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.

VisIt Presentations and Demonstrations at SC14

SC14-LogosmIntelligent Light looks forward to SC14, the premier gathering of HPC users, providers, and developers.  We return to the conference in continued support of the VisIt community.  VisIt is massively scalable, open source visualization software developed by the Department of Energy for which Intelligent Light is working to harden and extend for use in production engineering environments.

 

visitlogoVisIt is already being used to help harness the power of leadership class HPC and some of our leading customers have embraced it as a powerful tool for in-situ post-processing, an essential emerging capability for high throughput CFD.  VisIt 2.8 brings many additions and fixes developed by Intelligent Light and the ability to export XDB files is the first step in our path for bringing VisIt into the  FieldView world, where thousands of CFD users do important engineering and research work every day.

 

During SC14 presentations in our booth #3617 include:

SC14 Tutorial: Effective HPC Visualization and Data Analysis using VisIt

Effective HPC Visualization and Data Analysis using VisIt

Visualization and data analysis are an essential component of the scientific discovery process. Scientists and businesses running HPC simulations leverage visualization and analysis tools for data exploration, quantitative analysis, visual debugging, and communication of results. This half-day tutorial will provide attendees with a practical introduction to mesh based HPC visualization and analysis using VisIt, an open source parallel scientific visualization and data analysis platform. We will provide a foundation in basic HPC visualization practices and couple this with hands-on experience creating visualizations and analyzing data. This tutorial includes:
