This paper introduces the application of IP multicasting for enhancing of software-only DSM systems and, at the same time, simplification of the programming model by offering a simple memory consistency model. The described algorithm is the foundation of a runtime system implemented as filesystems for the Windows NT and FreeBSD operating systems.
