Introduction
In the ongoing global race to dominate the artificial intelligence (AI) industry, China’s ambitions to rival American computing giants, particularly NVIDIA, have been significantly impacted by the performance issues and instability of software from leading AI chip manufacturer Huawei. The technological landscape has been further complicated by Washington’s tightening export controls on high-performance silicon chips, which has hindered China’s ability to develop domestic alternatives to NVIDIA’s industry-leading products.
The Role of NVIDIA and the Challenge of Huawei’s Software
NVIDIA’s software platform, CUDA, has been a cornerstone of the company’s success, known for its ease of use and significant acceleration of data processing speeds. This has set a high bar for other companies, including Huawei, which has sought to break NVIDIA’s dominance in the AI chip market by developing alternative software solutions. However, the software developed by Huawei, known as 昇腾异构计算架构CANN, has been criticized for its numerous flaws, particularly in the context of early model training.
Performance Shortcomings and Customer Complaints
A series of internal industry reports indicate that, in the realm of model training, Huawei’s Ascend series chips lag significantly behind NVIDIA’s offerings. This discrepancy is attributed to a variety of factors, including stability issues, slower interchip connections, and the inadequacies of the CANN software. NVIDIA’s software is often cited as a secret sauce that facilitates the development process and accelerates the pace of innovation.
The Struggle for Software Excellence
Despite Huawei’s efforts to develop a robust software ecosystem, the company’s own employees and industry partners have reported difficulties with CANN. The software has been described as difficult to use and unstable, with frequent random errors that are hard to trace back to their source due to insufficient documentation. Skilled developers are often required to delve into the source code to identify and resolve issues, a process that can significantly slow down development timelines.
The Human Element: Huawei’s Customer Support
Huawei has been reported to leverage its extensive workforce, with over 50% of its 207,000 employees engaged in research and development, including field engineers who provide direct support to clients. This approach allows Huawei to offer a level of customer service and technical assistance that is reportedly unmatched by NVIDIA, particularly in resolving issues with its hardware and software.
Addressing Challenges with Technical Support and Community Feedback
To mitigate the impact of these software challenges, Huawei has dispatched teams of engineers to assist clients in transitioning from NVIDIA’s CUDA to their own CANN software. This has included updating training code for clients like Baidu, iFlytek, and Tencent, which have had to adapt to the limitations of the Huawei chips.
Strategic Moves and Future Prospects
In response to the heightened export controls and supply chain disruptions, Huawei has increased the price of its training chips, Ascend 910B, by 20% to 30%. This adjustment, coupled with concerns over the availability of advanced chip manufacturing equipment, particularly from Dutch company ASML, has further strained Huawei’s ability to supply its chips to key clients.
Conclusion
As China continues its quest to establish a robust AI industry capable of competing with global leaders like NVIDIA, the software challenges faced by Huawei have become a significant hurdle. While the company has demonstrated a strong capacity for customer support and technical innovation, the software shortcomings of its Ascend series chips remain a critical area of focus for improvement. The ongoing saga highlights the complexity of the AI landscape and the challenges posed by both technological and geopolitical dynamics in the pursuit of AI dominance.
