4 Orange partition

Each partition is an ensemble of segments in the global domain. Each segment is described by its global offset and its local extent. In this case, we have ig_paral(1:N) where N = 2 + 2*number of segments

Figure 2.5 illustrates an Orange partition with 3 segments for one process. The other process partitions are not illustrated.
