    Neko is a portable framework for high-order spectral element-based simulations, focusing primarily on incompressible and compressible fluid flows. Written using a modern object-oriented approach, the framework supports a wide range of hardware backends, including general-purpose processors, accelerators, and vector processors. Neko has demonstrated excellent performance and scalability across various hardware architectures and was nominated as…

    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…

    I’m Manuel Münsch, one of the senior researchers within CEEC, working at the Institute of Fluid Mechanics at FAU. I did my master’s in mechanical engineering with a specialization in aerospace engineering and was already enthusiastic about fluid dynamics. I was quite sure that I wouldn’t spend my working life mainly with computers, though.
