Poster: A Unified Offload Framework for Host-CSD Architectures: Design, Simulation, and Evaluation

Abstract

To overcome data movement bottlenecks, we propose a unified host and device interaction architecture for computational storage. Our framework facilitates data offloading through a host dispatch engine and a device admission controller. Evaluated using a storage simulator across vector and genomic datasets, our prototype demonstrates substantial speedups for tasks with high data reduction ratios. However, evaluation reveals performance degradation in scenarios with heavy return data, highlighting the critical limitations of static offloading. These findings validate the necessity of developing dynamic offloading strategies for future architectures.
