Detailed Description

Class that manages the octree mesh.

Since, the input octree represents elements sorted based on the Morton ordering, we need to created a sorted list of nodes. All nodes in the balanced octree, except for hanging nodes and positive boundary nodes, are associated with exactly one element (octant) in octree. Psuedo-elements are created for all the additional nodes, which are marked. This can be done with a single linear pass ($\mathcal{O}( n / p )$) followed by a parallel sort ($\mathcal{O}( n / p \log n / p )$)). We get two major benefits from this. Firstly, we store only one ordering for both the elements and the nodes, and the size of the combined array is $\Theta ( 2 n )$ for an input balanced octree of $n$ elements. Secondly, we are now in a position to compress this data structure, from one utilizing 4 int to only one char per node. On systems with 4 byte words, this translated to a 16x compression. The algorithm does not add any overheads for in order iterations over either the nodes or the elements.

Only one char (8 bits) is stored per element/node. This stores a number of things, including the level of the element (5 bits), whether it is a Node (N, 1-bit), whether it is a Boundary node (BN, 1-bit), and whether it is a dependent element(DE, 1-bit). A dependent element is one which has at least 1 node, which is owned by another processor. Whether the element/node is a ghost or not can be determined purely by it's index.

The bit structure for this char is

N BN DE LEVEL

where the highest bit determines whether it is an element or not.

Random access into the elemental/nodal array is however not currently possible, and should not be required. The DA can be extended if required to support random access, by having additional markers, for every $k$ nodes, within the nodal array, which will enable searching in $\mathcal{O}( \log n / k + k )$ and increase storage by $3 n / k$ int. For the search to be efficient, we will need to choose $k$ such that $k = \log n$. This will allow us to search within the DA in $\mathcal{O}( \log n )$, but will increase storage from $\Theta ( 2 n )$ to $\Theta ( 2 n + 12 n / \log n )$.

In addition we need the neighbourhood data to be prepared for each element/node. In case of and elemental iteration, we need to store the information pertaining to the 7 additional nodes (in 3D) defining this hexahedral element. In the case of a node-based iteration, we will need to store the information about 26 neighbouring nodes, connected to this node via adjacent elements.

The major issue with this is the storage of the indices, which is 8 times the number of nodes in the octree. In order to reduce storage costs only the offsets from the current index are stored. In addition, these offsets are compressed by using a variant of the Golomb-Rice encoding.

In order to overlap computation and communication, it is preferable that the Finite Element calculations be done in two stages. The communication is initialized first, and simultaneously we process the independent elements. We then wait for the communication to finish before processing the dependent element. A sample loop will look like,

 // Start communication 
 readFromGhostsBegin(array, true); 
 // Process independent elements 
 for ( init<ot::DA_FLAGS::INDEPENDENT> ;
      curr() < end<ot::DA_FLAGS::INDEPENDENT>(); 
      next<ot::DA_FLAGS::INDEPENDENT>() ) { 
     // process current element ...
 } 
  
 // wait for communication to end.
 readFromGhostsEnd(); 
  
 // Now process the dependent elements 
 for ( init<ot::DA_FLAGS::DEPENDENT>; 
        curr() < end<ot::DA_FLAGS::DEPENDENT>(); 
        next<ot::DA_FLAGS::DEPENDENT>() ) { 
      // process current element ...
 }

Constructor & Destructor Documentation

ot::DA::DA (  std::vector< ot::TreeNode > &  in,
MPI_Comm  comm,
MPI_Comm  inputActiveComm,
bool  compressLut = false,
const std::vector< ot::TreeNode > *  blocksPtr = NULL,
bool *  iAmActive = NULL
) 
 

The constructor that builds the DA from a Sorted, Linear, Complete, 2:1 Balanced, Octree.

Author:
Hari Sundar

Rahul Sampath

Parameters:
comm The MPI communication context which is to be used for setting up the DA.
iAmActive If an address is provided then the status of the calling processor is returned in that address. 'true' if the mesh is distributed on the calling processor and 'false' otherwise.
blocksPtr If this parameter is NOT NULL, then the input is assumed to be a valid partition of the octree that can be used for the mesh as it is. If this parameter is NULL, then a fresh partition is computed inside the constructor itself. Typical users should pass NULL for this parameter.
compressLut Pass 'true' to compress the element-to-node mappings using Goloumb-Rice encoding and 'false' otherwise. Note that uncompressing these mappings during the Matvecs will incur a small overhead.
in The sorted, complete, linear, 2:1 balanced octree that is to be used for constructing the DA.
inputActiveComm An MPI_Comm consisting of only those processors which call the constructor with an non-empty 'in' vector. This is a subset of comm, which can be got by calling the function par::splitComm2way.
The constructor builds the DA based on the input octree. It constructs all the required neighbour information and also (optionally) compresses the structure to reduce the memory footprint.

int ot::DA::setValuesInMatrix (  Mat  mat,

a wrapper for setting values into the Matrix. This internally calls PETSc's MatSetValues() function.

Author:
Rahul Sampath

Parameters:
mat The matrix
records The values and their indices
dof the number of degrees of freedom per node
mode Either INSERT_VALUES or ADD_VALUES
Returns:
an error flag Call PETSc's MatAssembly routines to assemble the matrix after setting the values. 'records' will be cleared inside the function. It would be more efficient to set values in chunks by calling this function multiple times with different sets of values instead of a single call at the end of the loop. One can use the size of 'records' to determine the number of such chunks. Calls to this function with the INSERT_VALUES and ADD_VALUES options cannot be mixed without intervening calls to PETSc's MatAssembly routines.

In addition, this operation is required to use the oda based indexing. vecRestoreBuffer() must be called when the buffer is no longer needed. If isReadOnly is true, this involves a simple copy of local values from in. The ghosts will have junk value in this case. If isReadOnly is false, the buffer will be zeroed out first and then the local values from in will be copied. The ghosts will have 0 values in this case.
