SC14 – Invited IL Speakers Reflect the Changing HPC Landscape

Intelligent Light customers are often leaders in their industries.  We are proud of their accomplishments and our role in supporting their success.  In these two invited talks we will share brief stories of organizations who have made HPC a valuable resource for their businesses.

 

HPC Impact Showcase at SC14

Intelligent Light has been invited to participate in the 2nd Annual HPC Impact Showcase at SC14. The HPC Impact Showcase brings real world applications of HPC that make a difference in shaping our world. Intelligent Light General Manager and Founder, Steve Legensky, will share cases of leading organizations whose CFD business success is enabled by on-demand HPC. Presentations take place in the HPC Impact Showcase Theater on the exhibit floor.

Now! Generate FieldView XDB files directly from VisIt 2.8

VisIt users can now generate FieldView XDB files directly from VisIt scientific visualization software.  VisIt is highly scalable, open source visualization software developed by the US Department of Energy.  Intelligent Light is working under a DOE SBIR to provide a robust, hardened version of VisIt for engineering applications.  VisIt includes libsim which is a powerful tool that can be used in support of in-situ post-processing and visualization.  XDB files are generated rather than volume files for interrogation using FieldView.  XDBs help accelerate the CFD workflow also allowing researchers and engineers to ask more sophisticated questions by running more cases at higher fidelity.  These improved studies can increase accuracy and confidence and lead to new insights.

 

Researchers and engineers working on leadership class HPC systems use VisIt to work with the large datasets that result.  VisIt is built for these ultra-scalable systems, is free of licensing cost at any processor count, and is well suited for work where post-processing takes place as the simulations are run.  Writing out FieldView XDB files from Visit in an interactive session or from libsim in-situ provides persistent extract files which can then be used with FieldView software and archived in compact form for later use.  Leading users are already using the XDB export capability with in-situ post-processing.   FieldView XDB files are a fraction of the size of the original volume data yet retain full numerical fidelity.  When used with FieldView they enable both the interactive exploration of unsteady simulation data and the ready transfer of data.  FieldView is built for engineering productivity delivering powerful and accessible tools for CFD and supporting investments in high capacity, interactive and automated workflows.  This combination bridges the gap between expert users in research domains and engineering experts wishing to use HPC and in-situ post-processing in production environments.

 

Using XDBs to accelerate the VisIt workflow also allows researchers and engineers to ask more sophisticated questions by running more cases at higher fidelity.  These improved studies can increase accuracy and confidence and lead to new insights.

 

This is a significant milestone in the development and integration of VisIt with the engineering tools in FieldView that users depend on.  Intelligent Light’s development was performed largely by Brad Whitlock, a member of our Applied Research Group.  Brad is a long-time VisIt developer, formerly working for the Lawrence Livermore National Laboratory (LLNL).  Several advanced FieldView users are already using XDBs generated in VisIt.  This functionality is delivered in the VisIt 2.8 release for all users and will be supported through normal VisIt support channels.  FieldView users will also be supported through their existing Intelligent Light support programs.

Massive CFD Data Handled Quickly Without Compromise – Maximize Your CFD Investment

                This real world example uses analysis from the AIAA High Lift Drag Prediction Workshop simulations to show how XDB files enable wholly new levels of productivity for CFD.  The work was performed on a remotely located Cray XE6 system and reviewed locally.  The improvements in overall throughput can be even higher with VisIt running on the HPC systems and delivering the XDB files directly, without writing out large intermediate files.  The work discussed in the paper is was recognized by IDC with their HPC Innovation Excellence Award.

Interactive Exploration of High Fidelity ICE Simulations

Interactive Exploration of High Fidelity ICE Simulations

Learn how you can create and analyze ICE simulations with hundreds of time steps and hundreds of thousands of simulated particles.  Interactively explore your high fidelity data to improve understanding of your results.
Attend this webinar by Intelligent Light and Convergent Science to see how you can escape current limitations and achieve more from your CFD.

 

An innovative transient post-processing approach for ICE simulations

 

In the quest to improve simulation accuracy and fueled by the rise of HPC, simulations are being performed on ever finer meshes and with larger number of particles.  In the case of internal combustion engine CFD which requires very long transient runs in order to reach convergence, this has become problematic due to the huge amount of data and the time it takes to review it.
This presentation will describe, through an ICE case study simulated with CONVERGE, an innovative post-processing approach that allows interactive analysis of several hundreds of time steps, containing hundreds of thousands of simulated particles.

 

Combined with more traditional methods (transient animations, time history plots…), this interactive investigation technique will provide unprecedented insight to complex transient flows.

New AMD FirePro Graphics Qualified

AMD FirePro W5100We completed testing of the new AMD W5100 FirePro™ Graphics card at AMD’s request.  The new product includes 4GB of GDDR5 memory for great FieldView performance and we’ve added the product to our supported products database.

“Simply installing the AMD FirePro 5100 delivered an immediate two and a half times speedup over my existing engineering workstation graphics when when rendering turbulent structures around a real-world size Formula One CFD solution.  It was an easy productivity improvement.” – Yves-Marie Lefebvre, FieldView Product Chief

Still need more?  The larger W7100 doubles the memory and more than doubles the number of stream processors in a single slot card. For information on all the new FirePro Graphics options, visit amd.com.
