    WAKASHI/C (centralized server version) is a sub‐system at the base level of the “Shusse Uo” project. It provided the C programmer with the basic functions to manipulate the distributed shared persistent data and the distributed shared volatile data. In WAKASHI/C, the virtual memory scheme and the distributed shared memory scheme are combined to realize the distributed shared persistent heap and the distributed and shared volatile heap, for the efficient handling of multimedia data. This paper discusses the realization of WAKASHI/C corresponding to the distributed computing environment. To evaluate the performance for the manipulation of the multimedia database, the extended object operation benchmark is proposed, and the execution performance of WAKASHI/C is evaluated.
