Abstract:
    Computational methods are revolutionizing the landscape of astrophysical simulations, necessitating the development of well- optimized systems to fully harness the capability of modern computing devices. In this presentation, we will delve into KRATOS, a state-of- the-art high-performance heterogeneous simulation system developed by the speaker. KRATOS is distinguished by its meticulously crafted one- sided coupling mechanism that integrates seamlessly with geometrical and physical modules, culminating in a sophisticated infrastructure that offers unparalleled versatility and flexibility. The system is equipped with a lightweight abstraction layer, facilitating its operation across various hardware and software platforms, including those powered by GPUs. We will explore the applications of KRATOS in astrophysical simulations and touch upon its potential for other research domains, showcasing its adaptability and the breadth of its utility.
