THE WRENCH FRAMEWORK
Accurate, scalable, and reproducible simulations
WRENCH builds on the open-source SimGrid simulation framework for simulation accuracy (via its validated simulation models), scalability (low ratio of simulation time to simulated time, ability to run large simulations on a single computer with low compute, memory, and energy footprints), and expressivity (ability to simulate arbitrary platform, application, and execution scenarios). WRENCH provides high-level simulation abstractions on top of SimGrid to make it possible to implement simulators of complex scenarios with minimal development effort.
In a nutshell, WRENCH makes it possible to:
- Develop in-simulation implementations of runtime systems that execute application workloads on distributed hardware platforms managed by various software services commonly known as Cyberinfrastructure (CI) services; and
- Quickly, scalably, and accurately simulate, on a single computer, arbitrary application and platform scenarios for these runtime system implementation.
