-Java applications may use MPI for inter-process communication, in conjunction with OpenMPI. Read more [here][a]. This functionality is currently not supported on Anselm cluster. In case you require the java interface to MPI, contact [cluster support][b].

 ## Java With OpenMPI
 
-Because there is an increasing interest in using Java for HPC. Also, MPI can benefit from Java because its widespread use makes it likely to find new uses beyond traditional HPC applications.

-The Java bindings are integrated into OpenMPI starting from the v1.7 series. Beginning with the v2.0 series, the Java bindings include coverage of MPI-3.1.
