Cyberinfrastructure Simulation Workbench

WRENCH is an open-source library that provides high-level simulation abstractions that serve as building blocks for developing custom simulators of distributed computing systems, platforms, and applications.

Prerequisites

WRENCH is fully developed in C++. The code follows the C++17 standard, and thus older compilers tend to fail the compilation process. Therefore, we strongly recommend users to satisfy the following requirements:

• CMake - version 3.10 or higher

And, one of the following:

• g++ - version 7.5 or higher
• clang - version 9.0 or higher

Dependencies

Required Dependencies

• SimGrid - version 3.36
• SimGrid File System Module - version 0.2 or higher
• JSON for Modern C++ - version 3.11.0 or higher

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)
• Sphinx - version 4.5 or higher along with the following Python packages: pip3 install sphinx-rtd-theme breathe recommonmark (only required for generating documentation)
• Batsched - version 1.4 - useful for expanded batch-scheduled resource simulation capabilities
• Asio - necessary only for building wrench-daemon

Building From Source

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

mkdir build
cd build
cmake ..
make
sudo make install

For enabling the use of Batsched:

mkdir build
cd build
cmake -DENABLE_BATSCHED=on ..
make
sudo make install

To use a non-standard SimGrid installation path:

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