MXBLCK
block_size_x = -1 ! BLCKX
block_size_y = -1 ! BLCKY
nx_global = -1 ! NXGLOB
ny_global = -1 ! NYGLOB
...
CICE stops with ERROR if the namelist settings are <1 - except for max_blocks. If max_blocks is <1 it is automatically calculated/estimated as:
max_blocks=( ((nx_global-1)/block_size_x + 1) * ((ny_global-1)/block_size_y + 1) ) / nprocs

TIP: If you want to keep the CPPDEFS to specify blocks, grid size etc., You can add a "sed" command similar to this:
cat ice_in_tmp | sed s/'^.nprocs.$'/" nprocs = ${nprocs}"/g
| sed s/'^.max_blocks.$'/" , max_blocks = ${MXBLCK}"/g
| sed s/'^.block_size_x.$'/" , block_size_x = ${BLCKX}"/g
| sed s/'^.block_size_y.$'/" , block_size_y = ${BLCKY}"/g
| sed s/'^.nx_global.$'/" , nx_global = ${NXGLOB}"/g
| sed s/'^.ny_global.$'/" , ny_global = ${NYGLOB}"/g > ice_in
MXBLCK can be set to 0. The it is calculated as:
max_blocks = (nx_global/block_size_x)*(ny_global/block_size_y) / nprocs
(as suggested within ice_domain_size.F90)
