A simulation system for producing equivalent circuits reads data corresponding to a tabular W element format in a storage device, and adds data of the tabular W element format file using interpolation algorithm. According to various embodiments, a write log is maintained including log entries for data transfer requests being served by a respective node of the multiple-node data storage system. At least one auxiliary receiver is connected to function as a receiving unit, which the main receiver controls by controlling means. At least the part of the filler exposed to the surface of the sealing resin includes a crack that extends from an exposed surface of the filler into an inner portion. The processing plan defines a processing tree comprising a subset of the plurality of processing nodes, the processing tree having unidirectional communication from the root to a final level of the tree.
