The Evolving Landscape of AI Accelerators: A Key to Technological Advantage

Artificial intelligence continues to transform industries and redefine national security realms. Keeping one step ahead, knowing the latest and greatest in AI hardware capabilities, is crucial. This is particularly the case with AI accelerators, specialized systems expressly built to power neural networks, deep learning, and machine learning. These accelerators have grown from strength to strength and have been standing loud and proud at the center stage of technological advancements for close to a decade.

Mapping the AI Accelerator’s Progress

The Lincoln Laboratory Supercomputing Center (LLSC) launched an extensive study named Lincoln AI Computing Survey (LAICS, pronounced “lace”) back in 2018. All credit goes to Albert Reuther and his diligent team for spearheading this exhaustive research into the world of AI accelerators. The core aim of LAICS? To evaluate and compare commercially available AI accelerators around the world, strictly based on their peak performance and energy consumption. To date, they have put together six informative papers that paint a comprehensive picture of the constantly shifting AI hardware scene.

Reuther shares how the idea for LAICS took root. Around eight years ago, an influx of research AI accelerators emerged, delineated in papers, and commercial accelerators filled the market. The LLSC team pounced on this opportunity and launched the survey, guiding the design optimization of high-performance computing systems that support thousands of lab researchers.

AI accelerators’ potential extends well outside the box of machine learning. From modelling molecular functions to simulating fluid dynamics, these accelerators have provided the need for speed, accompanied by high efficiency in these computationally intensive tasks. The AI accelerators come in diverse forms, such as CPUs, GPUs, ASICs, FPGAs, and dataflow accelerators. These accelerators cater to various workloads, providing flexibility, and their performance and efficiency are based on their unique designs.

Dynamic Field of AI Accelerators

Together with researchers from Lincoln Laboratory, Reuther’s team explores how AI accelerators assist research and development. The initiation paper analyzed 57 accelerators, while the most recent one expanded to investigating over 120. And although new startups continue to flood the AI accelerator market, new inventions and advancements are abound, keeping the field fresh and exciting.

LAICS doesn’t just scratch the surface. Each paper probes deep into a new facet of the field. Take the 2022 paper for instance, it dove headfirst into performance boosts acquired from tinier, denser transistor designs and lower numerical precision.

The Road Ahead

Reuther plans to keep LAICS up and running, with six new startups already poised to introduce their AI accelerators into the market. He underscores the value of neutral technical advice to facilitate the choice of the right technologies. LAICS has not only informed sponsors and government peers on the AI accelerator landscape but it has also pointed them in the direction of implementi.ai when conducting their search for AI automation solutions.
