“Many hands make light work” is as true today as it was in the 16th Century when John Heywood first coined the phrase. The historical perspective of “piecework” now gives way in modern parlance to the idea of “global collaboration”. Current trends point conclusively to the value of an always-available, secure, and collaborative web-based environment for scientific computing.  The world’s leading product designers, scientists, and engineers are globally dispersed. They share, if not a spoken language, a common engineering perspective and solution literacy; what I would call a “Cloud Of Everything” unites them, and accelerates their productivity as never before.

The idea of a “Cloud of Everything” (CoE) is distinct from the notion of an “internet of everything”—or IoE as Cisco has evangelized—which promises to unite “people, processes, and data”. The CoE in the context of web-based simulation proffers the ability of one user to initiate a workflow in a secure, scalable, on-demand cloud environment and to share those temporal results in rapid fashion with a colleague half a world away for analysis, refinement, and additional simulation to create superior products.  The “Cloud Of Everything” is really the global workspace where complex computational problems get solved.

What distinguishes this workgroup organizationally is the interposition of a common platform that freely enables multiple solvers, optimizers, and workflows to support accelerated global development cycles in key technical verticals. It is almost a given now that webmail, gaming, video conferencing, file transfer, and data migration, amongst others, are enabled and accelerated by the global web – now we can use the same perspective when we think about web-based CAE in auto, aero, energy and biosciences.

Twenty years ago, visionary novelist and essayist William Gibson observed that the future was “already here – just not very evenly distributed”. In 2014, the global distribution of compute resources supporting the management of Big Data lends itself equally well—given a shared simulation platform—to the challenging engineering and scientific work of the world’s leading research enterprises. And the information that is the yield of this computational work is a subset of IDC’s prediction that by 2020 (that’s only 5 years away!), the information that enterprises will manage will have grown 14x!

As an example, enterprise IT managers today are making an increased number of  infrastructure “own vs. lease” decisions for engineering teams in their organizations. The volume, velocity, variety, and value of research data requires these managers to carefully govern the information yield that forms the intellectual property of the enterprise. The “Cloud Of Everything” addresses both the demands of the IT practice and engineering schedule by providing  both the research and information management  resources needed by each.  Additionally the “Cloud Of Everything”  supports the well-documented, inexorable trend to move data out of the campus and into globally-shared compute resources, while enabling critical information back to base.

Conclusion: whether we are talking about ERP, PLM, PDM, –  or any of the essential elements of the enterprise that require critical simulation, the bridge between human and CPU requires a robust, reliable, and collaborative workspace–the shared simulation platform provides this universal workspace that truly allows those “many hands” to make lighter work.

With the 2014 World Cup coming to a close, we’ve seen great shots and great saves. However, what is the science behind the curving shot that causes so much commotion and so many great goals. Rescale and Convergent Science teamed up to show how the cloud and computational fluid dynamics (CFD) can help us understand the science behind the spinning of the black and white ball that has so  many of us asking, “How did they do that?”.

Convergent Science modeled this phenomenon to show us just what it takes to get the “bending” of the ball in mid-air.  Using their computational fluid dynamic (CFD) product CONVERGE™ , with its fully coupled automated meshing process, they created a spinning soccer ball model. Rescale then ran the model on their on-demand cloud simulation platform, using customized high performance computing (HPC) hardware and the CONVERGE™ CFD software. Rescale and Convergent Science have a technology partnership that allows engineers and scientists to quickly run improved computer-aided engineering (CAE) simulations on demand in the cloud. CONVERGE’s automated meshing technology significantly reduces the time users need to set up simulations, while Rescale’s fully customizable platform allows users to drastically decrease the simulation runtime.

The Analysis

The findings were impressive. Applying the force of the kick to the bottom right or bottom left of the ball creates a lift and spin effect that ultimately causes the ball to move while in mid-air.  Assuming the average kicking velocity of a professional kick being 23 meters per second (55 MPH) a spin of 24 revolutions per second is imposed on the ball, resulting in 10 feet (3 meters) of lateral movement per second.  Figure 1 and Figure 2 show a visualization of the velocities present in such an analysis.

Figure 1: The velocity of a spinning ball creates a vortex that allows the ball to curve.

Figure 2: The vortex of the spinning ball is shown in more detail.

Rescale is a cloud simulation platform that provides on-demand, scalable compute configurations coupled with fully integrated simulation software. Rescale and AVL recently announced a technology partnership that allows AVL FIRE® users to burst their simulations into the cloud on demand. Once the user has created their models, they only need a web browser to quickly log in to Rescale’s platform, select the software and hardware, upload the input files, and run their simulations.

Maik Suffa, Product Manager at AVL for the 1D and 3D CFD software products AVL BOOST and AVL FIRE®, asked Cliff Arnold, founder and owner of Sage Physics Engineering and a long-time user of FIRE®, to test the recently announced joint solution for running AVL software on Rescale’s cloud simulation platform prior to its public availability.

“I was skeptical when AVL asked me to test a cloud computing platform. Uploading data, running simulations in batch mode, getting results back on my workstation … could that be easily handled? What would be the performance of the system? Can running simulations in the cloud provide real benefits?” Cliff articulated what many AVL customers may also wonder about cloud computing. “But I was also curious, so I gave it a try.”

“Once I created a Rescale account,” Cliff explained, “I could initiate my workflows in the cloud immediately. This was accomplished very quickly, requiring only my browser. I also received login instructions and tutorials on how to get started right away via email. Online demos and documentation provided on Rescale’s website were also quite helpful. Updating the JAVA version on my workstation allowed for quick upload and download speeds using Rescale’s File Transfer Manager.”  

“Following the instructions given on the site, I uploaded my data to the cloud and quickly managed to start my test cases. Once submitted, my jobs ran after only a 2 to 5 minute period to provision the cluster. Essentially no wait time,” Cliff noted. “I did not experience any trouble when downloading the simulation results after the runs were complete. The performance of the hardware managed by Rescale meets or exceeds industry standards and provides access to a virtually unlimited number of cores. With the scalability and robustness of both Rescale and AVL FIRE®, I was able to reduce the simulation time of my cases to an almost arbitrary runtime by significantly scaling the number of processors used for my jobs.”

While simulations are running, users have the ability to track the status of their jobs and to view output files generated by the simulation. Since the work is handled entirely in the cloud, it does not affect users’ internal desktops or workstations. Once the job is finished, users will be alerted by email so they can view and download their results. Collaboration and data management features built directly into the platform allow users to easily copy simulations, share jobs with colleagues, and determine what results data needs to be downloaded.

When asked whether he’d use Rescale to  run AVL FIRE® simulations for his and his clients’ production use, Cliff responded: “While I’ll continue using my own licenses and hardware it is not an either/or decision. The experiences I gained in the cloud are very positive ones. This new joint solution that AVL and Rescale offer allows access to additional licenses and computing power at any time and to any extend. While the software and hardware resources I possess are limited, this is not the case in the cloud. With cloud computing, I’m able to execute simulations without delay – no occupied licenses or overloaded hardware. It also provides the ability to run larger grids and to deploy more resource demanding models like LES or complex reaction chemistry. Whenever there is a demand I’ll use this service. It will help to shorten the time to deliver project results. My clients will certainly like it.”
