BSPlib Java Interface for Parallel Scientific Computing Applications

This work presents a Java interface to a native BSPlib library for implementing parallel algorithms in a structured way (as described by the BSP model), using the Java programming language. To compare the created library to existing parallel programming solutions, a typical physics simulation application is created. It employs the parallel conjugate gradient method for solving systems of linear algebraic equations, a common scientific computing algorithm, which is challenging from a parallelization standpoint. Using the results from running the test application, the Java BSPlib interface is compared to various MPI (Message Passing Interface) implementations.
