With rapid growth of WAN infrastructure and development of Grid middleware, it's become realistic and attractive methodology to construct wide-area cluster-of-clusters using commodity PCs to run computation-demanding applications. Many of existing parallel finite element applications have been, however, developed under the assumption of the execution on single cluster, and those applications require frequent synchronization and communication among processes. There have been few FE applications that can exploit the distributed environment. In this study, we classified FE applications into two types, called tightly coupled applications and loosely coupled applications. Then we ported and exectuted prototype applications of each type on two clusters. For each type of applications, we evaluate the computational feasibility of utilizing cluster-of-clusters. It is important to achieve load balance that compensates the differences in hardware performance for tightly coupled applications, and load balance between program modules for loosely coupled applications.
