Scientists have developed a universal accelerator that can speed up virtually any kind of computer simulation, a ubiquitous research tool across science and industry. This breakthrough technology, co-developed by Rémi Dingreville of Sandia National Laboratories and Vivek Oommen of Brown University, uses machine learning to sniff out mathematical shortcuts through programs, propelling scientists to faster insights about complex problems.
The accelerator has been shown to speed up simulations 16 times faster than normal, with the potential to generalize its approach to different systems, leading to more efficient and sustainable technologies. This innovation could have a significant impact on various fields of science, including materials science, climate change research, self-driving vehicle navigation, and hardware acceleration. The research was funded by Sandia’s Laboratory Directed Research and Development program and supported by the Center for Integrated Nanotechnologies and Brown’s Center for Computation and Visualization.
Accelerating Scientific Discovery: A Universal Simulator for Modern Science
The pursuit of scientific knowledge often relies on computer simulations to model complex phenomena. However, these simulations can be time-consuming and computationally expensive. Recently, a team of researchers from Sandia National Laboratories and Brown University has developed a universal accelerator that can speed up virtually any kind of simulation, revolutionizing the way scientists approach research.
Democratizing Fast Science
The new simulator, powered by machine learning algorithms, can accelerate simulations across various fields of science, including materials science, climate change research, self-driving vehicle navigation, and hardware acceleration. This democratization of fast science has the potential to lead to more efficient and sustainable technologies. According to Rémi Dingreville, a scientist at Sandia National Laboratories, “From a user standpoint, there’s no difference between running your simulation tool or running this accelerated simulation tool. It gives you exactly the same predictions. The difference is how much time it takes to get those results.”
The team’s research, published in the journal npj Computational Materials, demonstrates the simulator’s capabilities by accelerating a materials science simulation 16 times faster than normal. This achievement has far-reaching implications, as it can be applied to various domains, including energy, biotechnology, and environmental science.
Speedier Simulations Enable New Research Opportunities
The simulation accelerator not only saves time and money for routine research but also removes obstacles to studying phenomena that normally can’t be simulated. For instance, modeling an event that unfolds slowly, like glacial melting, becomes feasible with the accelerated simulator. According to Dingreville, “The current state of the art is that you have to use these direct numerical solvers. Even though they are accurate, they’re slow.” The team envisions this research as the genesis of a modern, common way for scientists to zip through normally sluggish simulations.
A New Era in Scientific Research
The universal simulator has the potential to fundamentally rethink how researchers design and use simulations. By integrating traditional numerical methods with artificial intelligence, scientists can tackle complex problems more efficiently. As Vivek Oommen, first author on the paper, notes, “I’m deeply fascinated by the challenges and potentials of integrating traditional numerical methods with artificial intelligence to solve complex problems in materials science.” The team’s work is a call to action for researchers to explore new possibilities enabled by this technology.
Future Directions
The researchers are eager to see their methodologies applied to other challenging problems across various domains. Dingreville hopes to apply the simulator to geoscience, while Oommen looks forward to exploring its potential in energy, biotechnology, and environmental science. As the scientific community begins to harness the power of this universal accelerator, it is likely that new breakthroughs will emerge, driving progress in our understanding of complex phenomena and the world around us.
