Efficient replicated method invocation in Java
Jason Maassen, Thilo Kielmann, Henri E. Bal · 2000
We describe a new approach to object replication in Java, aimed at improving the performance of parallel programs.Our programming model allows the programmer to define groups of objects that can be replicated and update d as a whole, using totally-ordered broadcast to send update methods to all machines containing a copy.The model has been implemented in the Manta high-performance Java system.Performance measurements on a Myrinet cluster show that the replication mechanism is efficient (e.g., updating 16 replicas of a simple object takes 68 microseconds, only slightly longer than the Manta RMI latency).Example applications that use object replication perform as fast as manually optimized versions based on RMI.
