In this paper we explore the use or remote main memory for paging. We describe the design, implementation and evaluation of a pager that uses main memory of remote workstations as a faster-than-disk paging device. Our pager has been implemented as a block device driver linked to the DEC/OSF1 operating system, without any modifications to the kernel code. 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 conclude that the increasing use of fast local area networks will improve the performance of remote memory paging even more.
