| Abstract |
Traditional operating systems use magnetic disks as paging devices, even though the cost of a disk transfer measured in processor cycles continues to increase. In this paper we explore the use of remote main memory for paging. We describe the design, implementation and evaluation of a pager that uses main memory of remote workstations in a workstation cluster as a faster-than-disk paging device and provides reliability in case of single workstation failures. Our pager has been implemented as a block device driver linked to the DEC OSF/1 operating system, without any modifications to the kernel code and effectively turns the cluster's main memory into a global cache for its swap partitions. Using several test applications we measure the performance of remote memory paging over an Ethernet interconnection network and find it to be faster than traditional disk paging. We evaluate the performance of various reliability policies and prove their feasibility even over low bandwidth networks, like Ethernet. We use our system over simulated high bandwidth networks and evaluate its performance. We conclude that the benefits of reliable remote memory paging in workstation clusters are significant today and will probably increase in the near future.
