mpiJava under WMPI:

To create a release of mpiJava for WMPI the following steps were undertaken:

• Step 1 - Compile the mpiJava JNI C interface into a Win32 Dynamic Link Library (mpiJava.dll).

• Step 2 - Modify the name of the library loaded by the mpiJava interface (MPI.java) to that of the of the newly compiled library.

• Step 3 - Compile the Java MPI interface into class libaries.

• Step 4 - Create a JNI interface to WMPI. This was necessary as under WMPI a master process is first spawned. Its purpose is to first read in a job configuration file and use the information within it to set up and run the actual MPI processes. An idiosyncrasy of WMPI is that all MPI processes must have a file name with the extension .EXE. This led to the need to produce a JNI to WMPI so that the JVM was loaded and the 'main' method of mpiJava Java class started.
