---|
2 | !!---------------------------------------------------------------------- |
---|
3 | !! *** ROUTINE mpp_init2 *** |
---|
4 | !! |
---|
5 | !! * Purpose : Lay out the global domain over processors. |
---|
6 | !! FOR USING THIS VERSION, A PREPROCESSING TRAITMENT IS RECOMMENDED |
---|
7 | !! FOR DEFINING BETTER CUTTING OUT. |
---|
8 | !! This routine requires the presence of the domain configuration file. |
---|
9 | !! In this version, the land processors are avoided and the adress |
---|
10 | !! processor (nproc, narea,noea, ...) are calculated again. |
---|
11 | !! The jpnij parameter can be lesser than jpni x jpnj |
---|
12 | !! and this jpnij parameter must be calculated before with an |
---|
13 | !! algoritmic preprocessing program. |
---|
14 | !! |
---|
15 | !! ** Method : Global domain is distributed in smaller local domains. |
---|
16 | !! Periodic condition is a function of the local domain position |
---|
17 | !! (global boundary or neighbouring domain) and of the global |
---|
18 | !! periodic |
---|
19 | !! Type : jperio global periodic condition |
---|
20 | !! nperio local periodic condition |
---|
21 | !! |
---|
22 | !! ** Action : nimpp : longitudinal index |
---|
23 | !! njmpp : latitudinal index |
---|
24 | !! nperio : lateral condition type |
---|
25 | !! narea : number for local area |
---|
26 | !! nlci : first dimension |
---|
27 | !! nlcj : second dimension |
---|
28 | !! nproc : number for local processor |
---|
29 | !! noea : number for local neighboring processor |
---|
30 | !! nowe : number for local neighboring processor |
---|
31 | !! noso : number for local neighboring processor |
---|
32 | !! nono : number for local neighboring processor |
