I am pleased to annouce the Jcluster Toolkit (Ver 1.0) releases, you can freely download it from the website below.

The toolkit is a high performance Java parallel environment, implemented in pure java. It provides you the popular PVM-like and MPI-like message-passing interface, automatic task load balance across large-scale heterogeneous cluster and high performance, reliable multithreaded communications using UDP protocol.

In the version 1.0, Object passing interface is added into PVM-like and MPI-like message passing interface, and provide very convenient deployment -- the classes of user application only need to be deployed at one node in a large-scale cluster.
