Cyberinfrastructure 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.

WRENCH Research Paper:

WRENCH is fully developed in C++. The code follows the C++14 standard, and thus older compilers tend to fail the compilation process. Therefore, we strongly recommend users to satisfy the following requirements:

• CMake - version 3.7 or higher

And, one of the following:

• g++ - version 6.3 or higher
• clang - version 3.8 or higher

• SimGrid - version 3.29
• PugiXML - version 1.8 or higher
• JSON for Modern C++ - version 3.9.0 or higher

• 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

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

cmake .
make
sudo make install

For enabling the use of Batsched:

cmake -DENABLE_BATSCHED=on .
make
sudo make install

To use a non-standard SimGrid installation path:

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

Bug Report / Feature Request: our preferred channel to report a bug or request a feature is via
WRENCH's Github Issues Track.

When citing WRENCH, please use the following paper. You should also actually read that paper, as it provides a recent and general overview on the framework.
