This page presents a data base of optimal partitionings
which can be used to benchmark heuristic sparse matrix partitioners
for their quality in terms of communication volume
of a parallel sparse matrix-vector multiplication. This page is under perpetual construction.
New matrices will be added as we go.
Currently we have a batch of **839 optimally bipartitioned matrices**
(and a few more). Comments are welcome.
The main focus of the page is bipartitioning, but there is a section
with results for small matrices partitioned into *p=3* or *p=4* parts.

The data base accompanies the following papers for *p=2*:

exact algorithm for sparse matrix bipartitioning,

*Journal of Parallel and Distributed Computing*,**85**(2015) pp. 79-90. Postprint version - An

*Parallel Computing*,**96**(2020) Article 102640. Postprint version

The data base accompanies the following paper for *p=3, 4*:

- Engelina L. Jenneskens and Rob H. Bisseling, Exact k-way sparse matrix partitioning, Proceedings 12th IEEE Workshop Parallel/Distributed Combinatorics and Optimization (PDCO'22), June 2022, accepted for publication.

The initial set of 355 solutions for *p=2* has been obtained by the program MondriaanOpt,
developed by Daan Pelt and Rob Bisseling,
which is included as a tool in the Mondriaan package, but
is a separate program with a separate version number.
It uses the matrix reading functions of Mondriaan,
but is otherwise self-contained (so that its correctness can be verified
independently).
MondriaanOpt v1.0 has been included in
Mondriaan v4.1,
released November 7, 2016.

A larger set of 839 solutions has been
obtained for *p=2* by an improved program called MP (MatrixPartitioner) with stronger bounds
developed by Timon Knigge,
which is available from GitHub,
matrix partitioner MP.
The optimal communication volumes computed by both programs are the same.
(This has been verified for all 368 matrices that both could solve.)

A set of 114 small matrices has been partitioned for *p=3*
and a set of 100 matrices for *p=4*
using an Integer Linear Programming (ILP) method,
by Engelina Jenneskens, who also developed the General Matrix Partitoner (GMP)
based on the branch-and-bound method
for this purpose. Her software is available from GitHub,
General Matrix Partitoner GMP.
The optimal communication volumes computed by both methods are the same,
as verified for the matrices that both could solve.

The partitioning results in the table and picture gallery
below are for bipartitionings,
i.e. for *p=2* processors.
The main reason is that heuristic partitioners are often based on
recursive bipartitioning, which thus determines the overall quality
of the partitioning.
Furthermore, exact algorithms can only solve small problems to optimality
within a reasonable time,
and problems for 2 processors are easier to solve
than those for more processors.
Still, a limited set of results has also been computed for *p=3, 4*.
Symmetric matrices stored in lower triangular form are first expanded to the full sparse matrix,
which also includes the nonzeros of the upper triangle.
Symmetry is not imposed in the partitioning.

The allowed imbalance is ε = 3%, which is a value commonly used
in the literature for testing partitioners of sparse matrices, graphs, and
hypergraphs. Having a single value keeps the database limited in size.
Results for any other desired value of ε can be obtained by
running the MondriaanOpt program or the program MP with that value as input parameter.
The allowed imbalance is defined by the constraint

*nz(A[i])* ≤
*(1+ ε) ceil(nz(A)/p)*, for *i=0,1,...,p-1.*

Here, *nz(A)* is the number of nonzeros of the matrix *A*
and *nz(A)[i]* the number of nonzeros assigned to processor *P(i)*.
The ceiling is taken to guarantee that a feasible solution always exists,
also for ε= 0.
Note that
this differs slightly from the formula without the ceiling
commonly used in heuristic solvers. To compare solutions, the input value of ε
has to be adapted for the heuristic solvers.

The solutions given were obtained using an ILP method implemented in IBM ILOG CPLEX 20.1 software and running on a 4.3 GHz AMD 3800 XT processor with 8 cores and 16 threads and 16 GB RAM.

Two Comma Separated Values files ilp_solutions_p=3.csv and ilp_solutions_p=4.csv present all the statistics of the solutions by the ILP method The CSV file can easily be handled by a spreadsheet program for further analysis. The columns are as follows: matrix name, number of rows m, number of columns n, number of nonzeros nz, number of nonempty rows, number of nonempty columns, communication volume CV, imbalance, time of GMP (in s), time of ILP (in s).

