Ripples is a software framework to study the Influence Maximization problem. The problem of Influence Maximization was introduced in 2001 by Domingos and Richardson [DR01] and later formulated as an optimization problem under the framework of submodular functions by Kempe et al. [KTR03].

Given a graph G, a network diffusion model M, and positive integer k, the influence maximization problem is the problem of selecting a set of seeds S of cardinality k such that \mathop{\mathbb{E}}[I(S)] is maximized, where I(S) is the influence function.

Our goal with Ripples is to provide tools implementing fast and scalable state-of-the-art approximation algorithms to solve the influence maximization problem.

Quickstart with Conan

First of all we need to set up the Python environment needed.

$ pip install --user pipenv
$ pipenv --three
$ pipenv install
$ pipenv shell

Then we need to install dependencies:

$ conan create conan/waf-generator user/stable
$ conan create conan/trng user/stable
$ conan install .

Now we are ready to configure and build ripples:

$ ./waf configure --enable-mpi build
# or without MPI support
$ ./waf configure build

In the case you are a Mac OS user, you will need to install the LLVM toolchain through brew that comes with OpenMP support. Compiling Ripples than is as simple as:

$ ./waf configure --openmp-root=/usr/local/opt/llvm --enable-mpi build
# or without MPI support
$ ./waf configure --openmp-root=/usr/local/opt/llvm build

Quickstart with Docker

$ git clone <url-to-github>
$ cd ripples
$ docker-compose -f docker/docker-compose.yml pull head worker
$ docker-compose -f docker/docker-compose.yml up -d --scale worker=2
$ docker exec -u mpi -it docker_head_1 /bin/bash
$ cd $HOME/ripples
$ ./waf configure --enable-mpi build

To run the parallel IMM tool:

$ build/tools/imm  \
     -i test-data/karate.tsv \
     -p \
     -e 0.05 \
     -k 3 \
     -d IC \
     -o output.json

To run the MPI+OpenMP IMM tool on the docker cluster:

$  mpiexec --hosts=docker_worker_1,docker_worker_2 -np 2 build/tools/mpi-imm \
     -i test-data/karate.tsv \
     -e 0.05 \
     -k 3 \
     -d IC \
     -o output.json

Build Instructions

This project uses WAF as its build system. Building Ripples is a two-step process: configure the project and build the tools. Before attempting to build, be sure to have the following dependencies installed:

  • A compiler with C++14 support and OpenMP support.
  • Spdlog
  • JSON
  • TRNG4
  • An MPI library (optional)

The configure step can be invoked with:

$ ./waf configure

or optionally to enable the MPI implementations:

$ ./waf configure --enable-mpi

The build system offers options that can be used to help the configuration step locate dependencies (e.g., they are installed in unconventional paths). A complete list of the options can be obtained with:

$ ./waf configure --help

After the configuration step succeeds, the build step can be executed by running:

$ ./waf build

For more detailed instruction, please read :ref:`build:Step By Step Build Instructions`.

The tools compiled can be found under build/tools/. A complete set of command line options can be obtained through:

$ ./build/tools/<tool_name> --help
