In particular, besides the communicator, it contains the data relevant !! to the following queries: !! !! - How many global rows/columns? !! !! - How many local rows/columns? !! !! - Convert between local and global indices !! !! - Add to local indices. !! !! - Find (one of) the owner(s) of a given index !! !! - Query the indx state. !! !! - Does the dynamic class support extensions of the rows? I.e., can !! it have overlap? for instance, the BLOCK cannot, it would run afoul !! of the glob_to_loc translation. !! !! Checking for the existence of overlap is very expensive, thus !! it is done at build time (for extended-halo cases it can be inferred from !! the construction process). !! !! The object can be in the NULL, BUILD or ASSEMBLED state. !! !! Rules/constraints: !! !! 1. Each global index I is owned by at least one process; !! !! 2. On each process, indices from 1 to N_ROW (desc%indxmap%get_lr()) !! are locally owned; the value of N_ROW can be determined upon allocation !! based on the index distribution (see also the interface to CDALL). !! !! 3. If a global index is owned by more than one process, we have an OVERLAP !! in which case the sum of all the N_ROW values is greater than the total !! size of the index space; !! !! 4. During the buildup of the descriptor, according to the user specified !! stencil, we also take notice of indices that are not owned by the current !! process, but whose value is needed to proceed with the computation; these !! form the HALO of the current process. Halo indices are assigned local indices !! from N_ROW+1 to N_COL (inclusive). !! !! 5. The upper bound N_COL moves during the descriptor build process (see CDINS). !! !! !! This is the base version of the class; as such, it only contains !! methods for getting/setting the common attributes, whereas !! the index translation methods are only implemented at the derived !! class level. !! Note that the INIT method is defined in the derived methods, and !! is specialized for them; a better solution would have to have !! a constructor for each specific class, with the name of the class, !! but this is not yet working on many compilers, most notably GNU. !! !! Note: the CLONE method was implemented as a workaround for a problem !! with SOURCE= allocation on GNU. Might be removed later on. !! type :: psb_indx_map !> State of the map integer(psb_ipk_) :: state = psb_desc_null_ !> Communication context type(psb_ctxt_type) :: ctxt !> MPI communicator
