Chunk lance
Chunk_lance
Chunk_lance allows to run a sequence of monthly model jobs in one big job.
A GEM/GEMCLIM/CRCM5 simulation usually consists of a sequence of month jobs.
Each monthly job is made up out of 3 parts:
- auto_launch (copies restart files from previous month, prepare config files for new month)
- entry (only in LAM mode, prepares driving data)
- model (main model job)
Chunk_lance will run a series of these 3 jobs, checking at the end of each model job if there is still enough time to calculate another month. If yes the 3 jobs will get executed for another month, if not an new chunk_job will get submitted.
In case the model job fails it will automatically get reexecuted up to 4 times.
