SPACE: A Lightweight Collaborative Caching for Clusters

In this paper, the authors introduce Systematic P2P Aided Cache Enhancement or SPACE, a new collaboration scheme among clients in a computer cluster of a high performance computing facility to share their caches with each other. The collaboration is achieved in a distributed manner, and is designed based on peer-to-peer computing model. The objective is to provide a decentralized solution, and a near optimal performance with reasonably low overhead. Simulation results are given to demonstrate the performance of the proposed scheme.
