We propose a novel cooperative caching system that addresses two problems of existing systems: lack of utilization of high-throughput, low-latency remote direct memory access (RDMA) and low scalability against concentrated request for a particular cache block. The proposed system uses only RDMA to look up a block location in cache directories distributed to servers and transfer a block from another node, reducing access times to a cache block. In addition, to provide more robust scalability, nodes are divided into groups and managed semi-independently, so that access concentration on a particular node is mitigated. We are going to run over 10,000 processes on the K computer for evaluation and present experimental results on the poster. To our knowledge, this will be the first study that investigates performance of cooperative caching with over 1,000 processes.
