Saisi x Volcano Engine | High-precision synchronization clock helps ByteDance's first computing power center in East China come into operation

Saisi's synchronous clock provides all-round support to the Volta Engine Yangtze River Delta Computing Power Center, helping ByteDance's Volta Engine to create a "new universe in the cloud".

1. The Volta Engine Yangtze River Delta Computing Power Center is a key project of the Wuhu "East Data West Computing" data cluster. 

It is the first computing power center of ByteDance's in East China. The center is a major project of the "East Data West Computing" data cluster in Wuhu, with a total investment of 8 billion yuan. It will deploy 21,800 server cabinets and be equipped with a 220kV independent substation, carrying multiple missions such as AI large model training, cloud computing, and regional digital economy development.

Facing the challenges of the coordinated operation of tens of thousands of devices and the scheduling of millisecond-level computing resources, the Volta Engine Yangtze River Delta Computing Power Center has introduced Saisi synchronous clock (which previously served the "East Data West Computing" GuanYang Hub Node in Gansu Province). Through millisecond-level time precision, it ensures the data consistency of the distributed system in the Volta Engine Yangtze River Delta Computing Power Center, the accuracy of AI training results, and the reliability of dynamic scheduling of computing resources.

As a strategic partner of leading cloud service providers such as Alibaba Cloud and Tencent Cloud, this cooperation with ByteDance's Volta Engine Yangtze River Delta Computing Power Center will enable Saisi to provide all-round support for its "infrastructure - business engine", helping ByteDance's Volta Cloud to create a "new universe in the cloud".

In the collaborative matrix of over 20,000 devices in the Volta Engine Yangtze River Delta Computing Power Center, a 1 microsecond error could cause a chain collapse of computing resources. From the gradient synchronization of AI large model training to the millisecond-level scheduling instructions across regional computing power centers, time precision directly determines the success or failure of the business.

According to relevant research, the requirements for time synchronization in computing power centers mainly manifest in distributed collaboration, AI training scenarios, and network performance optimization. Distributed system collaboration, micro-service calls across servers/cabinets need millisecond-level time alignment, distributed database transaction logs need strict time sequence guarantee; in AI training scenarios, if the parameter update of the GPU cluster is delayed by 1 millisecond, it may cause a 20% increase in training cycle and an increase of millions of times in single-task cost...

This time, the Saisi synchronous clock selected by the Volta Engine Yangtze River Delta Computing Power Center is a high-precision time synchronization device that can achieve millisecond-level NTP output precision within the local area network and support the computing power demand of an extremely large scale. The product can provide ≤1ms precision NTP timing for downstream devices by tracking satellites, can meet the real-time response requirements of the computing power center for every trillion trillion trillion calculations, and provide a "zero-zero error" time reference for AI training, high-frequency trading, and other scenarios...

At the same time, the high reliability and security features of the Saisi synchronous clock perfectly adapt to the resource dynamic scheduling requirements of the Volta Cloud Yangtze River Delta Computing Power Center. The product adopts satellite sources, power redundancy design, and in the event of external signal interruption, the built-in crystal oscillator combined with FPGA timing algorithm can maintain a 12-hour timing error of ≤1μs/h, ensuring business continuity in extreme scenarios.

3. The logic of digital world evolution, the synergy of computing power, algorithms and clocks

This cooperation between Saisi and Volta Engine is not only a new benchmark case for time synchronization technology empowering new infrastructure, but also reveals that in the era of digital economy, the evolution of infrastructure must be a "trinity" synergy of computing power, algorithms and clocks. When AI large models surpass human cognitive boundaries with trillions of parameters, it is precisely these "invisible time gears" that are supporting the precise operation of the digital world at the bottom level.

Saisi has been deeply engaged in the field of clock synchronization for over a decade. It has established an industrial chain centered around "time source - timing end - usage end - time-frequency chips", gradually building a product system with its own professional characteristics that can serve multiple industry scenarios. This system covers "core components (chips, crystals, atomic clocks) - clock systems (NTP/PTP time synchronization servers, time synchronization devices, satellite intelligent distribution systems, timing security protection devices, time-frequency testers)" and other links. It has formed the R&D and design capability to provide comprehensive time-frequency solutions for customers.

In the future, Saisi will continue to be oriented towards providing high-precision time and frequency benchmarks for thousands of industries in society, driven by technological innovation, shaping core competitiveness for the future, and efficiently empowering the development of digitalized society.
