Alibaba Cloud EHPC Empowers New Manufacturing — SAIC Simulation Computing Cloud (SSCC)

As the collaboration between SAIC Motor Passenger Vehicle Corporation and Alibaba Cloud progresses, multiple Alibaba Cloud technologies are being applied to SAIC’s core business of auto development and design. SAIC Motor, with the help of Alibaba Cloud, has upgraded its engineering development simulation capabilities and has promoted simulation computing efficiency by 25% thus allowing engineers to focus more intently on product design and performance optimization so as to deliver world-class products. This is evident with the launch of the MG X-Motion concept car made at the 2018 Auto China Show Beijing International Automotive Exhibition. Its production version has repeatedly been optimized for superior performance using SAIC’s simulation computing cloud platform.

A typically representative new manufacturing project is the simulation computing hybrid cloud co-built by SAIC Motor Passenger Vehicle Corporation under SAIC Motor Corporation Limited (generally referred to as “SAIC Motor Passenger Vehicle Corporation”) and Alibaba Cloud. SAIC Motor Passenger Vehicle Corporation, a wholly-owned subsidiary of SAIC Motor, is responsible for the R&D, manufacturing and sales of all of SAIC Motor’s proprietary brand vehicles. It owns two vehicle brands — Roewe and MG — and has three technology R&D centers located in Shanghai, Nanjing and the UK as well as three manufacturing sites at Shanghai Lingang, Nanjing Pukou and Longbridge in the UK.

Challenges of Production-Level Engineering Simulations

Massive Urgent Requirements

Lagging Resource Iteration

Poor User Experience

SAIC Simulation Computing Cloud (SSCC)

SSCC is primarily composed of Alibaba Cloud’s public cloud clusters and clusters built by SAIC Motor Passenger Vehicle Corporation. Data interconnectivity and unified scheduling for computing resources are delivered by using a high-speed leased line. Alibaba Cloud’s public cloud clusters primarily provide the following computing resources.

HPC Computing Clusters

NAS Shared Network Attached Storage

Graphic Processing Cluster

Statistics show that an average of more than 500 multi-discipline simulation computing jobs are carried out per day on the SSCC platform. These include collision analyses, structure rigidity analyses, fluid analyses and NVH analyses. They also simulate running statuses of vehicles, engines and other parts. Thanks to performance improvements brought about by Alibaba Cloud super-computing clusters, it takes less time to compute and find solutions compared with previous use of local clusters; user jobs’ queuing time has also been significantly reduced. In addition, the majority of job data flows are in the closed loop of Alibaba Cloud public cloud cluster. This reduces the pressure on local storage and reserves more historical engineering data, making it easier for engineers to do a comparative analysis based on multiple scenarios.

With Alibaba Cloud, SAIC Motor Passenger Vehicle Corporation has upgraded its engineering development simulation capabilities and has promoted simulation computing efficiency by 25% thus allowing engineers to focus more intently on product design and performance optimization so as to deliver world-class products. The MG X-Motion concept car made its global debut at the 2018 Auto China Show Beijing International Automotive Exhibition. Its production version has repeatedly been optimized for superior performance using SAIC’s simulation computing cloud platform.

You Jin, an engineering application support senior manager in the Information System Department at SAIC Motor Passenger Vehicle Corporation said “Alibaba Cloud and the HPC clusters built by SAIC deliver excellent performance alongside flexible and scalable resources, dramatically reducing the pressure on R&D and ensuring project development progress.” Qiang Bin, infrastructure director of SAIC Data and Information Systems, said “Alibaba Cloud’s public cloud has a proven governance model which complies with SAIC’s security requirements; the flexible resource activation of the cloud also reduces investment and labor cost which would have been incurred by self-built clusters.” The application of hybrid cloud technologies boosts SAIC’s global research and development, and aligns with SAIC Motor’s R&D goals for internationalization of production; this efficient collaboration model can quickly extend across the entire product R&D chain, allowing SAIC Motor Passenger Vehicle Corporation to quickly release to terminal markets its vehicles and travel services such as those which are targeting the Four New Goals of electrification, smart networking, sharing and globalization.

Features of Alibaba Cloud EHPC Technology

1. Excellent Performance

These clusters provide world-class performance.

2. SLA Assurance

3. Hybrid Cloud Architecture

4. Automatic Scaling (*E-HPC Support)

5. Fast POC

During POC, you can choose to temporarily activate more resources in the environment than originally planned for so as to accelerate the CAE application verification process.

6. Data Sharing and Interconnectivity for Linux/Windows

7. Closed Loop with Elastic Data Volumes

Even if data usage exceeds planned volume (e.g. a purchased volume package), the 10 PB public cloud NAS storage can ensure that data is written successfully. Computing is almost free from bucket limitations, therefore business continuity can be ensured.

8. Collaborative Development Enabled by Perfect Account Management

9. Perfect SaaS Service Capabilities

Interactive applications: HyperWorks, EnSight, Converge Studio, Star-CCM+, Fluent, MSC.Admas, Abaqus, NCode

Computing applications: LS-Dyna, Converge, Star-CCM+, Fluent, MSC.Nastran, NX.Nastran, MSC.Admas, NCode, OptiStruct, Abaqus, Star-CD, iSight

10. Granular Business Scheduling Capabilities

  1. Resource Quota Scheduling: This platform imposes quota limitations on fixed resources and public resources based on department and project group properties. This can meet rigid computing demand at the department and project group level, and also implement elastic resource scheduling at the enterprise level.
  2. Unified Scheduling of IaaS Resources: With the device grouping policy, this platform schedules on-premise HPC devices and Alibaba Cloud cluster instances in a unified manner, ensuring efficient and concurrent running of a single computing instance as well as fast resource scheduling for a lot of tasks.
  3. Unified User Data View: This platform can manage both on-premise storage and Alibaba Cloud storage. A unified user data view is designed to provide excellent user data management experience. CAE data can perform smart matching with neighboring resource nodes, and then start computing or interaction operations.
  4. Preemptive Scheduling During Idle Time: This platform features some policies policy that enable preemptive scheduling during idle time so as to meet requirements of some specific computing scenarios. Quote limits on predefined resources can be exceeded during a specified period to maximize computing resource usage.
  5. Advanced License Scheduling Mechanisms: To comply with the features of industrial software licenses, this platform integrates a range of advanced scheduling mechanisms that allow users to control license resources reserved for device node groups and user groups.

Summary

If we review the journey this project has taken and outlook on the future of China’s industrial independent research and development, we believe SSCC will become an important milestone in the practice of cloud computing, and shows Chinese enterprises the true capability and huge value of intelligent industrial development cloud:

SAIC Motor has established an elastic supply system for computing resources and flexible governance mechanisms. SAIC has also implemented granular development resource management as well as a secure and reliable closed loop of core development data production. These achievements will undoubtedly inspire innovative and intelligent development and further increase core development productivity; Alibaba Cloud is committed to delivering comprehensive and efficient computing engine services for “intelligent manufacturing in China” and has made great significance in the industrial simulation computing field.
