---|
159 | !! in mpp configuration in case of jpn1 > 1 and for 2d |
---|
160 | !! array with outer extra halo |
---|
161 | !! |
---|
162 | !! ** Method : North fold condition and mpp with more than one proc |
---|
163 | !! in i-direction require a specific treatment. We gather |
---|
164 | !! the 4+kextj northern lines of the global domain on 1 |
---|
165 | !! processor and apply lbc north-fold on this sub array. |
---|
166 | !! Then we scatter the north fold array back to the processors. |
---|
167 | !! This routine accounts for an extra halo with icebergs |
---|
168 | !! and assumes ghost rows and columns have been suppressed. |
