BDD Benchmarking Suite

This is a collection of benchmarks for Binary Decision Diagrams (BDDs) [Bryant1986] and some of its variants. These are useful to survey the strengths and weaknesses of different implementations and to guide their developers. To this end, each benchmark is implemented by use of C++ templates such that they are agnostic of the BDD package used.

This project has been developed at the Logic and Semantics group at Aarhus University.

Decision Diagrams

Our benchmarks target the following types of decision diagrams.

BDD Packages

The benchmarks are implemented using C++ templates to make them agnostic of the BDD package used. To do so, each implementation has an adapter in-between which is fully inlined at compile time. Currently, we support the following BDD packages.

  • Adiar [Sølvsten2022]:

    An I/O-efficient implementation based on [Arge1995] with iterative algorithms that use time-forward processing [Arge1996, Chiang1995] to exploit a special sorting of BDD nodes streamed from and to the disk. These algorithms have no need for memoization or garbage collection. But, on the other hand, nodes are also not shareable between BDDs.

  • BuDDy [Lind-Nielsen1999]:

    An easy-to-use yet extensive implementation of shared BDDs with depth-first algorithms using a unique node table and memoization.

    We use this version that has been updated and builds using CMake.

  • CAL [Sanghavi1996]:

    A breadth-first implementation based on [Ochi1993, Ashar1994] that exploits a specific level-by-level locality of nodes on disk to improve performance when dealing with large BDDs. Unlike Adiar it also supports sharing of nodes between BDDs at the cost of memoization and garbage collection.

    We use the revived version with an extended C API, CMake support and a C++ API.

  • CUDD [Somenzi2015]:

    Probably the most popular BDD package of all. It uses depth-first algorithms and a unique node table and memoization.

    We use this modified v3.0 with CMake support and an extended C++ API.

  • LibBDD [Beneš2020]:

    A thread-safe implementation with depth-first algorithms and memoization. Yet unlike others, it does not implement shared BDDs, i.e., two diagrams do not share common subgraphs. Hence, the unique and memoization tables are neither reused between operations.

    We use this unofficial Rust-to-C FFI.

  • OxiDD [Husung2024]:

    A multi-threaded (and thread-safe) framework for the implementation of decision diagrams and their algorithms. Currently, its algorithms are depth-first on a unique node table and memoization.

  • Sylvan [Dijk2016]:

    A multi-threaded (and thread-safe) implementation with depth-first algorithms using a unique node table and memoization.

Dependencies

All packages use CMake to build. This makes compilation and linking very simple. One merely has to initialize all submodules (recursively) using the following command.

git submodule update --init --recursive

To build, one needs CMake and a C++ compiler of your choice. On Ubuntu, one can obtain these with the following command:

apt install cmake g++

The Picotrav benchmark requires GNU Bison and Flex. On Ubuntu, these can be installed with.

apt install bison flex

The McNet benchmark requires the Boost Library. On Ubuntu, these can be installed as follows

apt install libboost-all-dev

Adiar

Adiar also has a transitive dependency on the Boost Library. On Ubuntu, these can be installed as follows

apt install libboost-all-dev

LibBDD and OxiDD

These libraries are implemented in Rust and interact with C/C++ via an FFI. Hence, one needs to use cargo which in turn requires an internet connection to download the dependency crates during the first build ("crate" is the Rust term for a package).

There are different ways to install Rust. On all platforms, it is possible to use the official installer script for rustup, the toolchain manager. Some OSes also provide a rustup or rustup-init package. If you have rustup installed, then you can install the latest stable Rust toolchain (including cargo) using rustup default stable. Some OSes also provide a fairly recent Rust package. On Ubuntu, you can simply install cargo via:

apt install cargo

Furthermore, the libraries depend on cbindgen to generate a C header from Rust code. cbindgen can either be installed through Cargo or your OS package manager. Note however, that a relatively recent version of cbindgen is required (we tested 0.26.0, which is not provided by Ubuntu versions prior to 24.04).

cargo install --force cbindgen

Note

If installing cbindgen through cargo, remember to update your PATH. Otherwise, CMake will abort with an "Could not find toolchain ''" error. You can obtain the path from the print message during cargo install which states "warning: be sure to add <THE_PATH> to your PATH ..."

Usage

When all dependencies have been resolved (see above), you can build and run the benchmarks as follows.

Build

To configure the CMake project run:

cmake -B build

The default settings can be changed by also parsing various parameters to CMake. Here are the values that might be relevant.

  • -D CMAKE_BUILD_TYPE=<Release|Debug|RelWithDebInfo|...> (default: Release)

    Change the build type. Except for development purposes, leaving it at Release is propaly the most correct choice.

