This document defines the API of mpiJava, a Java language binding for MPI 1.1. The document is not a standalone specification of the behaviour of MPI--it is meant to be read in conjunction with the MPI standard document . Subsections are laid out in the same way as in the standard document, to allow cross-referencing. Where the mpiJava binding makes no significant change to a particular section of the standard document, we will just note here that there are no special issues for the Java binding. This does not mean that the corresponding section of the standard is irrelevant to the Java binding--it may mean it is 100% relevant! Where practical the API is modelled on the MPI C++ interface defined in the MPI standard version 2.0 . Changes to the mpiJava 1.1 interface: -The MPI.OBJECT basic type has been added. –The interface for MPI.Buffer_detach has been corrected. – The API of User_funcion has been changed. – Attributes cached in communicators are now assumed to have integer values. Attr_put and Attr_delete have been removed. –The interface to Cartcomm.dimsCreate has been corrected. –Errorhandler_set, Errorhandler_get have changed from static members of MPI to instance methods on Comm. –The method Is_null has been added to class Comm. –The Initialization method MPI.Init now returns the command line arguments set by MPI. –MPI exception classes are now specified to be subclasses of MPIException rather than I0Exception. Methods are now declared to throw MPIException (see section 8). The current API is viewed as an interim measure. Further significant changes are likely to result from the efforts of the Message-passing working group of the Java Grande Forum.
