MURaM scientific model deployed asynchronous IO blog published on Medium

Haiying Xu recently wrote a blog titled “Asynchronous I/O in Large-Scale Time-Series Geoscience Simulations” on Medium.com. The blog primarily experimented the ADIOS2 SST Input/Output (I/O) in the MURaM scientific simulation project to enhance performance. SST I/O uses RDMA or WAN communication to stream data asynchronously. It achieved better performance compared to existing MPI-I/O and also facilitated easy conversion of data to C/Fortran order, as well as the ability to rearrange or compress data without reducing performance. This asynchronous I/O approach can significantly improve the efficiency and scalability of large-scale simulations, demonstrating a promising advance in scientific computing.
