How HPC Reduces CFD Simulation Time from Weeks to One Day

Some records are broken for glory, while others, like HPC, have more practical results. Compare 2017 Nathan’s Famous International Hot Dog Eating Contest champion Joey Chestnut’s record-breaking feat of eating 72 hot dogs (with buns) in 10 minutes during the annual July 4 contest to ANSYS, Saudi Aramco and King Abdullah University of Science and Technology (KAUST) shattering the supercomputing record by more than 5x. Chestnut was awarded the “Mustard Belt” for the 10th time, $10,000 and an additional 20,000+ calories for his impressive performance. By leveraging high performance computing, Saudi Aramco and KAUST worked with ANSYS to speed up a complex simulation of a separation vessel from several weeks to an overnight run! Continue reading

3 Ways to Boost ANSYS Performance with Intel Technologies

Intel Supercomputing 2017

ISC 2017 in Frankfurt, Germany (copyright Philip Loeper)

My visit to ISC High Performance last month in Frankfurt, Germany re-affirmed my belief that computing innovation shows no signs of slowing down. I participated in an industrial HPC user panel at the event, which has traditionally focused on big supercomputing solutions for government and research institutions. The fact that this year’s ISC broke attendance records and dedicated so much time to industry sessions shows how much HPC has become entrenched in other industries.

We have been working with Intel on a few innovations that I wasn’t at liberty to discuss at ISC, but can now share with you that Intel announced its new processors and improvements to their accompanying technologies yesterday. We have been working with Intel to benchmark ANSYS software on the new technologies before their release, so that our mutual customers can immediately see what benefits they’ll receive. Here’s a sneak peek at the results. Continue reading

Accelerating Innovation Through HPC-Enabled Simulations

HPC Ferrari RacesMany engineers are using powerful simulation software but are still not deploying HPC to the full extent. Case in point, I presume most of you have heard about the 24 Hours of Le Mans race. There is one starting June 17. I find it very exciting, not least because teams of three drivers per car compete to complete the most laps around the 13.629-km Circuit de la Sarthe in 24 hours! The race cars reach more than 320 km/h on the straightaway, spending most of the 24 hours at full throttle.

Imagine the roar of the engine drowning out the cheers of the crowds as you speed smoothly around the track in a finely tuned (thanks to simulation) race car. Now imagine the track is a country road or dirt road, not so smooth or speedy now, is it? Continue reading

ANSYS HPC: On to a Million Cores!

ANSYS CFD is on the verge of a second renaissance in high-performance computing (HPC). The first, spanning more than a decade, has seen tremendous leaps in both the depth and breadth of HPC capabilities. Depth (or heights, rather) in the size of the scalable clusters — first 1000s, then 10K, and recently 100K core counts — and breadth of coverage across solvers, physics, post-processing, even file I/O, covered the gamut of high-performance simulations. The trend, in fact, is exponential, as evident in this chart, and spans many years of ANSYS Fluent software releases. While there are other impressive scientific scalability demonstrations, ANSYS Fluent set the standard for industrial HPC CFD simulations. Continue reading

Defining the Future of Cloud-based Engineering Simulation: ANSYS at AWS re:Invent 2016

Each year the cloud faithful converge on Las Vegas in the fall for AWS re:Invent. This year’s event delivered exciting announcements for ANSYS users interested in performing engineering simulation on the AWS cloud.

With well over 30,000 attendees, the 2016 conference was too big to be contained within the expansive Venetian hotel/Sands expo complex and it spilled across into adjacent facilities (comfortable shoes were a requirement). Wednesday’s keynote session by Andy Jassy, CEO and Thursday’s session by Werner Vogels, CTO highlighted the growing reach of AWS. The conference featured a staggering number of new features, services and some powerful new hardware. Continue reading

Why Do Supercomputing Records Even Matter?

Some world records are the stuff of legend. The official land-speed record is 763 mph.  The tallest man living measures 251 cm. The fastest ball bowled by any bowler is 100.23 mph and the heaviest vehicle pulled over a level, 100 ft course weighs 68,090 kg.  Compared to these feats, records for supercomputing can seem a little flat. However, they are no less impressive and indeed, and stand to have a far greater impact on our day-to-day lives. Continue reading

SGI and ANSYS Achieve New World Record in HPC

Looking back at the past couple of years of extraordinary joint engineering projects SGI and ANSYS have undertaken, it is clear to me that when a synergetic hardware and software partnership is established you, our joint customers, are the clear beneficiary. To that end, I would like to walk you through four such examples.

The first example was outlined over a year ago in my ANSYS guest blog, “Solving the Impossible Electromagnetic Simulation with HPC” where with a “grand challenge” benchmark we jointly demonstrated that the SGI® UV platform and ANSYS HFSS software could solve very large, high frequency electromagnetics problems like cosite analysis and radar cross section (RCS) analysis, as well as allow multiple frequency sweeps to be run without running out of computer system memory. Continue reading

Maximizing Engineering Throughput with Pay-Per-Use Simulation in the Cloud

My colleagues Steve Del, Giovanni Petrone and I often discuss the benefits of moving engineering simulation to the cloud, marshalling greater computing resources and faster processing on high-performance computing (HPC) solutions. While most companies would find this compelling, budget-conscious companies are concerned about the costs. The missing piece is a pay-per-use simulation business model, where  you use what you need, when you need it, and only pay for what you use.

Well, now that piece is in place. Last week’s release of ANSYS Enterprise Cloud adds support for ANSYS Elastic Licensing™, enabling you to fully leverage the pay-per-use business model on the public cloud for both hardware and software. Continue reading

BorgWarner Goes Full Speed with ANSYS HPC Parametric Packs

It doesn’t matter what car you drive — it could be a snazzy Ferrari or a humble FIAT Punto — ultimately what we’re all looking for is a car that performs well and maybe saves us a little money at the pump.

The upcoming joint ANSYS-ESTECO webinar on September 15th will discuss just how important a single component, in this case, a tensioner arm, can be. Chain tensioner arms may not be as well known as pistons and gearboxes, but, by maintaining the correct amount of tension on the chain at all times throughout its duty cycle, they are important for reliable operation of the accessory chain drive system. The chain tensioner also helps protect other components, such as the alternator and water pump, from undue stress and premature failure. A well-designed chain tensioner can also help boost engine performance and efficiency. Continue reading

How to Greatly Reduce HPC Costs for Engineering Simulation on Cloud

Most simulation engineers with a hunger for high performance computing (HPC) have looked longingly to the cloud. Cloud computing has the potential to provide virtually unlimited access to HPC, enabling larger simulations and more design variations to be done in less time, since many machines working in parallel can solve even very large problems quickly. While the cloud offers much more than unlimited computing power, it’s those HPC resources that provide the strongest pull to the cloud. The question we seek to answer here is, “is it possible to get cloud-based HPC at very low cost?” Continue reading
