In this work, Internet Supercomputing methodology is introduced and the concept is materialized for large-scale finite element analysis. The primary resources of Internet Supercomputing are numerous idling PCs connected by Internet with no regards to their locations. Under the above concept, virtual supercomputing system InterSup I is constructed and tested. To establish the InterSup I system, 64 PC nodes, which are located in several places and connected by Internet, are conscripted, and the finite element code, IPSAP(Internet Parallel Structural Analysis Program) based on parallel multifrontal solver is developed for solving structural analysis problems. And mesh-partitioner based on graph-partitioning algorithms with WVEM(Weight Vertex and Edge Method) proposed in this work also developed. By the establish InterSup I system, analysis of finite element structural model having around 10 million DOFs are solved and the elapse time is 28,194 sec. From these results, it is confirmed that the proposed Internet Supercomputing methodology has a great promise and potential as a next-generation.
