Abstract

This paper presents and evaluates a parallel Java implementation of the Finite-Difference Time-Domain (FDTD) method, which is a widely used numerical technique in computational electrodynamics. The Java version is parallelized using MPJ Express - a thread-safe messaging library. MPJ Express provides a full implementation of the mpiJava 1.2 API specification. This specification defines a MPI-like binding for the Java language. This paper describes our experiences of implementing the Java version of the FDTD method. Towards the end of this paper, we evaluate and compare the performance of the Java version against its C counterpart on a 32 processing core Linux cluster of eight compute nodes.
