Definition
While Java offers both a means for programming threads on a shared-memory parallel machine and a means for programming remote method invocations in a wide-area distributed memory environment, it lacks support for NUMA-architectures or clusters, that is, architectures where locality matters because of nonuniform access times. Java also lacks support for a more data-parallel programming style.
JavaParty fills this gap by providing language extensions that add both remote objects and collectively replicated objects. The former allow the programmer to express knowledge about the locality of both the application’s objects and threads in an abstract way, that is, without requiring code for low-level object placement, for explicit replication and (cache) coherency, or for low-level details of explicit message passing. The latter provide a means for working elegantly on all objects of an irregular data structure in parallel.
The beauty of JavaParty is twofold. First, the flavor of...
