To restart a simulation one need needs to :

1) Make sure the restart files of the previous month is under ~/MODEL_EXEC_RUN/$TRUE_HOST

...

3) Edit the file 'chunk_job.log'

As you hopefully know, each simulated month consists of two scripts:

• a very short                             Script-job : ${GEM_exp}_S
• followed by one of more Model-jobs : ${GEM_exp}_M

To know where the simulation wasis, Chunk_lance is using a log file called 'chunk_job.log'. The chunk_job itself will check this file to determine which job to execute next. Therefore, this log file should usually not be touched.
However, to rerun part of a simulation one can alter the log file by hand. Just make sure there is never a blank line at the end of the log file 'chunk_job.log' since the chunk_job only checks the very last line of the log file!

Restart using Chunk_lance

In case a simulation stops and you want to find out which job (scripts, entry or model) crashed, you have have look in the listings directory (~/listings/${TRUE_HOST}). Check which of the following jobs has crashed:

...

'chunk_job.log' contains entries like the following:

Each completed month has at least 4 entries:

To restart a month make sure the last line either contains:

    ... current_month_S starting ...
or
    ... previous_month_M finished ..

...

.

Restart from previous restart file
