We present an X10 software package for the solution of the shallow water equations, a set of equations commonly used to simulate tsunami and flooding events. The software uses an actor-oriented approach to obtain a communication scheme that does not rely on central coordination. Instead, each actor only communicates with its neighbors. We evaluated the package via scaling tests on single-place shared memory as well as multi-place distributed memory system configurations, and found it to perform comparably to prior implementations based on C++, OpenMP and MPI.
