Login to ECMWF Cray
Each participant will have a training user account on the ECMWF Cray system. This is different from the user account on the classroom computers.
Begin by logging onto the Cray login nodes:
ssh trcray1@ccb Password: xxxxxxxx trcray1@ccb-login2:~>
The contents of the account should look like:
trcray1@ccb-login2:~> ls bin modules.sh oifs38r1 scratch
If any are missing please let us know.
Directory: oifs38r1
This directory contains the OpenIFS source code and the model executable.
For this purpose of this workshop, the model has already been compiled to avoid waiting and adding unnecessary load to the login nodes.
Examine the oifs38r1 directory.
Directory: scratch
This is the directory in which we will run OpenIFS.
Setting the correct environment
Each time you login and before doing any work in this account, make sure you have the correct environment loaded to run and work with OpenIFS.
source modules.sh
Creating the OpenIFS ensemble experiment
Using : createENS .....
Control forecast : cf000
perturbed forecast : pf001
You will run the perturbed forecast (you can run the control later)
Creating the OpenIFS batch job
Using : oifs_run .....
Editing the namelist
cp namelistfc fort.4

Problems
CRTABLEDIR set wrong. Model stops and prints error.
FDB still enabled. Model prints no error. Enable OIFS_DUMMY_ACTION=abort to see error.
Set length of run to d10 - model will stop and print error that the climate file is too short.
