Typical engineering design offices are equipped with several PC computers with different processor power, available memory and disk capacity. The computers are usually connected with fast Ethernet. The computing performance is relatively high with respect to the demands of design process involving CAD, structural analysis, etc. This makes the offices well equipped for high performance computing provided relevant parallel software is available. Although there may be different combinations of hardware and software forming a parallel computing environment it can be shown that the results (computational time, speedup, efficiency) achieved on such cluster are competitive to results obtained on special parallel computers, as IBM SP2, SGI Origin, etc. It is important to realize that from engineering point of view the scalability of the algorithm is not the only criterion to judge the efficiency of parallel application. In many case, the ability to analyze extremely large problems not solvable on individual machines is of primary interest.
