Memory and I/O intensive applications always use a huge amount of memory and the performance decreases quickly when memory pressure arises. With the development of high performance network and widely used in cluster, the latency of remote memory access is much less than that of disk operation. In this paper, we present an approach to let the VM (Virtual Machine) use cluster-wide free memory, which can overcome the limitation of physical memory by exploiting low-latency access to the memory of other nodes in cluster. This approach can reduce the execution time for memory and I/O intensive applications significantly by utilizing cluster-wide memory and increase the whole cluster utilization.
