  In Hama BSP computing framework, the Partition function is used for obtaining scalability
of a Bulk Synchronous Parallel processing, and determining how to distribute the slices of
input data among BSP processors. Unlike Map/Reduce data processing model, many scientific
algorithms based on Message-Passing Bulk Synchronous Parallel model often requires that a
processor obtain “nearby or related” data from other processors in order to complete the
computation. In this case, you can create your own Partition function for determining processor
inter-communication and how to distribute the data.
