Photonic Computing Breakthrough in Germany
Q.ANT has successfully delivered its Native Processing Server (NPS) to the Leibniz Supercomputing Centre (LRZ), marking the first deployment of an analog photonic co-processor in a high-performance computing (HPC) environment. This integration allows LRZ to assess the capabilities of photonic acceleration for artificial intelligence (AI) and simulation tasks, potentially leading to significantly improved performance and energy efficiency.
LRZ, one of Europe’s largest data centers and a leader in supercomputing research, is known for its robust infrastructure that fosters innovative scientific advancements. The collaboration with Q.ANT signifies a shift towards more sustainable computing solutions, leveraging analog precision through light to tackle the challenges associated with scaling AI.
The deployment is considered a major milestone in the move toward energy-efficient computing. Prof. Dr. Dieter Kranzlmüller, Chairman of the Board of Directors at LRZ, emphasized the importance of the collaboration, stating that it will facilitate immediate performance evaluation without extensive modifications to existing systems. He also acknowledged the critical support from the federal and Bavarian governments in enabling this initiative.
Q.ANT’s CEO, Dr. Michael Förtsch, described the project as a historic achievement, highlighting the practical application of photonic processors in HPC. He expressed optimism about integrating photonic computing into mainstream architectures by 2030, emphasizing the crucial role of governmental support in this endeavor.
The photonic processor offers several advantages:
– It consumes up to 90% less power per workload due to the absence of on-chip heat, eliminating the need for costly cooling solutions.
– It allows for up to 100 times greater capacity in data centers by enhancing computational density and speeding up complex operations.
– It maintains close to 100% accuracy in computational operations with 16-bit floating point precision.
The collaboration is part of a broader initiative to explore hybrid digital-analog architectures for future HPC systems, funded by the German Federal Ministry of Research, Technology and Space. By incorporating photonic analog computing, a feature not previously viable, this project aims to set benchmarks in various applications, including climate modeling, real-time medical imaging, and materials simulation for fusion research.
As LRZ initiates the first evaluation phase, the focus will be on testing multiple NPS units with selected benchmark workloads, emphasizing AI inference, computer vision, and physics simulations. Future phases will include enhanced units for deeper evaluations.
The commissioning ceremony, attended by key figures in politics, research, and industry, underscored the project’s significance. Federal Minister Dorothee Bär highlighted it as a valuable example of Germany’s leading-edge technology and innovation, which bolsters the nation’s scientific leadership.
In closing, Markus Blume, Bavarian Minister of Science and the Arts, remarked on the revolutionary potential of computing with light, affirming that this project exemplifies the collaboration between science, industry, and government that propels innovative breakthroughs.
Q.ANT, founded in 2018 and based in Stuttgart, specializes in photonic processing solutions, enabling energy-efficient computing for next-generation AI and HPC applications.
