| 106 | The work on the new driver has been picked up since July 2020 by X. W. A short report summarizes the first part of this efforts and can be found on https://forge.ipsl.jussieu.fr/orchidee/attachment/wiki/Documentation/Forcings/nouveau_driver_doc.2.pdf. |

| 108 | A summary of recent progress on the integraton of new driver in the trunk (until the end of 2020): |
| 109 | |
| 110 | * the recent version of new driver from Jan. P is included in the trunk |
| 111 | * fixed a bug when using the forcing file of coarse resolution: corresponding to the ticket https://forge.ipsl.jussieu.fr/orchidee/ticket/575 |
| 112 | * modified several places in orchidee in order that the new driver can be used not only for FG3, but also for spinup analytic and fg1trans. |
| 113 | * identified that the old and the new drivers have the reversed order of latitude when writing the restart file |
| 114 | |
| 115 | Several codes or files were modified and a new script added: |
| 116 | |
| 117 | * fortran code: significant modification to src_driver/forcing_tools.f90, slight change to src_driver/orchideedriver.f90 |
| 118 | * libIGCM : libIGCM/libIGCM_config/libIGCM_config.ksh |
| 119 | * configuration files: COMP/orchideedriver.driver , PARAM/run.def , PARAM/orchidee.def : routing=n (in the tests by using forcing files of coarse resolution) |
| 120 | * A new script AddYears : to prepare for the forcing files, which is to be integrated to the modele/utils. (This script was modified and generalized based a script of Jan). |
| 121 | |
| 122 | |
| 123 | A few remarks in the blow for the knowledge of users of the new driver: |
| 124 | |
| 125 | 1) The new driver need the forcing files of previous, current, and next year. |
| 126 | Suppose that we have forcing files over 1860-2012 and we need run a simulation with the same period, we need forcing files for 1859 and 2013 when using the new driver. The script AddYears is to prepare for such forcing files. |
| 127 | * If we can put the new forcing files into the forcing repository: the users do not need run this script, or modify the data path in .card. Running a simulation with new driver will be the same as the old one, since the good configuration files .card should be in the experiment folder. |
| 128 | * If the additional forcing files are not in the IGCM repository: the users need to: a) run the script AddYears firstly, b) then modify the forcing path in the .card by using the right path to the forcing files before launching simulation. |
| 129 | |
| 130 | 2) The number of MPI is 63 in the config.card by default if using WFDEI 0.5 degree, and it is smaller if using CRU 2degree. So the users should choose the right forcing files for their simulation firstly, and then use a good MPI number. |