  • -D CMAKE_C_COMPILER=<...>, -D CMAKE_CXX_COMPILER=<...>

    Select a specific C/C++ compiler.

  • -G <Generator>

    Select the build generator; on most systems, Makefile would be the default. To speed up the build process you may want to try to use Ninja instead.

Features of the benchmarks and BDD packages can also be turned on and off as follows

  • -D BDD_BENCHMARK_INCL_INIT=<OFF|ON> (default: OFF)

    If ON, includes the initialization time of the BDD Package in the total running time.

  • -D BDD_BENCHMARK_STATS=<OFF|ON> (default: OFF)

    If ON, build with statistics. This might affect performance.

  • -D BDD_BENCHMARK_WAIT=<OFF|ON> (default: OFF)

    If ON, pause before deinitialising the BDD package and exiting. This can be used to investigate its state with external tools, e.g., use of Hugepages.

After configuring, you can build the benchmarks:

cmake --build build

Run

After building, the build/src folder contains one executable for every possible combination of BDD library, benchmark, and DD kind. Not all libraries support every kind of DD (see above) and not all benchmarks are available for BDDs/BCDDs or ZDDs.

The executables follows a <Library>_<Benchmark>_<DD> naming scheme (each of the three components in nocase). All executables have a common command line interface to configure the BDD library in question:

  • -h

    Print a help text with all options (including the ones particular to that particular benchmark).

  • -M <int> (default: 128)

    Amount of memory (in MiB) to be dedicated to the BDD library.

    Note, that the memory you set is only for the BDD package. So, the program will either use swap or be killed if the BDD package takes up more memory in conjunction with the benchmark's auxiliary data structures.

  • -P <int> (default: 1)

    (Maximum) worker thread count for multi-threaded BDD libraries, e.g., OxiDD and Sylvan.

  • -R

    Enable dynamic variable reordering (if available with said BDD package).

  • -T <path> (default: /tmp, /usr/tmp/, ...)

    Filepath for temporary files on disk for external memory libraries, e.g., Adiar.

For example, you can run the Queens benchmark on Sylvan with 1024 MiB of memory and 4 threads as follows:

./build/src/sylvan_queens_bcdd -M 1024 -P 4

Furthermore, each benchmark requires options. See -h or the Benchmarks Section for details.

Benchmarks

Apply

Based on [Pastva2023], this benchmark loads two (or more) decision diagrams stored in a binary format (as they are serialized by the LibBDD library) and then combines them with an Apply operation (or more).

The benchmark can be configured with the following options:

  • -f <path>

    Path to a .bdd / .zdd file. Use this once for each input. You can find some inputs in the benchmarks/apply folder together with links to larger and more interesting inputs.

  • -o <and|or> (default: and)

    Specify the operator to be used to combine the two decision diagrams.

./build/src/${LIB}_apply_${KIND} -f benchmarks/apply/x0.bdd -f benchmarks/apply/x1.bdd -o and

CNF Solver

This benchmark loads a DIMACS CNF file, constructs its clauses and conjoins them. The benchmark uses the variable order specified in the CNF file and interprets the clause list as an approximately balanced tree, e.g. (c0 c1) (c2 (c3 c4)). It makes sense to preprocess raw CNF files using external tools and infer good variable and clause orders.

./build/src/${LIB}_cnf_${KIND} -f benchmarks/cnf/sample.cnf

Game Of Life

Solves the following problem:

Given N1 and N2, how many Garden of Edens exist of size N1xN2 in Conway's Game of Life?

The benchmark can be configured with the following options:

  • -n <int>

    The size of the sub-game. Use twice for non-quadratic grids.

  • -s <...>

    Restrict the search to symmetrical Garden of Edens:

    • none: Search through all solutions (default), i.e., no symmetries are introduced.

    • mirror/mirror-vertical: Solutions that are reflected vertically.

    • mirror-quadrant/mirror-quad: Solutions that are reflected both horizontally and vertically.

    • mirror-diagonal/mirror-diag: Solutions that are reflected across one diagonal (requires a square grid).

    • mirror-double_diagonal/mirror-double_diag: Solutions that are reflected across both diagonals (requires a square grid).

    • rotate/rotate-90: Solutions that are rotated by 90 degrees (requires a square grid).

    • rotate-180: Solutions that are rotated by 180 degrees.

All symmetries use a variable order where the pre/post variables are zipped and and follow a row-major ordering.

./build/src/${LIB}_game-of-life_${KIND} -n 5 -n 4 -o rotate-180

Hamiltonian Cycle

Solves the following problem:

Given N1 and N2, how many hamiltonian cycles exist on a Grid Graph size N1xN2?

