A Worker Implementation on Windows OS for User-PC Computing System

Previously, we have proposed and implemented the User-PC computing (UPC) system as a highly parallel computing platform using idling CPU cycles in members' personal computers (PCs) of the same organization such as a laboratory in a university. This implementation for both the UPC master and the UPC worker covers only Linux OS. However, currently a lot of PCs adopt Windows OS. In this paper, we present an implementation of the UPC worker for Windows OS based on the implementation for Linux OS. During the implementation, we realize the CPU usage limitation and the automatic start-up of the worker program which can reduce loads for PC owner, aside from basic functions of master communications and job executions. Through evaluations, we conclude that the CPU usage rate does not exceed the given limitation except for starting time, and the job execution time on Windows is about twice the use of that on Linux.
