Deployments

Over the past decade, Velo has been deployed operationally by several U.S. government agencies and as part of multiple PNNL Laboratory Directed Research and Development projects.

Ongoing Deployments

U.S. Department of Energy

  • Office of Environmental Management (EM), Advanced Simulation Capability for Environmental Management (ASCEM). ASCEM has developed a Velo-based reusable software framework that facilitates rapid generation of science-based reactive flow and transport simulation capabilities and supporting modeling toolsets within a high-performance computing framework to address DOE-EM’s waste storage and environmental cleanup challenges. https://akuna.labworks.org/
  • Subsurface Biogeochemical Research (SBR), PNNL Science Focus Area (SFA) Project: Hydro-Biogeochemical Process Dynamics in the Groundwater-Surface Water Interaction Zone. The SBR-SFA team is actively using Velo to manage, analyze, and publish heterogeneous, multiscale data. http://sbrsfa.pnnl.gov/
  • Office of Energy Efficiency and Renewable Energy (EERE), Geothermal Technologies Office (GTO). A web-based Velo application is being employed by an international user base to support the GTO Code Comparison Study for collaboration, data management, benchmark and challenge problem descriptions, and results comparison. https://gto.velo.pnnl.gov
  • Office of Fossil Energy (FE), Southwest Regional Partnership on Carbon Sequestration (SWP). A web-based Velo application is being used for collaboration and data management to support the SWP Development Phase Enhanced Oil Recovery (EOR) project being conducted in the Farnsworth Unit in northern Texas. https://swp.velo.pnnl.gov/
  • Office of Biological and Environmental Research (BER), Accelerated Climate Model for Energy (ACME). The ACME project is using Velo’s simulation management and ProvEn provenance services to uniformly execute climate simulations with detailed provenance capture from their web portal. http://climatemodeling.science.energy.gov/projects/accelerated-climate-modeling-energy
  • Office of Fossil Energy (FE), Subsurface Technology and Engineering Research, Development, and Demonstration (SubTER) Big Data Analytics for Induced Seismicity. SubTER is extending Velo’s simulation management services to uniformly execute high-performance computing, Hadoop Map/Reduce and Spark, and ArcGIS Server jobs from the National Energy Technology Laboratory’s Energy Data eXchange (EDX) web portal. https://edx.netl.doe.gov/

Environmental Protection Agency

  • Geologic Sequestration Data Tool (GSDT). GSDT is a web-based Velo application for Class VI Underground Injection Control (UIC) permit applications employed both by well owners and operators to submit various components of a permit application, as well as by EPA regional and headquarters staff to afford a collaborative applications review process. The EPA GSDT is subsequently used for monitoring injection well operations. https://epa.velo.pnnl.gov/

Past Projects

PNNL Laboratory Directed Research and Development

  • Fused Analytic Desktop Environment (FADE). FADE provided analysts in information-driven fields with a range of information analysis technologies that are capable of handling ad hoc data sources and integrated into a single, easy-to-use system. http://availabletechnologies.pnnl.gov/technology.asp?id=285, http://www.innovation-america.org/digging-deeper-data
  • PNNL Chemical Imaging Initiative, Pooled Resources for Electron Microscopy Informatics Education and Research (PREMIER) Network. PREMIER has provided a Velo-based repository for sharing microscopy resources and capabilities across a heterogeneous community that spans numerous campuses and sites. http://www.premiernetwork.org/
  • Platform for Regional Integrated Modeling and Analysis (PRIMA). The PRIMA initiative’s goal was to develop a framework for the critical analyses of trade-offs and consequences of decision- and policy-making for integrated human and environmental systems. This was achieved by coupling various regional climate, energy, hydrological, and land-use models to create a Velo supported high-resolution modeling tool. http://prima.pnnl.gov/
  • PNNL Chemical Imaging Initiative, Rapid Experimental Analysis (REXAN). REXAN offered a collaborative environment for managing imaging experiments, image processing pipelines, provenance, and visualization tools, as well as prototyped dynamic semantic visualization pipelines and a Secure Global Desktop for remote visualization.

U.S. Department of Homeland Security

  • Domestic Nuclear Detection Office (DNDO), ModCat Radiation Model Catalog. The DNDO funded the Model Catalog, which was a web-based Velo repository for sharing radiation transport models.
  • Biodefense Knowledge Center. This center was a national hub for technical analysis of biodefense topics. Velo (formerly CAT) began its life supporting of this project, focusing on key collaboration and tool integration components.
  • Gang Taskforce, Seattle Law Enforcement (with King County Sheriff’s Office and Seattle Police Department). Project uniquely mixed relational-file-based database of gangs, gang members, and gang activity in the Seattle area. The effort was integrated with PNNL’s IN-SPIRE™ Visual Document Analysis (http://in-spire.pnnl.gov/) for data analysis.

U.S. Department of Energy

  • Office of Biological and Environmental Research (BER), Community Land Model (CLM). The simulation tool framework developed under ASCEM was extended to provide a Velo-based application for managing the Community Earth System Model’s CLM.
  • Carbon Capture Simulation Initiative (CCSI), Risk Estimation. A web-based Velo application provided an integrated probabilistic risk assessment methodological framework and the decision-support tool suite for implementing systematic comparisons of competing carbon capture technologies. The risk tools helped to operationalize CCSI’s technology readiness level assessment by identifying specific scientific and engineering targets required by each readiness level and applying probabilistic estimation techniques to calculate the likelihood of graded and nonlinear advancement in technology maturity. https://www.pnnl.gov/main/publications/external/technical_reports/PNNL-21785.pdf
  • Carbon Capture Simulation Initiative (CCSI), Reduced Order Model Builder (REVEAL). A Velo-based desktop application provided the collaborative modeling repository to support team development of Reduced Order Models (ROMs) that provide a computationally efficient and accurate representation of high-fidelity, computationally expensive simulations.
  • Office of Fossil Energy (FE), FutureGen2. A web-based Velo application was used for collaboration and data management in support of the FutureGen 2.0 geologic sequestration pilot project.
  • Sim-SEQ. A web-based Velo application was used for collaboration and data management in support of the DOE’s Sim-SEQ project, managed by Lawrence Berkeley National Laboratory. The project’s objective was to understand model uncertainties in geologic carbon sequestration. http://esd.lbl.gov/projects/sim-seq/
  • Office of Biological and Environmental Research (BER), Foundational Scientific Focus Area (FSFA): Principles of Microbial Design. The Microbes SFA team used Velo to collaborate and manage their heterogeneous experiment/project data. https://www.pnnl.gov/biology/programs/fsfa/
  • Small Business Innovation Research (SBIR), Nimble: A Data Management and Visualization Framework for Large-Scale Engineering and Science Validation, Verification, and Uncertainty Quantification Applications. This collaboration with Intelligent Light, Inc., extended the then-newly created Nimble framework to support Velo as the data management backend for mining simulation metadata.

Battelle Memorial Institute

  • Battelle Threat Anticipation Initiative, Hippogriff. This involved a Velo-based desktop client prototype for estimating potential event probabilities from ad hoc news streams, natural language processing, and semantic network analysis.
