    Mixed-precision computing has emerged as a key strategy to improve performance and energy efficiency on current and future high-performance computing (HPC) systems. However, integrating mixed-precision into large, production-level scientific applications remains challenging due to concerns about numerical stability, accuracy, and the complexity of identifying which computations can safely tolerate reduced precision. Our results confirm that…

    My name is Yanxiang Chen, a second-year PhD student at Umeå University in Sweden. With a background in computational mathematics, I went on to do a master’s degree at Trinity College Dublin, where I began to build systematic knowledge in parallel computing. After graduation, I had the opportunity to work at the Supercomputing Center in…
