v16 v17 10 10 In the online mode of PDAF one couples PDAF to a model into a single assimilation program. With version 1.16 we introduced PDAF-OMI, the [wiki:PDAF_OMI_Overview Observation Module Infrastructure]. The tutorials are adapted for OMI, while tutorials describing the implementation without OMI are provided further below. The implementation is done from the templates provided in /templates/online of the source code package. Two implementations are demonstrated: The case that the model itself is not parallelized and the case that the model is parallelized (i.e. if field is decomposed over several processes). 11 11 12 Step-by-step descriptions of the required implementation steps are provided by the following slide sets (the described features are supported from PDAF 1.16): [[BR]]12 Step-by-step descriptions of the required implementation steps are provided by the following slide sets (the described features are supported from PDAF 2.1): [[BR]] 13 13 * [http://pdaf.awi.de/files/pdaf_tutorial_onlineserial.pdf PDAF Tutorial: Implementation of the assimilation system with a model that is not parallelized] (PDF, 0.9 MB)[[BR]] 14 14 * [http://pdaf.awi.de/files/pdaf_tutorial_onlineparallel.pdf PDAF Tutorial: Implementation of the assimilation system with a parallelized model] (PDF, 0.9 MB)[[BR]] … … 18 18 In the offline mode of PDAF one uses separate programs for the model and the data assimilation. The implementation is done from the templates provided in /templates/offline of the source code package. The tutorial describes the implementation with PDAF-OMI that was introduced with version 1.16. 19 19 20 A step-by-step description of the required implementation steps is provided by the following slide set (the described features are supported from PDAF 1.16): [[BR]]20 A step-by-step description of the required implementation steps is provided by the following slide set (the described features are supported from PDAF 2.1): [[BR]] 21 21 * [http://pdaf.awi.de/files/pdaf_tutorial_offline.pdf PDAF Tutorial: Implementation of the analysis step in offline mode] (PDF, 0.8 MB) 22 22 … … 31 31 With PDAF version 1.16 we introduced PDAF-OMI (Observation Module Infrastructure). We recommend to use this new way to implement observationhandling more efficiently. However, implementing without OMI is still possible and here we provide the tutorial slides for this case: 32 32 33 Step-by-step descriptions of the required implementation steps are provided by the following slide sets (the described features are supported from PDAF 1.16): [[BR]]33 Step-by-step descriptions of the required implementation steps are provided by the following slide sets (the described features are supported from PDAF 2.1): [[BR]] 34 34 Online mode:[[br]] 35 35 * [http://pdaf.awi.de/files/pdaf_tutorial_onlineserial_classical.pdf PDAF Tutorial: Implementation of the assimilation system without OMI with a model that is not parallelized] (PDF, 0.9 MB)[[BR]]
