What Is the SmartSim Zoo?#

Given that SmartSim is a community developed and maintained project, we have introduced a SmartSim Example Zoo that contains CrayLabs and user contributed examples of using SmartSim for various simulation and machine learning applications.

The Two Categories of the SmartSim Zoo#

  1. SmartSim Deployments (running SmartSim on various HPC Systems)

  • The source code for the repository serves the purpose of showing diverse

  • examples of how to get SmartSim running on different HPC Systems. If you are looking for working examples on a specific machine, then the source code in the SmartSim-Zoo repository is for you. The SmartSim development team strives to keep these examples updated with each release so that users will always have robust examples for their needs.

  1. SmartSim Applications (completed projects that use SmartSim)

  • The README for the repository describes some of the larger applications of

  • SmartSim. These examples fall under two categories: examples by paper and examples by simulation model. The examples by paper are based on existing research papers, and the examples by simulation models are integrations of SmartSim with existing simulation models.

How To Contribute#

We support, encourage, and welcome all contributions to the SmartSim Zoo repository. Instructions for contributing examples varies whether you are contributing a SmartSim deployment or a SmartSim application.

  1. Contributing SmartSim Deployment Examples

  • For contributing examples of SmartSim running on a HPC System, we ask that you include a description and all references to code and relevant previous implementations or open source code that the work is based on for the benefit of anyone who would like to try out your example.

  1. Contributing SmartSim Application Examples

  • For contributing examples of completed projects that use SmartSim, we ask that you follow the subsequent contribution template:

  1. Title of the project

  2. High-level description (the ‘elevator pitch’)

  3. SmartSim features used (e.g. online analysis, ensemble)

  4. Prerequisites: hardware and software

  5. Installation guide

  6. Quickstart

  7. Contact information

  8. Citation

Summary of SmartSim Application Examples#

  • DeepDriveMD: Based on the original DeepDriveMD work, extended to orchestrate complex workflows with coupled applications without using the filesystem for exchanging information.

  • TensorFlowFoam: Uses TensorFlow inside of OpenFOAM simulations using SmartSim. Displays SmartSim’s capability to evaluate a machine learning model from within a simulation with minimal external library code and minimal API calls.

  • ML-EKE: Runs an ensemble of simulations all using the SmartSim architecture to replace a parameterization (MEKE) within each global ocean simulation (MOM6).

  • LAMMPS + SmartSim: Implementation of a SMARTSIM dump style which uses the SmartRedis clients to stream data to an Orchestrator database created by SmartSim.
