Proteus: a runtime reconfigurable distributed shared memory system
Jyh-Chang Ueng, Ce-Kuen Shieh, W. Liu, Chi‐Chang Lin · 2003
This paper describes a Distributed Shared Memory (DSM) system called Proteus, which aims to support runtime node reconfiguration. To make the system execute efficiently after node reconfiguration and reduce the overhead of reconfiguration, Proteus employs an adaptive workload redistribution strategy to perform workload redistribution as well as an affinity page movement strategy to redistribute memory pages. Furthermore, a forced update technique and a set of scalable synchronization mechanisms are developed to keep memory consistent and to perform a correct synchronization, respectively.
