ANSYS HPC Commitment

• High Performance Computing

(HPC) adds tremendous value

to your use of simulation

– Enabling insight

– Enabling productivity

• ANSYS is focused on HPC

– Major innovations in ANSYS

12.0 and HFSS 12

– Ongoing investment to

expand capability and exploit

emerging technologies


Business Value of ANSYS HPC

• ANSYS HPC enables the enhanced insight you need to succeed

– High-fidelity, detailed and accurate understanding of product

performance

– Insight you may not be able to get in any other way

– Insight you need in order to avoid costs associated with product

failure, troubleshooting delays, or lack of product innovation

• ANSYS HPC enables productivity

– Faster simulation turnaround and ability to consider more design

ideas

– Faster decision making, “right” decisions to keep projects on track

“to out-compete is to out-compute.”

ANSYS HPC

Delivering the Business Value

“There is ever-increasing pressure from the market to ship

products with shorter development cycles and increased

design complexity. HPC enables us to achieve this goal

via shorter and more effective design cycles.”

- Santosh Shetty, Reliability and Component Engineer, Microsoft

Application: Thermal cycling loads in Xbox console

Software: ANSYS Mechanical

HPC Solution: Solution in 12 hours using 16-way parallel

Compared to 4 days on single workstation

Business More robust final product based on insight

Solution: gained from simulating multiple design scenarios


ANSYS HPC

Delivering the Business Value

“Unlike other teams, we didn’t plan to build a second wind

tunnel. Instead, we have used the key relationship

commitment with our HPC partners, including ANSYS, to

develop and exploit the expanding potential for CFD…”

-Mario Theissen, Director, BMW Motorsport

Application: Automotive external aerodynamics

Software: ANSYS FLUENT

HPC Solution: High-fidelity results, fast,

using 100’s of processors per simulation

Business Ability to assess performance enhancing

Solution: design changes within two week race window


Enabling Insight

ANSYS HPC

Multiphysics Capable

• ANSYS HPC solutions support multiphysics

– Single solution enables parallel processing for

fluids, structures, thermal, and electromagnetics

– Eliminates the need to separately acquire and

deploy parallel processing for separate simulation

domains

– Increases the value from your overall investment

in high performance computing and ANSYS

multiphysics solutions


ANSYS Investment in HPC

• ANSYS invests to deliver top performance and capability

• In our 2009 releases:• Ideal parallel scaling to 2048 cores and support for one billion cell

simulations (fluids)

• Teraflop performance and scaling to 512 cores (mechanical)

• Support for parallel file I/O (fluids)

• Introduction of domain decomposition (high frequency electromagnetics)

“ANSYS has consistently focused software design on the full range of

computing platforms ― from desktop to supercomputer ― with their

technology yielding great performance on the latest high-performance

computing (HPC) solutions. This ensures that our mutual customers can

tackle ever more complex and high-fidelity simulations while still achieving

the turnaround time required for product development decision making.”

― Richard Dracott, General Manager, HPC Division, Intel, U.S.A.
