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.
