WIPL-D (WIre PLate Dielectric) has become an increasingly popular Method of Moments (MoM) code used in computational electromagnetics (CEM) modeling. WIPL-D was chosen for parallelization under the Common High Performance Computing Software Support Initiative (CHSSI) program of the High Performance Computing Modernization Office (HPCMO). Hence, the new code was given the name WIPL-DP, where \"P\" stands for Parallelized. Any computer code chosen for parallelization under the CHSSI program must undergo four rigorous phases of testing: Software Acceptance Test, Alpha Test (AT), Beta Test (BT), and Initial Operational Test and Evaluation (IOT&E). WIPL-DP is currently undergoing those tests, with the Alpha Test recently completed and reported on in this effort. The Beta Test and the IOT&E are to be completed by 30 September 2004. WIPL-DP is a parallelized C/C++ version of the original FORTRAN 77 WIPL-D code. During the Alpha Test period, WIPL-DP was successfully parallelized for frequency. It also received optimal performance rating for the following Critical Technical Parameters (CTPs): scalability; portability; and correctness, stability, and accuracy. The chosen test case for the Alpha Test was a modified version of the “Human Head Adjacent to a Cellular Phone” (DEMO-531) problem available under the tutorial sub-directory in the PC version of the WIPL-D software. The Alpha Test was performed on two distinct High Performance Computing (HPC) platforms, Tempest and Huinalu, both at the Maui HPC Center.
