MInimum size of mpp subdomain uncorrectly set for AGRIF zooms

Reported by: jchanut Owned by: systeam
Priority: low Milestone:
Component: AGRIF Version: release-4.0
Severity: minor Keywords:
Cc:

Description

Context

AGRIF does not work for too small mpp subdomains (defined as the sum of the ghosts cells + the sponge layer width + one line/column of zeros)

Analysis

Uncomplete stop statement in agrif_nemo_init

Recommendation

Modify stop in agrif_user routine such that:

jpi/jpj > 1 + nbghostcells + (nn_sponge_len * raf + 1)


e.g., since nn_sponge = 2 and nbghost = 3, if raf=1 (as in the 1st zoom of AGRIF_DEMO reference configuration), jpi/jpj > 7
This restriction will be relaxed in the forthcoming release.

adjust AGRIF decomposition domains (from 32 to 16 procs) in SETTE REPRO tests to avoid zoom domain sizes < 8 pts (see #2322 for details) → all SETTE ref configs tests OK with trunk @ r11761 in O0 at Mercator
