As described in the Rose documentation (e.g. here), and as I've tried to illustrate with my 'pink bubble' drawing here, a Rose suite is composed of apps. JULES Rose suites always have two apps that run sequentially: fcm_make (the compilation step) and jules (actually running the model).
If you prefer to understand this in a more UNIX way, see screenshot right: the JULES Rose suite is simply a directory on your file system (at location $RSUITE in my notes) that contains some files (including the textfile suite.rc) and two subdirectories app/fcm_make/ and app/jules/ .
- For former UMUI users, suites and apps are what used to be called jobs and tasks.
- The config file for the jules app contains all the namelist files described on the JULES manual pages (select your version of JULES and find section "The JULES namelist files").
- For where to get hold of an example Rose suite for running JULES, see here. Also, note that all Rose suites are also available via the repository (e.g. my one u-am539).
- The suite.rc textfile controls how the apps of the suite relate to each other and the order in which they are run. You can specify complex and repeating runs of JULES using this (see e.g. here for using it to loop through a set of JULES runs with changing parameter settings). If you want to know more about how to use this, see the Suite Design Guide and/or Kerry Smout-Day's tutorials on the JULES manual pages.
