DSVM6K: distributed shared virtual memory on the RISC System/6000

The authors describe DSVM6K, an implementation of distributed shared virtual memory (DSVM) in AIX v3 on the IBM RISC (reduced instruction set computer) System/6000 workstation. The design and implementation exploit the high-speed fiber links and low-overhead link protocols on the RISC System/6000 workstation. The results demonstrate that technology like this is required for a high-performance DSVM system. DSVM6K achieves the highest performance of any DSVM system reported in the literature. Descriptions of the overall design, programming interfaces, performance measurement data, and application results are presented.<>
