This paper introduces a system, called ubiquitous multi-processor (UMP) system, which constructs a dataflow network dynamically by connecting function-specific execution modules. We developed a general-purpose execution module (GP-PE) which performs an equivalent function to SS-PE by downloading the software library to improve the efficiency of development and reconfigure the function dynamically. This paper shows overhead time is 200 ms caused by network communication among PEs using 1000 Base-T, on decentralized network where a client module, management modules, and calculation modules including GP-PE are deployed, comparing it with the system performance on a single PC. The experimental result presents the adaptability of GP-PE to UMP system in general use. Moreover, the ratio of the overhead time of the library to downloading time for general using is clarified. It becomes useful parameter to decide method of downloading DPL.