The results for *p=2* are presented in two different ways: a set of files containing the solution
by MP of a batch of 839 matrices, and a picture gallery presented as a table
containing the initial set of 355 matrices obtained by using MondriaanOpt.

A Comma Separated Values file mp_solutions.csv presents all the statistics of the solutions by MP in the same format as the table of the picture galley, see below. The CSV file can easily be handled by a spreadsheet program for further analysis. The number of rows and columns in the CSV file is the number after removal of empty rows and columns. Thus these numbers may be less than the original numbers. The timings in the CSV file are given in seconds.

The solutions themselves, i.e., the bipartitioned matrices, are collected in a single file mp_matrices.tar.gz in gzipped tar format. The file size is 24 Mbyte, but it expands to a directory with a total size of 845 Mbyte when uncompressed. The directory contains the matrices as a textfile (with extension .mtx-I2f) giving the partitioning. Images of the bipartitioned matrices are collected in a single file mp_SVG.tar.gz in gzipped tar format. The file size is 59 Mbyte, but it expands to a directory with a total size of 1.4 Gbyte when uncompressed. The images are given in .svg format. The .mtx-I2f and .svg formats are described below.

- Name: matrix name in the SuiteSparse sparse matrix collection. If the same matrix name (like `football') appears in two different matrix groups, the group name is also given. If you click on the name you get the details from the SuiteSparse page.
- Rows: number of matrix rows (
*m*). - Columns: number of matrix columns (
*n*). - Nonzeros: number of nonzero matrix elements (
*nz*). Note that explicitly stored zeros are also treated as nonzeros. See e.g. bcsstm01 which has 24 explicitly stored zeros. - Volume: communication volume in a parallel sparse matrix-vector multiplication (in data words).
- Imbalance: achieved imbalance, expressed as the difference between the maximum number of nonzeros per processor and the minimum.
- Solution: link to the solution given as an integer matrix in
Matrix-Market format, with a header line,
one line of the form
*m*,*n*,*nz*, and then*nz*lines of the form

*i j proc*

where*i*is the row number of a nonzero,*j*the column number, and*proc*the processor number assigned by the solution, either 1 for processor P(1), or 2 for processor P(2), or a special value 3 meaning the nonzero is**free**, so that it can be assigned either way, to P(1) or P(2), without affecting communication. Still, their assignment must satisfy the load imbalance constraint (e.g. for the matrix jgl009, at least one of the free nonzeros in row 4 must be assigned to P(2), blue, as here the constraint requires perfect balance). Free nonzeros can be assigned such as to give the best possible load balance. The matrix name is extended by the postfix -I2f, to denote that the matrix has been partitioned into 2 parts, and that free nonzeros are displayed. The numerical values of the original matrix are discarded. The processor numbering is 1-based, in line with the Matrix-Market conventions, and to facilitate plotting by Matlab. - Date: date when the solution has been added to the table, in dd-mm-yyyy format. Keeps track of history.
- Mond means MondriaanOpt was used to produce the solution. MP means the MatrixPartitioner program MP was used. Mond/MP means MondriaanOpt was used, and MP was used to verify the volume bound.
- Time: time needed to solve the problem, either less than a second, minute, hour, day, week, month, year, decade on the current computer used. This is only a rough indication, as it depends on the initial upper bound on the volume given (for MondriaanOpt, the volume obtained by a run of the medium-grain method from Mondriaan v4.0 +1; for MP, trying increasing upper bounds, each time multiplying a failed bound by a factor 1.25) and the computer used (for MondriaanOpt, 1 core of an Apple iMac with 3.4 GHz Intel Core i5 processor; for MP, 1 core of a 2.4 GHZ Intel Ivy Bridge E5-2695 v2 processor).
- Picture: a picture in Scalable Vector Graphics (SVG) format with red nonzeros corresponding to P(1), blue nonzeros to P(2), and yellow ones to the free nonzeros. For matrices that are too large (nz >1000) to show within the table in SVG format, you have to click on a link to see the picture. For matrices that are very large (nz > 100000), the picture will most likely not display on your browser.
