Java* Bindings for MPI-2 Routines

Intel® MPI Library provides an experimental feature to enable support for Java* MPI applications. Intel MPI Library provides Java bindings for a subset of MPI-2 routines.

You can find all supported MPI routines in the table below. All the classes below belong to the mpi package.

Note

  • For static methods, parameters fully correspond to the ones of C routines.
  • For non-static methods, the object that calls the method corresponds to the OUT parameter of the original C routine.
