ScienceNode: Wind Farm CFD by University of Wyoming and Intelligent Light

In Situ processing enables full wind farm simulation by reducing file size from 234TB to under 1TB

Researchers at the University of Wyoming (UW) and Intelligent Light are working hard to improve the efficiency of wind energy. One aspect they're currently investigating is the use of computational fluid dynamics (CFD) to simulate, predict, and improve the performance of wind farms.

CFD uses supercomputers to model the behavior of fluids such as air or water over moving surfaces. In this instance, UW professor of mechanical engineering Dimitri Mavriplis and Earl Duque at Intelligent Light turned to CFD to study how wind currents transform after coming into contact with a moving turbine's blades in the context of a complete wind farm.

Using the Cheyenne supercomputer at the National Center for Atmospheric Research (NCAR)-Wyoming Supercomputer Alliance, Duque and UW researchers Mavriplis, Michael Brazell and Andrew Kirby were able to model wind farms in unique ways. 

What really makes their research unique is the use of in-situ processing. Unlike traditional visualizations produced from stored data, in-situ processing means that visualizations and analysis can be created as a simulation takes place, without writing to disk.

In-situ processing eliminates file transfer bottlenecks, allows increased fidelity, and faster turnaround. 

"In-situ has helped reduce the amount of 3D data that we need to store. Just the restart files take 10 TB on a 12-hour run. Automation has gone way up; we have scripts that go straight from simulation to animation. Also, in-situ has helped with debugging—I don't need to pull down 3D data, and I can just use slices, save those to a FieldView XDB file, and then view that on my local machine."

    ISAV2017: In Situ Infrastructures for Enabling Extreme-Scale Analysis and Visualization

    SC17 Workshop
    Sunday, Nov. 12th, 9:00-5:30 pm room 605

    The considerable interest in the HPC community regarding in situ analysis and visualization is driven by the desire to save I/O costs and time, increase accuracy with fine sampling of transient analysis and full utilization of HPC resources. As a member of the ISAV Program Committee, Intelligent Light will bring real world experience from our work on ultra scale simulations.

    Intelligent Light is a co-organizer with a team including four US National Laboratories. We also participate on the program committee and have a role in reviewing submissions for this full day workshop.

    Tutorial: In Situ Analysis and Visualization with SENSEI
    Presenters: Bethel, Bauer, Whitlock, Wolf, Loring, Rizzi
    Monday, Nov.13th, 8:30 am - 12:00 pm room 355-D

    The SENSEI community in situ data interface is an API that promotes code portability and reusability. From the simulation view, a developer can instrument their code with the SENSEI API and then make use of any number of in situ infrastructures. From the methods view, a developer can write an in situ method using the SENSEI API, then expect it to run in any number of in situ infrastructures. Attendees will learn the fundamentals of in situ data analysis and visualization leveraging this generic interface.
