Abstract: Computer resource sharing provides an effective way to solve the imbalance of computer resource distribution and computing power demand, it also provides a way to solve the computer resource waste in the network. However, the traditional computer resource sharing system generally adopts the way of task allocation, users can hardly use the shared resource in a direct way. In addition, the task allocation and scheduling are managed by the central node. Once the central node is damaged, the resource sharing system will not function properly. In view of the above problems, this paper proposes a distributed resource sharing model. By delivering a private chain to bulid the underlying structure of the resource sharing model, we can directly provide users shared resources in P2P way. This paper analyzes the key implementation mechanism of resource sharing model, and builds a distributed computing network to truly realize computer resource sharing. We conduct experiments on CPU and memory utilization of the resource sharing model during normal operation and the results validate the effectiveness of the proposed resource sharing model in improving resource utilization and computing ability.
