Java classes for MPI

All MPI classes, constants, and methods are declared within the scope of an MPI package. Thus, by import the MPI package or using the MPI.xxx prefix, we can reference the MPI Java wrapper. The classes of the MPI package are those classes corresponding to objects implicitly used by MPI. An abbreviated definition of the MPI package and its member classes is as follows:

package MPI;

public class MPI;
public class Comm;
public class Group;
public class Datatype;
public class Op;
public class Status;
public class Request;
public class Errhandler;
