在32核高性能计算集群上将ANSYS Maxwell DSO提速16倍,通用汽车实现牵引电机设计生产力翻番

在设计电动车(EV)和混合动力车(HEV)的牵引电机时,设计优化工作充满了挑战,因为汽车制造商在这个领域经验不足。电磁仿真在评估设计概念的性能方面起着关键作用,如计算机器的扭矩参数等。过去单次设计迭代上的电磁仿真需耗时数百小时,工程师不得不等待结果,严重影响生产力。通用汽车(GM)研发出一种高性能计算(HPC)环境,它使用32核计算机集群的多余硬件为电磁仿真带来16倍加速,将求解时间缩短到不足5小时。

高性能计算在仿真中的重要价值

高性能计算(HPC)是目前和未来工程仿真的重要组成部分。HPC让业界最佳企业能够更精确深入地了解产品行为,而这种对产品行为的洞察力是不使用详细的仿真模型所无法获得的,仿真模型包括更多几何细节、更大规模的系统和更复杂的物理场。HPC的设计探索功能可让产品开发组织机构探索设计在各种现实工作条件下的性能表现,从而帮助实现可靠的产品性能,并降低质保和维护成本。

这一价值只有通过以HPC为重点的持续的软件开发才能实现。各公司通过大量投入以确保自身产品能够在最新的HPC架构上提供真正高性能的表现结果,比如说使用NVIDIA GPU和Intel Xeon Phi协处理器[1]等硬件加速器。同时还能通过共享内存并行(SMP)、分布式内存并行(DMP)、混合SMP/DMP和“大规模并行计算”等功能提供不断增长的并行计算能力。

Sorting Fact from Fiction - HPC-Enabled Engineering Simulations - On-Premises or in the Cloud - White Paper

HPC may once have been the sole province for huge corporations and national labs, but with hardware and cloud resources becoming more affordable even small- and mid-sized companies are taking advantage. Still, myths and misconceptions stall progress and slow adoption.

Topics covered by this 7-page custom whitepaper include:

  • Calculating TCO for HPC on-premises versus in the cloud
  • Finding the best HPC solution to fit your SMB's needs
  • Licensing, workforce and use-case misconceptions surrounding HPC in the cloud

Smart Strategies for Structural Simulations - White Paper

As engineering demands grow, the size and complexity of structural simulation increases as well. As a result, engineers must understand the best strategies for solving large simulations efficiently. High-performance computing, reduction techniques and variational technology can all lead to efficient and accurate solutions. The trick to solving large problems is not necessarily picking one way to solve every problem but picking the best way to solve the problem at hand.

16X Speedup in ANSYS Maxwell DSO on 32-core High-Performance Compute Farm Doubles Traction Motor Design Productivity at General Motors - White Paper

Optimizing the design of traction motors used to drive electric vehicles (EVs) and hybrid electric vehicles (HEVs) is challenging because automakers have little experience in this area. Electromagnetic simulation plays a critical role by evaluating the performance of design concepts, such as by computing the torque profile of the machine. In the past, it took hundreds of hours to perform electromagnetic simulation on a single design iteration, which hurt productivity by leaving engineers waiting for results. General Motors (GM) developed a high-performance computing (HPC) environment using surplus hardware with a 32-core compute farm that provided a 16 timesx speedup on electromagnetic simulation, reducing solution time to less than five hours.
