Neuromorphic Hardware Offers Energy Efficiency in Finite Element Method Applications

Sandia National Laboratories researchers have demonstrated the potential of neuromorphic computing. It provides a greater energy savings alternative to traditional computational techniques used in finite element methods (FEM). Bradley Theilman and James B. (Brad) Aimone guided the team through this innovative research. They detailed their use case in Nature Machine Intelligence, demonstrating the advantages of deploying neuromorphic hardware for high-order mathematical modeling.

Theilman notes that their estimates indicate executing FEM on neuromorphic systems would provide a modest energy benefit. This benefit is in sharp relief to legacy systems. He further summed up just how important this development is. Consider how incredible it is that the human brain operates on 10 watts of power while deftly solving comparable high-dimensional, messy, and dynamical conundrums.

The Sandia team’s research revolved around translating FEM into a motor cortex model, which was implemented on Intel’s Loihi 2 neuromorphic hardware. This system, designed to mimic the brain’s processes, can adeptly solve partial differential equations, showcasing its potential for applications that require real-time processing and decision-making.

Advancements in Neuromorphic Computing

Neuromorphic computing is about engineering a new class of systems that emulate brain-scale processing power. These systems have largely been optimized with an eye towards applications like real-time processing of sensor data. Theilman and Aimone’s research unlocks a larger world of possibilities for neuromorphic computing. This is an exciting finding as it broadens our understanding of its positive effects within the field of computer science.

Aimone, who has a background in neuroscience, stated, “There’s no reason to assume you can’t do something in neuromorphic computing.” This optimism invites us to dig deeper into a broader set of mathematical challenges that stand to gain from these new paradigms.

This Sandia team recently made public some of their surprising discoveries on FEM. More significantly, they applied the Monte Carlo method for solving differential equations with the neuromorphic hardware, expanding the range of possible applications. Aimone remarked on the advancements made in artificial intelligence, noting, “We have made tremendous advances in AI, but people are building power plants.” This statement illustrates the importance of researching energy-efficient computational approaches.

The Significance of Finite Element Methods

As a branch of numerical analysis, finite element methods have found extensive application across engineering and physics in analyzing complex structures and systems. Those traditional computational techniques have been further optimized for the standard hardware, but still command an extensive energy footprint. According to the Sandia team’s research, systems such as Loihi 2 can significantly reduce the energy required. Beyond advancing research, they hold great promise for increasing efficiency in computation.

Theilman’s comparison of the numerical tables forming the basis of their models with the matrices typically used in a FEM. He noted, “It’s a complex problem. The brain is controlling muscles in response to real-time information to make contact with the ball.” This analogy beautifully illustrates the complexities and challenges of real-time, on-the-ground, tactical problem-solving. It is powerful in highlighting how neuromorphic systems can perform these tasks with amazing efficiency.

As Aimone explained, Loihi 2 is uniquely positioned to tackle these kinds of issues. This is largely due to its design, which allows the neural network to process information in sophisticated ways that parallel how the human brain functions. This ability makes neuromorphic computing an exciting new option for addressing problems across all areas of science.

Future Implications

The impacts of this research reaches far beyond energy efficiency. As neuromorphic computing technologies continue to develop, they’ll begin to redefine how computation is done in every industry. The integration of brain-like processing capabilities could lead to advancements in numerous applications, including robotics, artificial intelligence, and real-time data analysis.

The Sandia team’s findings further confirm that pursuing alternative computational paradigms can uncover solutions that once seemed impossible. As Aimone stated, “It’s worth looking deeply at any kind of mathematical problem.” Such a method of exploration greatly widens the scope of what is possible in on-demand, computationally assisted science. It further provides a tremendous spark to innovation in energy-efficient technologies.
