Intelligent Light Makes the Benefits of High Performance Computing Accessible to CFD Users at All Levels

Legensky to Deliver Masterworks Presentation on HPC in Wind Energy at SC09 Conference

As the technology world turns its attention to the many facets of supercomputing at the SC09 conference in Portland this week, Intelligent Light, developer of the industry-leading computational fluid dynamics (CFD) post-processing FieldView™ software, is helping engineers, designers, and researchers reap the benefits of today's high performance computing (HPC) resources every day in real world applications.

Advances in HPC are significantly expanding the size of data that can be collected, allowing a dramatic increase in the realism and complexity of simulations. But in order for scientists, researchers, and engineers to get the answers they need from these massive datasets, the applications running on these super systems have to keep pace.

"Big data is just getting bigger," says Steve Legensky, Intelligent Light general manager. "Leveraging that information, being able to efficiently extract meaningful results, requires tools and processes that can manage complexity and ensure productivity. We want all CFD users, whether in small companies or large corporate engineering environments, to be able to harness the power of their available computing resources, break through bottlenecks, and interrogate any size dataset with FieldView. Its intuitive, user-friendly interface, speed, and power have made FieldView the choice of thousands."Architected to exploit multi-core and multi-processor computers operating as a single system or in HPC clusters, FieldView's "3 for Free" scaling allows users on two to four cores to easily take advantage of its parallel features. When running in parallel, FieldView 12.2 processes runs at least twice as fast on four processor cores, and up to five times faster on eight processor cores. The Japanese space agency JAXA, which regularly deals with multi-billion-node unsteady CFD cases, relies on FieldView to ensure productive, effective post-processing. JAXA recently reported that one dataset, a 1.3 billion node case, was fully read into FieldView in less than two minutes on a Fujitsu M9000 system.

The synergy between Intelligent Light's research efforts and its FieldView product line is evidenced by the company's development of a scalable solution for aero-acoustics and terascale data for its Rotorcraft Computational Aero-Acoustics Post-processing System (RCAAPS) program, sponsored by a NASA Langley SBIR Phase II contract. Intelligent Light is close to commercializing the results of this multi-year project, which brings together distributed computing systems, CFD solvers, and post-processing techniques in a wholly new approach.

"Aero-acoustic simulations are critical in rotorcraft, fixed wing aircraft, and turbomachinery, and are also being used to solve design challenges in wind energy, automotive design, and even consumer products," Legensky says. "When acoustics and CFD are coupled, the data demands are enormous. The RCAAPS work has the potential to revolutionize the way investigators in these fields explore large, unsteady simulations and how they manage these large datasets. And, as we deploy what we've learned and developed into future FieldView releases, those same benefits will accrue to CFD users across all industries."

Legensky will discuss the implications of HPC for the wind energy industry at SC09 with a Masterworks presentation, "HPC and the Challenge of Achieving a Twenty-fold Increase in Wind Energy," on Tuesday, November 17 at 10:30 a.m. Despite tremendous strides in wind power generation over the past two decades, wind farms today are underperforming on predicted cost of energy by an average of 10%, and operating expenses remain high. In order to meet a federal goal of wind power providing 20% of U.S. electricity needs by 2030, performance problems must be solved. Analysis and system-level optimization of the machines, wind farm location and configuration, coupled with accurate meso-microscale weather modeling will need to be developed and validated. This unsteady, turbulent, multi-scale modeling will only be possible through the use of large-scale HPC resources.

Other SC09 activities in which Intelligent Light is involved include the Posters track, with a report on the innovative research being done on the use of Graphics Processing Units (GPU) for computational tasks. In addition, Intelligent Light's Applied Research Group has been working with Northrop Grumman on a joint solution for integrating very large and smaller scale data in a smooth workflow that can provide the information required to enhance the consistent and cost-effective delivery of power in wind and solar facilities. This work will be featured in the Northrop Grumman exhibit booth.

Intelligent Light also has a stake in SC09's Student Cluster Competition, which challenges high-school and college students to run a workload of real-world applications on clusters of their own design in real time. Dr. Earl P.N. Duque, manager of Intelligent Light's Applied Research Group, is coaching the Arizona State University Cluster Devils team. A former member of an advanced computational research methods group for the National Aeronautics and Space Administration (NASA), Dr. Duque will draw on his expertise in these advanced areas of engineering and computing to guide the team.

Time Scale Visualizations in CFD Studies

 M.N.Godo, Ph.D. - FieldView Product Manager

Mixing processes are involved at some level in of nearly all chemical manufacturing processes and are fundamental to the successful operation of combustion-driven systems. Today, many CFD practitioners in the chemical process industry are able to use simulation to obtain detailed insight on the overall performance of their process equipment. However, it is still difficult to relate CFD data to the effective management and control of a particular process. In addition, the cost of production delays due to sudden, unexpected changes in product quality provide strong motivation to understand the impact and relevance of CFD studies that are focused on these areas.Related Information
