Hi Van Thinh,

In your "data" file, you probably want to set:

 nIter0 = INSERT_NUMBER_HERE,

where INSERT_NUMBER_HERE is the model iteration number of the last time
step from the previous run that you would now like to "pick-up" from in
the next run.  There are many examples of how to start from pick-up (or
"checkpoint") files in our verification suite.

A quick way to find these examples is:

  cd MITgcm/verification
  grep -i iter0 */input/data

which will give you a list of about 30 data files that contain the
nIter0 option.
