Intelligent Light is using SBIR grants to tap the
power of VisIt, a visualization program supported in
part by the Advanced Scientific Computing Research (ASCR) program in the Department of Energy (DOE) Office of Science.

 

Intelligent Light was selected as a trusted vendor who could provide the expertise and discipline to tailor tools to industrial workflows while commercializing and hardening the government developed code.  Intelligent Light is providing industrial grade software development, engineering service and customer support to end users.

 

The project enables Intelligent Light to hold down development cost and end-user investments by utilizing open source code developed by DOE.  Moreover, the project is helping Intelligent Light customers move to in-situ post-processing years earlier than if IL had developed all of the required technology from scratch.

 

Eric Brugger and other Lawrence Livermore National Laboratory scientists designed VisIt to visualize the mounds of simulation data DOE supercomputers generate. It’s built to scale well and it’s well suited for in situ processing.

 

“VisIt … is an open-source code, free to download and modify, as thousands of researchers have. With no licensing fees, merging VisIt into FieldView will hold
down costs for small- and medium-sized companies using it on HPC systems.”

Intelligent Light responded to a call by ASCR to harden and commercialize DOE-supported software for high performance computing applications, making the tools robust and accessible.  Working under a Phase II grant of nearly $1 million, Intelligent light is integrating VisIt into our FieldView HPC suite. The funding is from a U.S. Small Business
Innovation Research (SBIR) program, which provides capital for early research and development with commercial potential.

 

VisIt’s big-data capacity allows FieldView to handle a wider range of CFD visualization tasks. “But ‘if you want to turn it into a commercial product, you really have to spend the time to customize things to people’s workflows,’ Brugger says. ‘We’ve customized it to our workflows in the DOE community,’ but it doesn’t always fit other users workflows.”

 

ASCR recognized it needs help to move VisIt and other DOE-supported solutions for high-performance computing into commercial use. Through the SBIR program, it called
for small businesses able to take DOE codes and “shrink wrap” them into accessible tools.

 

The collaboration “shows DOE is taking its research and development and spawning new technology – which is one of our missions,” says Benjamin Grover, division leader for
Applications, Simulations, and Quality at Livermore.

 

With a Phase II grant of nearly $1 million, Intelligent Light is integrating VisIt into its FieldView HPC suite. Later this year, customers will be able to choose either the standard FieldView code or VisIt to visualize CFD data.

In-Situ Solver Integration using VisIt on the CREATE/AV Program

Helicopter and CarrierDoD’s CREATE/AV Kestrel team has demonstrated in-situ post-processing using DOE’s VisIt code with FieldView XDB export.

 

The US Air Force, Navy and Army make extensive use of large scale simulation in their research, design and procurement activities.  Over the past five years the DoD CREATE program has sought to develop and deploy new simulation technologies to assist in the procurement process.

 

As part of a ship-airwake program, engineers at the US Navy’s NAVAIR were tasked with simulating a helicopter flying towards a ship. This was a particularly challenging case due to the sheer size of the results files computed on an HPC resource.  Handling the files was an impediment to effective understanding.  With support from Intelligent Light’s VisIt Services, the team now has the ability to use their solver with open-source VisIt LibSim software module to perform in-situ post-processing and export XDB files.

 

Intelligent Light also provided support and enhanced VisIt to make it suitable for the complex mesh topologies common in Kestrel. The VisIt 2.8.0 release has many of these enhancements and the XDB export capability.

 

Intelligent Light VisIt Services delivered:

  • Rapid deployment of solutions to the problems identified by an expert VisIt developer
  • In-situ extraction via VisIt solves the problems with moving huge files in unsteady computation
  • XDB export in VisIt provides persistent extracts that can be further post-processed and visualized in FieldView
  • Services & support provided by a trusted vendor partner

Corvid uses IL VisIt Services to Customize & Improve VisIt

Crew ProtectionWhen working with large scale, unsteady, multiphysics simulations, Corvid Technologies makes extensive use of VisIt for post-processing and visualization of results.  VisIt helps them exploit HPC to present powerful, illuminating images and animations that share the knowledge gained through engineering simulation with clients.

 

Corvid Technologies turned to Intelligent Light when it became clear that some problems with their solver interface were inherent in the open-source VisIt code.  They needed results and to keep their staff working on other projects where their expertise was most valuable.

 

Intelligent Light’s VisIt Services team delivered:

  • Rapid deployment of solutions to the problems identified by an expert VisIt developer
  • Work performed concurrently with the revenue generating activity of the customer
  • Development that was contributed to the VisIt repository and resulted in an improved VisIt release
  • Services & support provided by a trusted vendor partner

Revolutionizing Innovation with On-Demand HPC

Many of our customers depend on HPC every day. Our direct involvement with customers working at the leading edge of HPC driven engineering is making people vastly more productive as they harness the power of HPC.

 

Successful example of cloud-based HPC for CFD use. Presented by Intelligent Light's Steve Legensky.

Successful examples of cloud-based HPC for CFD use. Data management and workflow engineering are important to the success of cloud-based CFD. Presented by Steve Legensky, General Manager and Founder, Intelligent Light.

Steve Legensky, our General Manager and Founder,  was recently invited to provide examples and successful strategies for cloud-based HPC.  The talks were delivered for the SC14 HPC Impact Showcase and the  HPC User Forum in Seattle.

 

Recognizing that CFD Solver Codes are often well suited to running in the cloud, CFD remains problematic for many because the results files can be very large and there can be many.  Effective analysis of these files essential to the CFD workflow and is the way users gain understanding.  Overcoming the constraints requires both data management and workflow engineering to deliver on the promise of on-demand HPC for CFD.

Leading Edge CFD Post-Processing in the Automotive Industry

Intelligent Light delivered a keynote presentation at the VINAS User Conference in Shinagawa, Japan.

 

How the Automotive Industry is Pushing the Limits of CFD Post-Processing with FieldView

CFD Engineers working in the automotive industry are being asked to simulate increasingly complex systems and phenomena, while having to deal with strong time and cost constraints. This is probably the reason why an increasing number of them are switching to FieldView, after trying other commercial or open source post-processors. In this presentation, we’ll review three automotive industrial examples, covering areas as different as engine thermal validation, external aero and internal combustion, which used the same technology (FieldView’s automation, high performance graphics and data extracts capabilities) but applied in different ways, thanks to the help of Intelligent Light’s Services Team. What these three companies had in common was the need to do more with the same hardware, whether that’s getting their post-processing results faster or being able to interact with large transient results in a way it had never been done before.
