Simulation Building Blocks

Prototype implementations of cyberinfrastructure (CI) components and underlying algorithms

Simulation Accuracy

Captures the behavior of a real-world system with as little bias as possible via validated simulation models


Ability to run large simulations quickly on a single computer with low compute, memory, and energy footprints

Reproducible Results

Reproduction or repetition of published results by a party working independently using the same/different simulation models


eduWRENCH provides a set of simulation-driven, self-contained, modules for teaching parallel and distributed computing. These modules span a range of proficiency levels, from college freshmen to graduate students, and for assessing the pedagogic effectiveness of simulation-drive pedagogy

What is WRENCH?

WRENCH architecture

WRENCH enables novel avenues for scientific workflow use, research, development, and education in the context of large-scale scientific computations and data analyses. WRENCH is an open-source library for developing simulators. WRENCH exposes several high-level simulation abstractions to provide high-level building blocks for developing custom simulators.

WRENCH provides a software framework that makes it possible to simulate large-scale hypothetical scenarios quickly and accurately on a single computer, obviating the need for expensive and time-consuming trial and error experiments.

WRENCH enables scientists to make quick and informed choices when executing their workflows, software developers to implement more efficient software infrastructures to support workflows, and researchers to develop novel efficient algorithms to be embedded within these software infrastructures.
