Abstract
The paper presents a vision and roadmap for achieving efficient and green Large Language Models (LLMs) for Software Engineering (LLM4SE). It begins by highlighting the significance of LLM4SE and the need for efficient and green solutions.
Efficient LLM4SE: The paper discusses the challenges of the computationally-intensive and time-consuming nature of training and operating LLMs, which often requires substantial computational resources and incurs high costs. This limits the accessibility of LLM4SE solutions to the broader software engineering community, including startups and individual developers. The paper emphasizes the need for efficient LLM4SE solutions to address these challenges.
Green LLM4SE: The paper also addresses the high energy consumption and carbon emissions associated with training and running LLMs, which contribute to climate change and environmental degradation. It underscores the importance of developing green LLM4SE solutions to mitigate these negative impacts.
Synergy between Efficient and Green LLM4SE: The paper suggests that efficient and green LLM4SE solutions are closely related, and achieving one can lead to the other. However, they are not identical, and the paper advocates for the synergy of efficient and green LLM4SE solutions to achieve the best of both worlds.
Vision for Efficient and Green LLM4SE: The paper outlines a vision for the future of efficient and green LLM4SE from the perspectives of industry, individual practitioners, and society. For industry, it envisions the development of low-cost and low-latency software engineering tools that are more accessible to companies of all sizes. For individual practitioners, it foresees the emergence of private, personalized, trusted, and collaborative software engineering assistants. For society, it highlights the potential of efficient and green LLM4SE to foster better environmental sustainability in the software industry.
Roadmap for Achieving Efficient and Green LLM4SE: The paper proposes a roadmap for future research, outlining specific research paths and potential solutions, including:
Establishing a comprehensive benchmark to evaluate the efficiency and greenness of LLM4SE solutions.
Developing more efficient training methods for LLMs, such as data and model parallelism, pipeline parallelism, and better optimizers.
Exploring novel compression techniques, including quantization and pruning, to further optimize the efficiency of LLMs.
Investigating improved inference acceleration methods, such as cascade inference strategies and non-autoregressive decoding.
Optimizing the programs built for LLM inference to take advantage of specific hardware features and applying code optimization techniques to improve the efficiency and greenness of the generated code.
The paper aims to inspire the research community to contribute to the LLM4SE research journey, with the ultimate goal of establishing efficient and green LLM4SE as a central element in the future of software engineering.
Stats
The paper does not provide specific metrics or figures to support the key logics. However, it references several studies that quantify the computational and environmental costs of training and running LLMs, such as:
The training of OpenAI's GPT-3 cost over $4 million.
The training of LLaMA consumes 2,638,000 kilowatt-hours of electricity and emits 1,015 tons of carbon dioxide.
Each ChatGPT inference consumes 2.9 watt-hours of electricity, about ten times the 0.3 Wh consumption of a Google search.
LLM-generated code can lag behind human-written code in terms of execution time, memory usage, and energy consumption.
