This would create the ob01 forecast directories for a single date. The default is to create the experiment directory in your 'scratch' directory with the same name as the experiment id. e.g $HOME/scratch/ob01.
New experiment: ob01 - single data,
...
10 members
Following the creation of the initial files for the experiment id 'ob01' given above, let's create a forecast experiment with 5 ensemble members for a single forecast date:
| Code Block | ||
|---|---|---|
| ||
troifs0@cca-login3:~> createEX -d 2015110100 -e ob01 -i scratch/inidir -m 49 |
| Info |
|---|
Note, one ensemble member '00' (or a 'control') is always created, so the -m argument gives the number of additional ensemble forecasts. Only use 10 members in total otherwise you will not be able to compare with the climatological SST experiment which uses 10 members. |
This generates the output:

For our 'ob01' experiment, this command would create all the jobs, correctly configure the namelist and submit the job. There will be 5 10 jobs, one forecast for each ensemble member:
...
Setting the ensemble member
The command 'run_all_ens' does this step, no action is needed. This section explains the use of the ensemble member number by IFS.
...
Create and submit Cray batch job
This step is done by the run_all_ens command. No user action is needed. This section provide more information on the oifs_run command.
