Foil 17 Some Remarks on Remote Method Invocation RMI

From Java Grande Overview IPPS/SPDP 1999 International Workshop on Java for Parallel and Distributed Computing San Juan Puerto Rico -- April 12 99. by Geoffrey C. Fox


So good news is that RMI has enabled very active distributed computing research and indeed development as in JavaSpaces from Sun
Performance is reasonable but insufficient for some applications
  • It is already good enough to get started and for instance outperforms many (Java) CORBA implementations
Forum suggests (optional) changes in several areas including
  • Serialization -- this is used in Persistent object storage and to transmit objects between different programs in a distributed application -- can be optimized differently for each case
  • Transport Layer -- need to be able to layer RMI interfaces over fast transport mechanisms -- Myrinet, native ATM etc.
