Introduction
This section shows how to configure and run OpenIFS and XIOS together.
First of all, it is necessary that OpenIFS is compiled with XIOS (see OpenIFS: Enable XIOS during compilation) and the XIOS executable is available in the experiment directory. OpenIFS should be run as usual (see 6.3 OpenIFS Running a Forecast), but adding the argument '--xios' to oifs_run. This will use by default 1 XIOS server, but in case of needing more servers, it can be done with '--xios --xios-nproc <arg>'.
It is also necessary to enable the LXIOS switch in the NAMCT0 namelist (fort.4 file).

Please note: as XIOS is not used operationally at ECMWF, we can only provide help on a best effort basis. We encourage users to post questions on XIOS to the OIFSUF to get help from other users in the OpenIFS community. |
