Locality optimization in JavaParty by means of static type analysis

On clusters and DMPs, locality of objects and threads and hence avoidance o f network communication, are crucial for the application performance. We sh ow that-in certain situations-an extension of known type inference mechanis ms can be used to compute placement decisions that improve locality of thre ads and objects and hence reduce the application execution times, In additi on to this general contribution, the paper specifically addresses the probl ems that are caused by the distributed Java environment, Since the JVM and the bytecode format are assumed to be fixed, the optimization is done as so urce-to-source transformation.
