The first national standard on high performance computing (HPC), GB/T 45400-2025, Information technology—Cloud computing—General requirements of HPC in cloud, was issued by the State Administration for Market Regulation (National Standardization Administration of China), which will come into effect in October.

The development of the voluntary national standard was led by Alibaba Cloud, China Electronics Standardization Institute and other institutions. It lays the foundation for the large-scale application of HPC in cloud, and promotes the construction of China’s computing infrastructure towards a standardized and intelligent phase.

As a new type of HPC, HPC in cloud provides elastic and extendable HPC services externally based on cloud infrastructure. Currently, traditional HPC has been applied in fields such as large model training, autonomous driving, life sciences, industrial manufacturing, and semiconductor chips, and is gradually blending with other industries.

However, traditional HPC often has complex architectures, poor scalability, performance bottlenecks, and high prices, which hinders its adoption in many enterprises and makes HPC in cloud a new choice for enterprises.

GB/T 45400-2025 delineates definitions of the infrastructure of HPC in cloud, collaborative scheduling of resources, full-stack security and trust system, and other key technical indicators. It covers the entire process of cloud HPC services, including design and development, deployment and operation, and performance evaluation, providing a guide for various industries regarding the design, implementation, application, and selection of such products.
