! package: psb_gen_block_map_mod
! Defines the GEN_BLOCK_MAP type.
!
! It is the implementation of the general BLOCK distribution,
! i.e. process I gets the I-th block of consecutive indices.
! It needs to store the limits of the owned block, plus the global
! indices of the local halo.
! The choice is to store the boundaries of ALL blocks, since in general
! there will be few processes, compared to indices, so it is possible
! to answer the ownership question without resorting to data exchange
! (well, the data exchange is needed but only once at initial allocation
! time).
