Six Myths of High-Performance Computing

six myths of high performance computingLooking back at my notes from conversations with many engineers during our recent ANSYS Convergence Conferences, I must admit that I still came across some myths and misconceptions about high-performance computing (HPC) for engineering simulation. Let me share six really striking ones with you:

  1. HPC is available on supercomputers only
  2. HPC is only useful for CFD simulations
  3. I don’t need HPC – my job is running fast enough
  4. Without internal IT support, HPC cluster adoption is undoable
  5. Parallel scalability is all about the same, right?
  6. HPC software and hardware are relative expensive

In this blog, I’ll address — and attempt to dispel — the first 3 myths. Continue reading

Privilege of Having Strong HPC Technology Partnerships

As each week begins, I realize what a privilege it is to work with leading HPC technology providers like Intel, NVIDIA, Dell, HP, IBM and many others. Apart from the pleasant inter-social aspects of our weekly meetings, these collaborations enable us to provide simulation solutions optimized on the latest computing platforms. I strongly believe this is necessary because the computing landscape changes so quickly. Our customers want to take advantage of the latest HPC technologies and expand the scope of what they can accomplish with simulation.

As a result of this partnership, ANSYS and NVIDIA have developed GPU-accelerated solvers and algorithms across our full range of multiphysics solutions. We were one of the first commercial engineering simulation providers to introduce structural mechanics support of GPU computing, and we released the first major commercial GPU-accelerated fluid dynamics solver of its kind with ANSYS 15.0.

The ROI of Engineering Simulation

It is always my pleasure to meet with our customers and learn about how they deploy engineering simulation software in their organizations. At ANSYS, we are fortunate to work in a field that holds so many exciting uses for engineering simulation. The industry has come a long way since those days when management was skeptical about the value of performing simulations. But are organizations getting a good return on investment, or ROI?

Today, when I ask customers what they see as their current challenges, many of them tell me that they are so reliant on simulations that they are now being asked to do even more with little or no increase in the human resources made available. And as organizations rely even more on engineering simulations, it is not surprising that simulation teams are being asked to show greater return on investment. What I find surprising is that even when organizations are asked to reduce overall expenses, we see an increase in budget for deploying engineering simulation! Continue reading

Harnessing Energy Through Simulation

Maybe you’ve never thought about it, but we are living on a spaceship called Earth. It’s a big one, with more than 7 billion people on board, traveling at about 108,000 Km/h (67,500 mph) in the solar system, while spinning in such a way that, if you are on the equator line, you are moving at more than 1,700 Km/h (1,000 mph). Amazing, isn’t it?

In our travel through the universe, we are protected from outer space by our pressurized canopy: a 12 Km-thick barrier limited by an ozone layer that acts as a shield against radiation and small asteroids. It also allows us to breathe fresh air. It’s a very complex ship, with systems designed to provide the passengers (us) with anything we need to have a very pleasant journey: food, energy, water and fun. But it was designed 4.5 billion years ago, and there were no human beings at that time asking for so much energy to cool down their houses in summer, heat them up in winter, drive a big car, fly in a plane, or produce goods.

Four Out of Top Six F1 Racing Teams Powered by ANSYS

If you’re like me — a passionate fan of Formula 1 — you were probably on the edge of your seat during the last race of the season in Brazil, during which either the Red Bull of Sebastian Vettel or the Ferrari of Fernando Alonso could have won the championship. After a season of 20 F1 races, the fact that the contest was so close is a measure of the margins these teams work with. Anyone who has been to a race and witnessed these race cars firsthand knows exactly how close to the edge the cars and drivers are.

F1 Vehicles Most Technologically Advanced

F1 vehicles are the most technologically advanced in the world; they need to adapt each year to changing regulations. This often results in a team redesigning the car’s roughly 4,000 components to meet the demands of performance and safety. But not only that, engineering teams are continually improving performance between races — often having only two weeks between races to make a performance impact. With lap times for the leading cars differing by fractions of a second, improperly executing these changes from one circuit to the next can be the difference between being on the podium and not scoring any points.

CFD Drives Marussia Formula 1

image of Marussia Formula 1I read my coworker Gilles’ blog last week week, the one where he discussed Formula One, wind tunnels and CFD. It brought to mind an article I’d read a few months back geared around how software engineers power Marussia. I thought I’d use this information to jump into Gilles’ conversation from a different angle.

While there are typically hundreds of people on a racing team who work tirelessly behind the scenes to make the car quicker, using a computer and the right software is an essential part of what it takes to win a race, much less a season of races. Continue reading
