Summary

The current research involves parallel processing of ADPAC (An Advanced Ducted Propfan Analysis Code) on local area and wide area networks formed by combined Unix and Windows/NT environments. ADPAC was originally developed at NASA and Rolls-Royce (formerly, Allison Engine Company) to run on Unix-based system computers ^{[1, 2]}. The results obtained from each workstation are compared and verified by using a CFD test case. Timing evaluation and dynamic load balancing studies are conducted. The dynamic load balancing tools developed at the IUPUI's CFD laboratory are utilized in conjunction with a 500,000 grid points CFD test case to perform this task. All the work involving timing evaluation and dynamic load balancing are done by using a 100Mb switch as the communication network. Special emphasis is given to running the code in heterogeneous workstation environments. In order to evaluate the performance of each workstation in heterogeneous environments, the computational and communication times obtained are analyzed. The speedup and efficiency of each workstation in parallel computation are also compared. The effects of load balancing on the total elapsed time and for achieving balanced load in heterogeneous environments are demonstrated in this document.
