Solving the GPU Utilization Crisis
One of the most compelling demonstrations of our innovation-meets-partnership approach came from Matthias Loipersberger, Product Manager at Fujitsu Research of America, who presented our AI Computing Broker technology. Despite explosive growth in AI infrastructure spending – projected to reach $100 billion by 2027 – peak GPU utilization remains below 70% across enterprises.
Our AI Computing Broker represents a fundamental breakthrough through runtime-aware GPU allocation. “It basically monitors your AI framework and then allocates the GPU on a as needed basis,” Loipersberger explained. The technology dynamically hands over GPU resources between jobs, ensuring maximum efficiency while maintaining full memory access for active programs.
The impact is transformative: overall GPU efficiency increases while time to completion decreases. This innovation exemplifies our approach to solving real enterprise challenges through advanced technology, while the solution's compatibility with existing frameworks like PyTorch and TensorFlow demonstrates our commitment to practical, deployable solutions.
Accelerating Materials Discovery Through AI
Yuto Iwasaki, Researcher from our Computing Laboratory in Japan, showcased how the convergence of AI and high-performance computing is revolutionizing materials science. “By using AI, specifically neural network potentials, we can make simulations up to 100 or 10,000 times faster,” Iwasaki explained, describing how this acceleration dramatically reduces product development cycles.
The practical applications are immediately relevant to enterprise customers. Iwasaki presented a case study involving polymer electrolyte membranes for fuel cells, demonstrating simulations of systems containing 20,000 atoms. The scalability means that we can evaluate many helpful materials by just increasing computing resources, opening new possibilities for rapid materials discovery and optimization.
