DescriptionThe recent advancement of technology in both software and hardware enables us to revisit the design of the composable architecture in the system design. The composable system design provides capability to serve a variety of workloads. The system offers a dynamic co-design platform that allows experiments and measurements. This speeds up the system design and software evolution. It also decouples the lifecycles of components. The design consideration includes adopting available technology with the understanding of application characteristics. The design has the potential to be the infrastructure of cloud computing and the HPC architecture.
