Distributed EZ [string processing language]

EZ is a system that integrates traditional operating systems and programming languages into a very-high-level persistent string processing language. The authors describe the design and initial implementation of a distributed memory manager that distributes EZ´s virtual address space transparently among a network of homogeneous computers. The design adapts the techniques used in recent implementation of shared virtual memory for use in EZ´s persistent environment. Unlike most implementations of shared virtual memory, control information is distributed and migrates. This memory manager works in concert with a distributed mark-and-sweep garbage collector, which is also concurrent and real-time. This collector trades time for space and minimal disruption of mutators, which reduces communication costs
