|
|
!
|
|
! This is the most important data structure: it holds all the data
|
|
! necessary to organize data exchange. The pattern of communication
|
|
! among processes depends not only on the allocation of portions of
|
|
! the index space to the various processes, but also on the underlying
|
|
! mesh discretization pattern. Thus building a communication descriptor is
|
|
! very much linked to building a sparse matrix (since the matrix sparsity
|
|
! pattern embodies the topology of the discretization graph).
|
|
!
|
|
! This is a two-level data structure: it combines an INDX_MAP with
|
|
! a set of auxiliary lists.
|
|
! For a complete description of INDX_MAP see its own file, but the
|
|
! idea here is the following: the INDX_MAP contains information about
|
|
! the index space and its allocation to the various processors.
|
|
! In particular, besides the communicator, it contains the data relevant
|
|
! to the following queries:
|
|
! 1. How many global rows/columns?
|
|
! 2. How many local rows/columns?
|
|
! 3. Convert between local and global indices
|
|
! 4. Add to local indices.
|
|
! 5. Find (one of) the owner(s) of a given index
|
|
! 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).
|
|
! There are multiple ways to represent an INDX_MAP internally, hence it is
|
|
! a CLASS variable, which can take different forms, more or less memory hungry.
|
|
!
|
|
! Guidelines
|
|
!
|
|
! 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).
|
|
!
|
|
! 6. The descriptor also contains the inverse global-to-local mapping.
|
|
!
|
|
! 7. The data exchange is based on lists of local indices to be exchanged; all the
|
|
! lists have the same format, as follows:
|
|
! the list is composed of variable dimension blocks, one for each process to
|
|
! communicate with; each block contains indices of local elements to be
|
|
! exchanged. We do choose the order of communications: do not change
|
|
! the sequence of blocks unless you know what you're doing, or you'll
|
|
! risk a deadlock. NOTE: This is the format when the state is PSB_ASB_.
|
|
! See below for BLD. The end-of-list is marked with a -1.
|
|
!
|
|
!| notation stored in explanation
|
|
!| --------------- --------------------------- -----------------------------------
|
|
!| process_id index_v(p+proc_id_) identifier of process with which
|
|
!| data is exchanged.
|
|
!| n_elements_recv index_v(p+n_elem_recv_) number of elements to receive.
|
|
!| elements_recv index_v(p+elem_recv_+i) indexes of local elements to
|
|
!| receive. these are stored in the
|
|
!| array from location p+elem_recv_ to
|
|
!| location p+elem_recv_+
|
|
!| index_v(p+n_elem_recv_)-1.
|
|
!| n_elements_send index_v(p+n_elem_send_) number of elements to send.
|
|
!| elements_send index_v(p+elem_send_+i) indexes of local elements to
|
|
!| send. these are stored in the
|
|
!| array from location p+elem_send_ to
|
|
!| location p+elem_send_+
|
|
!| index_v(p+n_elem_send_)-1.
|
|
!
|
|
! This organization is valid for both halo and overlap indices; overlap entries
|
|
! need to be updated to ensure that a variable at a given global index
|
|
! (assigned to multiple processes) has the same value. The way to resolve the
|
|
! issue is to exchange the data and then sum (or average) the values. See
|
|
! psb_ovrl subroutine.
|
|
!
|
|
! 8. When the descriptor is in the BLD state the INDEX vectors contains only
|
|
! the indices to be received, organized as a sequence of entries of
|
|
! the form (proc,N,(lx1,lx2,...,lxn)) with owning process, number of indices
|
|
! (most often but not necessarily N=1), list of local indices.
|
|
! This is because we only know the list of halo indices to be received
|
|
! as we go about building the sparse matrix pattern, and we want the build
|
|
! phase to be loosely synchronized. Thus we record the indices we have to ask
|
|
! for, and at the time we call PSB_CDASB we match all the requests to figure
|
|
! out who should be sending what to whom.
|
|
! However this implies that we know who owns the indices;
|
|
! this is actually only true for the OVERLAP list
|
|
! that is filled in at CDALL time, and not for the HALO (remember: we do not
|
|
! necessarily have the space to encode the owning process index); thus
|
|
! the HALO list is rebuilt during the CDASB process
|
|
! (in the psi_ldsc_pre_halo subroutine).
|
|
!
|
|
! 9. Yet another twist comes about when building an extended descriptor with
|
|
! the psb_cdbldext subroutine. In this case we are reaching out
|
|
! layer by layer, but we may use the results in two ways:
|
|
! i. To build a descriptor with the same "owned" indices, but with an
|
|
! extended halo, with additional layers; in this case the requests
|
|
! go into halo_index;
|
|
! ii. To build a descriptor suitable for overlapped Schwarz-type computations.
|
|
! In this case we end up with more "owned" indices than in the base
|
|
! descriptor, so that what was a halo index in the base becomes an overlap
|
|
! index in the extended descriptor. In this case we build three lists:
|
|
! ovrlap_index the indices that overlap
|
|
! halo_index the halo indices (of the extended descriptor)
|
|
! ext_index the indices of elements that need to be gathered to
|
|
! map the original index space onto the new (overlapped)
|
|
! index space.
|
|
! So, ext_index has the same format as the others, but is only used in the
|
|
! context of Schwarz-type computations; otherwise it is empty (i.e.
|
|
! it only contains the end-of-list marker -1).
|
|
!
|
|
! 10. ovrlap_elem contains a list of overlap indices together with their degree
|
|
! of overlap, i.e. the number of processes "owning" the, and the "master"
|
|
! process whose value has to be considered authoritative when the need arises.
|
|
!
|
|
! 11. ovr_mst_idx is a list defining a retrieve of a copy of the values for
|
|
! overlap entries from their respecitve "master" processes by means of
|
|
! an halo exchange call. This is used for those cases where there is
|
|
! an overlap in the base data distribution.
|
|
!
|
|
! It is complex, but it does the following:
|
|
! 1. Allows a purely local matrix/stencil buildup phase, requiring only
|
|
! one synch point at the end (CDASB)
|
|
! 2. Takes shortcuts when the problem size is not too large
|
|
!
|
|
! 3. Supports restriction/prolongation operators with the same routines
|
|
! just choosing (in the swapdata/swaptran internals) on which index list
|
|
! they should work.
