Workflow Management System Simulation Workbench

WRENCH is an open-source library for developing workflow simulators. WRENCH exposes several high-level simulation abstractions to provide the building blocks for developing custom simulators.

More information and Documentation: WRENCH Project Website

WRENCH Research Paper:


WRENCH is fully developed in C++. The code follows the C++11 standard, and thus older compilers tend to fail the compilation process. Therefore, we strongly recommend users to satisfy the following requirements:

  • CMake - version 3.5 or higher

And, one of the following:

  • g++ - version 5.0 or higher
  • clang - version 3.6 or higher


Required Dependencies

Optional Dependencies

  • Google Test - version 1.8 or higher (only required for running test cases)
  • Doxygen - version 1.8 or higher (only required for generating documentation)
  • Batsched - only needed for batch-scheduled resource simulation

Building From Source

If all dependencies are installed, compiling and installing WRENCH is as simple as running:

cmake .
sudo make install

For enabling the use of Batsched:

sudo make install

To use a non-standard SimGrid installation path:

cmake -DSIMGRID_INSTALL_PATH=/my/simgrid/path/ .
sudo make install
