《GB/T 38675-2020信息技术 大数据计算系统通用要求》由TC28（全国信息技术标准化技术委员会）归口，主管部门为国家标准化管理委员会。
Introduction
Analysis of the Standard Core Framework
| Module | Mandatory requirements | Recommended requirements | Technological evolution |
|---|---|---|---|
| Computing unit | Multi-processor support, 8GB+ memory | PB-level read and write, hybrid memory architecture | From a single CPU to heterogeneous computing |
| Computing acceleration unit | Independent memory space, PCIe interface | FPGA/ASIC acceleration, batch deployment | AI acceleration chip integration trend |
Detailed explanation of hardware technical requirements
Chapter 5 of the standard clearly requires that the computing unit should support multi-processor collaborative work and virtualization extension, and the memory configuration must meet the following requirements:
- Basic capacity: ≥8GB for a single node
- Extension standard: DDR3/DDR4 and above
- Advanced features: memory mirroring/hot standby technology is recommended
Application case in the financial industry
A bank uses a GPU acceleration unit that complies with Clause 5.3, which increases the efficiency of risk model calculation by 12 times and meets the real-time monitoring requirements of Clause 5.6.
Software Architecture Specifications
Chapter 6 stipulates that the operating system must provide:
- Standardized programming interface (6.2.d)
- Automated deployment capability (6.2.b)
- Fault isolation support (6.2.g)
Virtualization software needs to pay special attention to dynamic migration (6.3.c) and QoS control (6.3.i) functions.
Implementation Recommendations
| Implementation Phase | Key Actions | Standard Basis |
|---|---|---|
| Planning and Design | Evaluate the Selection of Computing Acceleration Units | 5.3.f/g |
| Deployment and Implementation | Configure Memory Redundancy Scheme | 5.2.k |
It is recommended to give priority to meeting the safety requirements of Chapter 8 and at least meet the GB/T21028third level protection standard.
