#1628 closed Bug (fixed)

bug when key_mpp_mpi is not active

Reported by: clem Owned by: nemo
Priority: low Milestone:
Component: OCE Version: release-3.6
Severity: Keywords:


Multiple communications (lbc_lnk_multi) have not been coded when key_mpp_mpi is inactive. Since these communications are present in dynspg_ts and limrhg, the model crashes when running orca2-lim3 (for example).

Therefore I propose to modify lbclnk.F90 (as shown in the attached file). It looks to me the easiest way to deal with this issue but additional expertise would be appreciated

I think we have 2 open tickets of these. We developed an alternative version, without load_array, and only calling to lbc_lnk single from the lbc_lnk_2d_9. We only created lbc_lnk_2d_multiple because is called directly from limhdf in the new optimization, but in fact it only does a loop with the different variables.

Maybe your approach is more elegant, but in fact in serial mode it has any benefit to perform the packing, and our code is a little bit simpler (and with less number of lines).
