Scalability
Why is it important?
• Demand for simulation increases steadily
• More physical effects can be simulated
• Model size increases
• Evolutions in Hardware platforms
Copyright © 2010 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.
Scalability - Hybrid Technology
• Combine SMP and MPP (domain /
loadcase decomposition) technology
• Leverage increasing number of
cores per cpu
• Technology available in
• RADIOSS
• OptiStruct
• AcuSolve
