Method Detail

starPready

public static boolean starPready()

Returns true if starPstart has been called sucessfully. MATLAB*P integration method.

starPstart

public static void starPstart(int rank,
                              int size,
                              java.lang.String[] hosts)

Builds the Java socket network used by MPI. MATLAB*P integration method.

init

public static void init()

Initialize the MPI execution environment. MPI API method.

fnlz

public static void fnlz()

Terminate the MPI execution environment. MPI API method; replaces finalize, which cannot be used due to a naming clash.

main

public static void main(java.lang.String[] argv)
