obelix : error in main job header when using more than 1 node

Reported by: jgipsl Owned by: sdipsl
Priority: major Milestone: libIGCM_v2.6 metrics

Description

Quand on dépasse 16 cpu MPI, l'entête du job est mal remplis.

Par exemple avec JobNumProcTot=32, on obtient

#PBS -l nodes=1:ppn=32

Mais les nœuds contient 8 ou 16 procs. On a 2 possibilité pour 32 proc :

#PBS -l nodes=2:ppn=16
#PBS -l nodes=4:ppn=8

Selon F. Marabelle, le mieux c'est le 2'eme choix.

To solve this properly we need ins_job to be aware of the MPI and OpenMP situation. Currently ins_job is filling up the header but dont have any clue on parallelism. To me it is related to the openMP integration and testing ticket : #96

We need to redesign and to refactor IGCM_sys_build_execution_scripts. To be honest this function is a bit messy and very heterogeneous between plateforms.

Close that one. This is link to #96 and a better management of headers in different MPI/OMP geometry
