....well. CCJ implements efficient collective operations with an interface that fits into Java s object oriented framework. An alternative for parallel programming in Java is to use MPI instead of RMI. MPJ [9] proposes MPI language bindings to Java. These bindings merge several earlier proposals [2, 10, 17, 23]. This approach has the advantage that many programmers are familiar with MPI and that MPI supports a richer set of communication styles than RMI, in particular collective communication. However, the current MPJ specification is intended as . initial MPI centric API and as . a first ....

....the flexibility and expressiveness of GMI. A radical alternative for parallel programming in Java is to use a communication mechanism outside Java s object model, like MPIstyle message passing. MPJ [11] proposes MPI language bindings to Java. These bindings merge several earlier proposals [4, 12, 20, 25]. Because MPJ has not been implemented yet, we compare GMI to the slightly older mpiJava system. The MPI approach has the advantage that many programmers are familiar with its API and that MPI supports a richer set of communication styles than RMI, in particular collective communication. Although ....

....definition of a Java Binding for MPI [5] along the lines of the MPI 1.2 C binding has been proposed, and work on an implementation is under way. A commercial effort to develop an MPI framework and parallel support environment for Java has been started recently by MPI Software Technology, Inc. [8]. The approach of binding native libraries to Java has certain limitations. In particular, for security reasons applets downloaded over the network may not load libraries or define native methods. Furthermore, a Java program can only use a native library in a single threaded manner unless that ....

In a perfect world we might execute MyMPJApp by a command like 5 This is a change to the API of mpiJava [2] for example, where the main method is static and the default communicator is a class variable. The approach here (which follows more closely DOGMA [8] or JMPI [5]) seems to t more naturally with RMI, and allows for the possibility of running several MPJ processes as threads in a single JVM, although probably that won t be supported in the initial reference implementation. 8 MPJService MPJService MPJService MPJClient MPJSlave MPJSlave MPJSlave MPJSlave ....
