Specifics for using C ESM EP at CNRM

See C-ESM-EP doc home page first.

Since August, 2018, C-ESM-EP runs at CNRM, out of the box, as described in The-C-ESM-EP-in-a-nutshell, with few specifics :

1. You should install branch adapt_to_CNRM by
   • cd /cnrm/<my_team>/USERS/<my_account>/<some subdir>
   • git clone -b adapt_to_CNRM https://github.com/jservonnat/C-ESM-EP.git
2. It uses cluster aneto behind the curtain for computing atlas ; hence, you must first setup your environment for working with aneto – see page 20 of the Aneto user manual. This implies that all data must be available on the CNRM Lustre /cnrm (and also the C-ESM-EP sotfware, see above)
3. Locations for atlas and climaf cache are set in file locations.py (at C-ESM-EP root) ; you must adapt it top your case; see comments there ; default values are :
   • All atlas : /cnrm/est/USERS/username/NO_SAVE/C-ESM-EP
   • Climaf cache : /cnrm/est/USERS/username/NO_SAVE/CESMEP_climaf_cache
4. Atlas will be displayed in browser using urls such as ‘file:///’ (rather than http://); this because there is no uniform way across teams to use a file system which would be accessible by an http server
5. The reference observations datasets are a copy of those on Ciclad, which is updated from time to time (it is located at /cnrm/est/COMMON/climaf/reference_datasets_from_IPSL)
6. CMIP6 data organized according to CMIP6 DRS on /cnrm/cmip6 are duly configured
7. For now :
   • some components of 'standard_comparison' are not yet working : Monsoons, ORCHIDEE, ParallelCoordinates_Atmosphere
   • Note a special feature : you can de-activate a component by un-setting read permission on the corresponding directory or params.py file `
