Intelligent Light and FieldView

28th International Conference on Parallel CFD held in Kobe Japan, May 9-12, 2016

28th International Conference on Parallel Computational Fluid Dynamics, May 9-13, 2016, Kobe, Japan  

Intelligent Light has been a sponsor of the Parallel CFD conference for a number of years and this year, we were the primary sponsor of the event held in Kobe, Japan.   Steve M. Legensky, our founder and general manager was invited to join large scale visualization experts Drs. Kenji Ono (Riken and Kyushu University) and Kwan Liu Ma (UC Davis) to give a plenary presentation.  On Thursday, May 12th, he addressed the attendees on "Extract-based Workflows to enable and accelerate Large Scale Production CFD".  The plenary talk following Steve was given by Dr. Eijii Shima of JAXA, long time users of our FieldView software.

"I was fortunate that Dr. Ma gave his talk on 'Visualizing Extreme-Scale CFD Simulations' the previous afternoon so that the stage was set to discuss post-processing directly from the solver code using in situ methods," commented Steve.  "Kwan Liu handles visualization on the leading edge of simulation scale, so I was proud when he referred questions about production engineering-scale workflows to me."  Steve continued with a smile, "The only downside was that the brewery tour and sake tasting came after his talk that evening and I had to lead off the next morning."  Dr. James McDonough (Univ. of Kentucky), a long time FieldView customer, not only introduced Steve at the session, but also serenaded us at the banquet on the piano!

Also at the event, Intelligent Light had an exhibit booth manned by Dr. Atsushi Toyoda, from our Asia-Pacific Technical office.  We got to meet customers and colleagues from all over the world and talk about the latest FieldView features supporting extract-based workflows (such as XDBs).  There was significant interest in integrating VisIt's libsim toolkit in their solver codes as well.  On the Friday morning after the PARCFD event, Intelligent Light held a seminar on extract-based workflows and in situ post-processing at the FOCUS facility, adjacent to the K Computer.  VINAS, Co., Ltd, our FieldView distributor in Japan co-sponsored the event with us.

Seminar: Frankfurt, Germany - "Speed Up Production CFD Workflows with Extract-Based Post-Processing"

Still time to register!

Intelligent Light will hold a seminar in Frankfurt, Germany, on June 22, 2016, the same week as ISC HPC.

The seminar, "Speed Up Production CFD Workflows with Extract-Based Post-Processing" is designed to help those using standardized plots/reports, unsteady CFD, remote HPC computing or large data to achieve greater throughput.

Parallel computing has enabled CFD practitioners to create far more data than can be stored or accessed for post-processing and analysis, making it difficult for engineers and researchers to gain understanding via visualization, exploration and collaboration.

Mr. Steve M. Legensky, Founder and General Manager of Intelligent Light, will present techniques and customer examples that show how extract-based methods have graduated from the research realm to the production environment. 

Yves-Marie Lefebvre, FieldView Product Chief, will introduce the new HPC FieldView software that combines the power of open-source VisIt software with the ease-of-use and productivity of FieldView. He will also demonstrate a pre-release version of HPC FieldView, scheduled for release later this year.

Brad Whitlock, visualization and post-processing engineer in Intelligent Light's Applied Research Group and founding developer of VisIt will showcase our recent success applying in situ techniques to production level workflows that scale from hundreds of cores to over 130,000 cores. Brad will also represent Intelligent Light and VisIt at the ISC Workshop on In-Situ Visualization on Thursday June 23 at 9AM.

This seminar will be held from 9:30 to 12:30 on Wednesday, June 22 at the Mercure Hotel Frankfurt Airport and will be followed by a complementary lunch.

If you are interested in participating, want more information about the seminar or HPC FieldView, simply send an email to sww@ilight.com.  We will be happy to provide details and answer your questions.

There is no charge for participation, but be sure to reply soon as space is limited.

We look forward to seeing you in Frankfurt.

Libsim Improvements to Enable Better In Situ Workflows

This year’s Department of Energy Computer Graphics Forum meeting in Pacific Grove, CA, brought together leading visualization experts from the DOE and DOD to share their experiences developing state of the art software needed to analyze results from future exascale computers. The meeting consisted mainly of invited talks spanning a broad set of topics, including: advances in display wall technology, vendor libraries that maximize performance using hardware, software updates, realistic rendering and in situ analysis.

In my talk, “Libsim Improvements to Enable Better In Situ Workflows”, I outlined the significant reductions in both data size and time spent processing the data that can be realized by extracting surfaces of interest and saving data to the XDB format. These XDB files can then be read into FieldView or XDBview.

Additional performance benefits of this workflow are gained due to the fact that subsequent post-processing does not involve reading large amounts of volume-based results. The performance benefits are magnified when the workflow is applied in situ because the data extraction can be done while data are in the solver memory as opposed to being done after writing volume data to disk. In situ workflow sidesteps the I/O bottleneck associated with writing (and later reading) large amounts of data since it restricts data to only the features of interest, which are a small subset of the original data.

My talk demonstrated Intelligent Light’s commitment to in situ and highlighted the improvements that we have made to Libsim, the VisIt in situ library, that enable it to scale to over 131K cores using the AVF-LESLIE combustion code on the Titan supercomputer at Oak Ridge National Laboratory. We have made numerous enhancements to Libsim that improve its efficiency and ability to seamlessly accept data from the host solver code. For instance, we made enhancements that permit zero-copy passing of data from the solver to Libsim when data are not organized contiguously in memory. In addition, we eliminated several bottlenecks that affected VisIt’s rendering and scaling performance on the Titan machine. We also streamlined the creation of XDB files by developing a prototype parallel XDB library based on Oak Ridge’s high performance ADIOS framework. Taken together, these improvements to Libsim and VisIt set the stage for even larger in situ runs to come and eliminate many barriers to using in situ and an extract-based workflow.
