The growth of CAE tools has followed the industry through a familiar progression of technologies, starting out on mainframes in the 1980’s. Then pre- and post-processing migrated to the desktop in the 90’s, while solving continued on HPC systems, especially for compute-intensive analysis. The 2000’s have seen a continuous shift to more solving on the desktop with bigger, faster, parallel systems being used for the biggest problems.

CAE tools are now being used by mainstream engineers rather than CAE specialists, so  more engineers are now able to run larger and more complex models. Smaller models may still be run on the desktop, but HPC systems are still required for larger, more-accurate models. Another driver for increased compute power is automated workflows. Parameter sweeps for geometric changes or boundary conditions can mean that 10 or 20+ models may need to be computed. With a matrix of parameters, run counts can get even higher.  

Automated workflows enable optimization, with systems searching through a complex design workspace often running hundreds of simulation models in the process. Multi Disciplinary Optimization (MDO) pushes the envelope on this technology, linking multiple analysis tools. HEEDs, ModeFrontier and ANSYS DesignXplorer are examples of tools in which runtimes can be drastically reduced by deploying HPC via the Rescale platform.

Water Pump Efficiency Optimization Process
A CAD tool can control many geometric parameters to automatically create new solid models for CFD analysis. With a lot of variables, design spaces can become huge, where even the best MDX search engines still needing to run perhaps 100 different CFD models to find a better design. If each water pump model is 10 million cells, it may converge in 24 hours on a 64 core on-premise HPC system. That’s still 100 days! (Too much for a real world engineering problem.) There are two ways to accelerate this with the Rescale ScaleX platform:

  1. Increase the core count per job (Running each on 256 cores may reduce runtime per point to 6 hours), or
  2. Run multiple jobs concurrently. Technically you could run all 100 points at once on the Rescale ScaleX platform, but most optimization search engines use the results from previous runs to guide the direction of new runs. Typically only 10 (or less) of the 100 points can be run concurrently. At 40 runs per day, the Rescale platform could still condense the timeline from 100 days to 2.5 days!           

Bicycle Aerodynamics Analysis
Many bicycle magazines from the last two years contain reviews of a series of bicycle brands being compared in a wind tunnel. Companies will also try to emulate the process with CFD.

The manual workflow for this process:

  • Build base CAD model
  • Identify key geometric parameters
  • Apply parametric variables to CAD model
  • Export CAD model
  • Create CFD mesh
  • Solve for aerodynamics
  • Post-process for drag

Then repeat 20 times for different yaw angles. Repetitive and exhausting.

Imagine an automated process where parametric CAD geometry is used to create new geometries followed by CFD to evaluate aerodynamic performance of the frame. The numerical computation becomes substantial, and even though the actual man-hours is reduced the elapsed time is still a problem. 

Using the DOE functionality within the Rescale platform, all 20 models above could be run concurrently. It is a simple way for any company, including SMBs, to get instant scalability and power. Instead of a bicycle aero CFD model taking 24 hours on 16 desktop cores, you can use 196 fast cores on the Rescale platform to turn it around in 2 hours. In addition, you can run 20 models at once. The GANTT chart looks very different when the whole virtual wind tunnel CFD test can be completed in 24 hours instead of 20 days!

The need for faster, easily-accessible compute power is now greater than ever. How can companies really get the best from CAE tools when they are continuously stymied by limited resources? Project timelines planned using a GANTT chart can often show CFD project runtimes in days or weeks, a dominant part of the full project timeline.

This has been the accepted norm for many years. But now we can show you how the Rescale cloud platform can remove those roadblocks and condense project timelines!

Level the Playing Field! 
Many engineering companies or consultants are cautious to accept work where a large investment in computer hardware is required. Now, with Rescale’s ScaleX cloud HPC platform, any company can deploy adequate resources for the most complex CAE calculations. This is a market-changing dynamic. In the past, the most successful engineering companies would deploy large on-premise HPC systems. Much of their value to their clients was the availability of those systems. Now any group can deploy large HPC resources on-demand using the Rescale platform!

IBM Bluemix offers our customers an impressive array of leading high-performance computing (HPC) infrastructure, including bare metal servers and the latest GPUs, on an hourly basis to customers all over the world. But as HPC technology gets more advanced it takes more knowledge to leverage effectively, and we recognize that many times the people who need HPC aren’t experts in HPC; they’re experts in something else. They’re data scientists, automotive and aerospace manufacturers, and bioinformaticians. With challenging, high-stakes problems to solve, the intricacies of HPC implementation is just a hurdle to overcome on their quests.

Rescale’s web-based platform for running HPC on the cloud delivers the performance these engineers and scientists need in a turnkey, user-friendly experience. Rescale’s ScaleX platform gives users control over their data, hardware, and software while automating the complex tasks of HPC configuration and optimization. Running on IBM Bluemix infrastructure, Rescale makes sophisticated compute capabilities accessible to the users who need it most.

Here are just a few ways that Rescale simplifies HPC for all those trailblazers, helping put IBM Bluemix’s world-class HPC infrastructure network to work curing cancer, finding life on Mars, and predicting the future:

  1. Automated cluster configuration
    Building out your HPC cluster each time you want to run a job can be time-consuming and complicated, especially for the HPC novice. Doing hours of legwork just to get your computations started can undermine the value of being able to burst to the cloud exactly when you need to making the user’s task as simple and quick as choosing their hardware and cluster size and clicking “Submit.” It just takes a few clicks to spin up a cluster.
  2. Broad portfolio of pre-tuned and optimized software applications
    When a customer comes to IBM Bluemix, they install their own software based on their specific needs. Then they run benchmarks and tune their software to run on IBM Bluemix infrastructure. Again, this takes wizard-level HPC knowledge to do, and if you skip this step your performance will degrade or your problem might not even be solvable in the cloud. Rescale has a team of HPC, CAE, and deep learning experts that have automated and productized the tuning and optimization process for That saves a lot of time for our shared customers, and ensures they effortlessly get the maximum performance out of our hardware. Plus, Rescale offers hourly on-demand licenses, cloud license-hosting, and license proxy tooling to simplify the tangle of cloud licensing models software users must navigate if they want to leverage the cloud.
  3. Cloud management features
    Using the cloud to infinitely scale out your computations is game-changing, but it presents its own set of challenges at enterprise scale. Rescale’s has an administrative portal for IT teams to manage budgets and permissions for large, multi-disciplinary teams and projects. It also integrates easily into existing private infrastructure hardware and schedulers for seamless hybrid cloud deployment. Collaboration features allow users to share jobs with their colleagues in real-time, without having to download or transfer large files. These features and others give enterprise employees the raw power of HPC while ensuring the organization is productive, cost-effective, and secure.

In short, Rescale’s synergies with IBM Bluemix open the doors to world-class HPC, increase utilization of our infrastructure, and make them a valued partner. We’ve got some big stuff in the pipeline for 2017 and beyond, and we’re excited to bring them to market with Rescale at our side.
