v2.0
WRENCH is a simulation framework for building simulators of Cyberinfrastructure platforms, systems, and applications. WRENCH implements high-level simulation abstractions on top of the SimGrid simulation framework, so as to make it possible to build simulators that are accurate, that can run scalably on a single computer, and that can be implemented with minimal software development effort.
This is a major release, which includes:
- Created a more general Developer API, called the action API, that makes it possible
to simulate application workloads that are not necessarily workflow applications. Examples
are provided in theexamples/action_apidirectory. - Minor changes to the workflow API (which is now implemented internally on top of the action API).
- Removed support for the obsolete DAX XML workflow description format, which removes an external software dependency.
- Added support for the WfCommons JSON workflow description format.
- Many additional API functionality, typically as requested by users.
- Scalability improvements both in terms of simulation time and simulation memory footprint.
- New and improved documentation.
Note: WRENCH 2.0 requires SimGrid 3.31.