The benchmark can be configured with the following options:

  • -n <int>

    The size of the grid; use twice for non-quadratic grids.

  • -e <...> (default: time)

    Pick the encoding/algorithm to solve the problem with:

    • time/t: Based on [Bryant2021], all O(N4) states are represented as individual variables, i.e., each variable represents the position and time. A transition relation then encodes the legal moves between two time steps. By intersecting moves at all time steps we obtain all paths. On-top of this, hamiltonian constraints are added and finally the size of the set of cycles is obtained.

    • binary: Based on [Marijn2021] with multiple tweaks by Randal E. Bryant to adapt it to decision diagrams. Each cell's choice of move, i.e., each edge, is represented by a binary number with log2(4) = 2 variables. Yet, this does not enforce the choice of edges correspond to a Hamiltonian Cycle. Hence, we further add log2(N2)-bit binary counter gadgets. These encode if u->v then v=u+1 % N2.

The time encoding are designed with ZDDs in mind whereas the binary encoding is designed for BDDs. That is, using the time encoding with BDDs does not give you great, i.e., small and fast, results.

./build/src/${LIB}_hamiltonian_${KIND} -n 6 -n 5

McNet

Important

ZDDs are not supported for this benchmark (yet)!

This simple Model Checker for Nets (pronounced "Mac Net", "magnet" or maybe "Monet"?) provides algorithms for the exploration of various transition system formats.

  • -f <path>

    Path to a file with a Petri Net (.pnml) or a Boolean Network (.aeon, .bnet, .sbml). You can find multiple inputs in the benchmarks/mcnet folder together with links to larger and more interesting inputs.

  • -a <...>

    The algorithm(s) to run. All algorithms depend on having computed the reachable states.

    • reachable/reachability: Compute the set of reachable states.

    • deadlocks: Compute the set of reachable deadlock states.

    • scc: Compute each Strongly Connected Component using the Chain algorithm from [Larsen2023]

  • -o <...> (default: input)

    Each BDD variable represents a location in the net. Hence, the variable ordering can have a major impact on the diagrams' size.

    • cuthill-mckee: Use the Cuthill-McKee order derived from the incidence graph, i.e. where variables are connected if they occur together in the same transition.

    • input: Use the order in which the locations are declared in the file.

    • random: A randomized ordering of variables.

    • sloan: Use Sloan's ordering derived from the incidence graph, where variables are connected if they occur together in the same transition.

  • -s <...>

    Merges the transition relation together into one with the given semantics. If not set, then the model is explored with asynchronous semantics and a disjoint relation.

    • asynchronous: Explore the model instead with asynchronous update semantics and a single joined relation.

    • synchronous: Explore the model instead with synchronous update semantics.

./build/src/${LIB}_mcnet_${KIND} -f benchmarks/mcnet/split.pnml

Picotrav

This benchmark is a small recreation of the Nanotrav example provided with the CUDD library [Somenzi2015]. Given a hierarchical circuit in (a subset of the) Berkeley Logic Interchange Format (BLIF) a BDD is created for every net; dereferencing BDDs for intermediate nets after they have been used for the last time. If two .blif files are given, then BDDs for both are constructed and every output net is compared for equality.

The benchmark can be configured with the following options:

  • -f <path>

    Path to a .blif file. You can find multiple inputs in the benchmarks/picotrav folder together with links to larger and more interesting inputs.

    If used twice, the BDDs for both circuits' output gates are constructed and checked for logical equality.

  • -m order|name (default: order)

    In case two circuits are given as inputs to verify their equivalence, match the inputs and outputs of these circuits by the order in which they occur in the input files or by their names.

  • -o <...> (default: input)

    BDD variables represent the value of inputs. Hence, a good variable ordering is important for a high performance. To this end, one can use various variable orderings derived from the given net.

    • input: Use the order in which they are declared in the input .blif file.

    • zip: Assuming that the input variable order is a[0], a[1], …, a[n-1], b[0], b[1], …, b[n-1] in the input .blif file, use the order a[0], b[0], a[1], b[1], …, a[n-1], b[n-1].

    • df/depth-first: Variables are ordered based on a depth-first traversal where non-input gates are recursed to first; thereby favouring deeper nodes.

    • level: Variables are ordered based on the deepest reference by another net. Ties are broken based on the declaration order in the input (input).

    • level_df: Similar to level but ties are broken based on the ordering in df rather than input.

    • fanin: Similar to depth-first, but before recursing, all child nodes are sorted by their depth. Recursive calls are done from the deepest to the most shallow node in order.

    • random: A randomized ordering of variables.

