Embry-Riddle[1]

Accelerating the Post‐Processing of Large Scale Unsteady CFD Applications via In Situ Data Reduction and Extracts
Dr. Earl P.N. Duque
Manager of Applied Research, Intelligent Light

Tuesday, April 14th, 2015
1245‐1400 hrs
Lehman Building Room 272

ABSTRACT:
Writing, storing, moving and post‐processing vast unsteady datasets can interfere with an engineer’s interpretation and reporting of results. This seminar will present ongoing research to develop new methods designed to extract and reduce large unsteady CFD derived volumetric data. In‐Situ data extraction whereby sub‐setting and segmenting the volume data using data extraction and analysis libraries directly integrated within the solver codes themselves is the first step. To further reduce the amount of unsteady CFD extract data written to disk, methods such as Proper Orthogonal Decomposition may be used to reconstructed the solution data within a given error band. This seminar will present preliminary research and how the CFD could use these techniques to analyze their large‐scale CFD solutions.

In-Situ Post-Processing Discussion at NASA Applied Modeling & Simulation

by Roger Rintala | January 14, 2015 4:43 pm

NASA [1]Applied Modeling & Simulation (AMS) Seminar Series[2] to host Intelligent Light speaker on Friday, January 16, 2015. (Series info[3])

 

In Situ Post-Processing with VisIt, Libsim, and FieldView

Speaker: Brad Whitlock, Applied Research Group, Intelligent Light

The widening gap between compute performance and the ability to store computation results dictates that data analysis and visualization be performed in situ during simulation runs. Saving analysis results and data extracts offers tremendous opportunities for reduction in storage costs while also permitting greater access to data in the temporal domain. Libsim is a library which enables a fully-featured visualization tool, VisIt, to request data as needed from the simulation and apply visualization algorithms in situ with minimal modification to the application code. In this talk, the motivation for in situ processing is presented and the steps to instrument a simulation using Libsim are covered. Instrumenting simulation codes with Libsim opens up new possibilities for higher productivity workflows such as automatic creation of FieldView extract databases (XDBs) which can be visualized efficiently using the post-processing tool FieldView.

IL Meets Aerospace Leaders at AIAA SciTech 15

by Roger Rintala | January 5, 2015 4:44 pm

AIAA SciTech 2015 logo[1]Our most important Aerospace Meeting of the year is underway.  During SciTech, we are meeting with our users, demonstrating new product capabilities, and bringing IL and guest speakers[2] to our booth for conference attendees.

SciTech_Demos[3]

Specially invited guest speakers will share some of their work in a personal, small audience setting in our booth.  Intelligent Light staff will provide detailed information about the latest from our company.  All speakers will be available for personal discussions.

 

For our Japanese speaking customers we’ll have a special presentation session in Japanese.  Also, our new Asia Pacific Technical Office lead will be at the booth to present and answer questions.

Revolutionizing Innovation with On-Demand HPC

by Roger Rintala | January 5, 2015 8:00 am

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.[1]

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[2] and the  HPC User Forum[3] 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

by Roger Rintala | November 12, 2014 9:00 pm

SC14-Logosm[1]Intelligent 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[2] for use in production engineering environments.

 

visitlogo[3]VisIt 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[4] brings many additions and fixes developed by Intelligent Light and the ability to export XDB files[5] 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:
