Code coupling using OASIS

nasri |  0 comment |  

Deadline for registration: 15 days before the starting date of each training
Duration : 2 days / (14 hours)




The OASIS coupler, developed over the past 20 years at CERFACS, is a software allowing synchronized exchanges of coupling information between numerical codes representing different components of the climate system.

Objective of the training

The objectives of this course are to help the participants how to use OASIS and install it on their own computing platforms.

Learning outcomes

On completion of this course, you will be able to :

·   implement OASIS3-MCT API in a simplified coupled model (toy model)

·   list the steps to be taken to interface OASIS3-MCT API in your own code

·  evaluate the quality of oasis interpolation on your grid pairs

Target participants

This training session is for engineers, physicists, computer scientists and numerical analysts wishing to use this code coupling software in their own coupled model.


In order to follow this course, you need to:

·         be familiar with the use of basic Linux commands,

·         master Fortran,

·         master the basic MPI commands.

In order to verify that the prerequisites are satisfied, the following questionnaire must be completed. You need to get at least 75% of correct answers in order to be authorized

to follow this training session. If you don’t succeed it, your subscription will not be validated. You only have two chances to complete it.

  • Trainees/PhDs/PostDocs : 140 €
  • CERFACS shareholders/CNRS/INRIA : 400 €
  • Public : 800 €**

** The training will be half price (400 €€ out of taxes instead of 800 €€ out of taxes) for the first 4 European participants registered due to explicit financing by a European project.


Every day from 9h to 17h30

Day 1

The session will start with a general presentation of OASIS and with a tutorial during which the participants will be guided step-­by-­step through the compilation and running (on CERFACS training room PCs) of a toy coupled model reproducing coupling exchanges between two pseudo models, testing different functionalities of the coupler.

Day 2

The participants will be introduced to a specific running environment developed to assess the quality of OASIS interpolations and will be invited to use it with their own model grids. Finally, the participants will install OASIS on their own computing platforms, if accessible through remote connection, and if time allows, they will start interfacing OASIS in their own model codes. This crucial step in setting up a real coupled model will be achieved more efficiently if the participants master their codes.

Final examination

A final exam will be conducted during the training.