./build/src/${LIB}_picotrav_${KIND} -f benchmarks/picotrav/not_a.blif -f benchmarks/picotrav/not_b.blif -o level_df

QBF Solver

Important

ZDDs are not supported for this benchmark (yet)!

This benchmark is a small recreation of Jaco van de Pol's Qubi project. Given a Quantified Boolean Formula (QBF) in the qcir format, the decision diagram representing each gate is computed bottom-up. The outermost quantifier in the prenex is not resolved with BDD operations. Instead, if the decision diagram has not already collapsed to a terminal, a witness or a counter-example is obtained from the diagram.

  • -f <path>

    Path to a .qcir file. You can find multiple inputs in the benchmarks/qbf folder together with links to larger and more interesting inputs.

  • -o <...> (default: input)

    Each BDD variable corresponds to an input variables, i.e., a literal, of the qcir circuit. To keep the decision diagrams small, one can choose from using different variable orders; each of these are derived from the given circuit during initialisation.

    • input: Use the order in which variables are introduced in the .qcir file.

    • df/depth-first: Order variables based on their first occurence in a depth-first traversal of the circuit.

    • df_rtl/depth-first_rtl: Same as df but the depth-first traversal is right-to-left for each gate in the circuit.

    • level/level_df: Order variables first based on their deepest reference by another gate. Ties are broken based on the depth-first (df) order.

    If the input ordering is used, then the gates of the circuit are also resolved in the order they were declared. Otherwise, for df and level, gates are resolved in a bottom-up order based on their depth within the circuit.

./build/src/${LIB}_qbf_${KIND} -f benchmarks/qbf/example_a.qcir -o df

Queens

Solves the following problem:

Given N, in how many ways can N queens be placed on an N x N chess board without threatening eachother?

Our implementation of these benchmarks are based on the description of [Kunkle2010]. Row by row, we construct an BDD that represents whether the row is in a legal state: is at least one queen placed on each row and is it also in no conflicts with any other? On the accumulated BDD we then count the number of satisfying assignments.

The benchmark can be configured with the following options:

  • -n <int>

    The size of the chess board.

./build/src/${LIB}_queens_${KIND} -n 8

RelProd

Important

ZDDs are not supported for this benchmark (yet)!

Building on-top of the Apply benchmark, this benchmark loads a relation and a set of states stored in a binary format (as they are serialized by the LibBDD library) and then combines them with a Relational Product operation in either direction.

The benchmark can be configured with the following options:

  • -o <next|prev> (default: next)

    Specify whether the transition relation should be traversed forwards (next) or backwards (prev).

  • -r <path>

    Path to a .bdd / .zdd file that contains the relation. It is also assumed, that this relation includes the frame rule.

  • -s <path>

    Path to a .bdd / .zdd file that contains the set of states.

./build/src/${LIB}_relprod_${KIND} -r benchmarks/relprod/self-loop/relation.bdd -s benchmarks/relprod/self-loop/states_all.bdd -o next

Tic-Tac-Toe

Solves the following problem:

Given N, in how many ways can Player 1 place N crosses in a 3D 4x4x4 cube and have a tie, when Player 2 places noughts in all remaining positions?

This benchmark stems from [Kunkle2010]. Here we keep an accumulated BDD on which we add one of the 76 constraints of at least one cross and one nought after the other. We add these constraints in a different order than [Kunkle2010], which does result in an up to 100 times smaller largest intermediate result.

The interesting thing about this benchmark is, that even though the BDDs grow near-exponentially, the initial BDD size grows polynomially with N, it always uses 64 variables number and 76 Apply operations.

  • -n <int>

    The number of crosses are placed in the 64 positions.

./build/src/${LIB}_tic-tac-toe_${KIND} -n 20

Performance Regression Testing

This collection of benchmarks is not only a good way to compare implementations of BDD packages. Assuming there are no breaking changes in a pull request, this also provides a way to test for performance regression.

To this end, regression.py provides an interactive python program that fully automates downloading inputs and running and analysing the benchmark timings of two branches. For a non-interactive context, e.g., continuous integration, all arguments can be parsed through stdin. For example, the following goes through all the prompts for using the 8-Queens problem to test Adiar with 128 MiB origin/main (against itself) with no verbose build or runtime output and with at least 3 and at most 10 samples.

python regression.py <<< "queens
8
adiar
128
origin
main
origin
main
no
no
3
10
"

Between min and max number of samples are collected, until both the baseline and the under test branches have a standard deviation below 5%. For smaller instances, samples are collected for at least 30 minutes whereas for larger instances, the last sampling may start after 90 minutes.

The python script exits with a non-zero code, if there is a statistically relevant slowdown. A short and concise report is placed in regression_{package}.out which can be posted as a comment on the pull request.
