    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.

    Visions of Exascale CFD: ASME Fluids Engineering Division Summer Meeting

    IL Founder & General Manager, Steve Legensky, will speak at the ASME Fluids Engineering Division Summer Meeting​ at the Hilton Waikoloa Village, Waikoloa, Hawaii

    Steve M. Legensky, Founder and General Manager, Intelligent Light

    Visions of Exascale CFD

    Over the past thirty years, computational simulation of fluid dynamics has made huge strides in meshing of complex geometries, computational efficiency and most importantly, greater fidelity in physics models.Current trends include greater adoption of unsteady methods via LES, higher order methods and alternatives to classical CFD such as Lattice Boltzmann methods.However, the majority of engineering applications remain constrained by computational and storage resources as well as schedule and time pressure.The Department of Energy's Exascale Computing Project (ECP) offers the capacity for scale, fidelity and perhaps most interesting, non-deterministic engineering (NDE) in which variations in boundary conditions, discretization and models can more realistically predict the behavior of complex aerodynamic, propulsion or power generation systems.

    Intelligent Light is participating in research activities aimed at managing the massive data flows resulting from ensembles of unsteady CFD calculations and implementing tools to support engineering use of uncertainty quantification techniques.Through the lens of post-processing and data analysis, we have gained a unique perspective on research and engineering use of CFD from the late 1980's through today.The talk will touch on this history but have a primary focus on state-of-the-art petascale CFD in aerospace, combustion and wind energy and survey the challenges that ECP is intended to address.

    Workshop: Extract-based and In Situ Methods for HPC Enabled CFD

    To be held August 3, 2017, in conjunction with the ASME Fluids Engineering Division Summer Meeting​ at the Hilton Waikoloa Village, Waikoloa, Hawaii

    Workshop Objectives

    This workshop will assess the state-of-the-art in CFD Visualization and Post-Processing in High Performance Computing (HPC) environments. Specifically the issues of data transfer from remote HPC resources, a comparison of remote graphics vs. extract methods, and the trend toward in situ methods. Real world examples of industrial CFD workflows will be presented that offer a path to greater fidelity and faster throughput enabling an increased use of unsteady simulation.

    Making Collaborative CFD Fly

    "This method of aggregating data and standardizing the interrogation of the data, especially large scale, full 3D multiphyisics data is very, very necessary and very, very useful. This partnership is exciting and we are exploring the boundaries of what we can achieve with this."

    Nathan Hariharan
    Chair, AIAA Helicopter Hover Prediction Workshop

    The world's helicopter community came together to study the complex physics of rotorcraft in hover using CFD. They needed a HPC collaboration hub that minimized researchers' efforts to collaborate in full 3D. We made it work for the AIAA Hover Prediction Workshop and we can make it work for you.

    Join Dr. Nathan Hariharan, Chair, AIAA Helicopter Hover Prediction Workshop, Dr. Earl Duque, Manager of Applied Research at Intelligent Light, and Michael Senizaiz, ‎Chief Technology Officer at R Systems, as they explore how work done to support the Hover Prediction Workshop is yielding valuable lessons for any organization looking to streamline its CFD workflow.

    Learn how Intelligent Light and R Systems provide the CFD expertise and on-demand HPC capability to make high-performance CFD workflow a reality:

    • Enable data sharing among many disparate members of the organization: CFD Engineers, Designers, Managers and Customers
    • Compare many different cases, even those with different meshes or from different solvers, etc.
    • Derive higher order features, like vortex path, automatically for comparison
    • Standardize the workflow so that input from many groups can be compared side by side, both visually and numerically
    • Utilize on-demand HPC resources to run automated post-processing workflows across all the datasets producing standardized outputs and enabling collaboration

    A live Q & A with the speakers will follow the presentation.

    When: Tuesday, May 9, 2017, 2:00 PM Eastern
