| Research Abstract |
Program slicing is one of the important means to understand existing software. Inoue et al. developed an efficient method to get program slice, and proposed accumulative versioning file. Based on his proposal of a systematic methodology to develop large-scale concurrent software, Cheng et al. designed and partially implemented a support environment for developing such software.
In order to support reconstruction of existing software, Ushijima et al. proposed a method to make effective use of design patterns related to hot spots of the target software, and applied the method to redesign an application software and evaluated the effect of the method.
Torii et al. constructed CAESE (Computer Aided Empirical Software Engineering) environment to support collection and analysis of data needed to quantitatively and qualitatively evaluate adaptability of reconstructed software.
Tokuda et al. made a research and development of software architecture of next generation OS to be adaptable to parallel and distributed systems, multimedia systems, mobile and ubiquitous systems, etc. Fukuda et al. designed an automatic generation method of device drivers as an evolutionary mechanism for OS, and implemented them to experimentally evaluate the method using Free BSD and Linux.
In order to provide a portable compiler which reflects individual architecture of every parallel computer, Yuasa et al. proposed an optimization mechanism based on special characteristics of individual architecture, and investigated how to implement the mechanism.
In order to guarantee service execution time independent of hardware performance, Taniguchi devised a process scheduling method to regulate allocation of processors to the program, implemented and evaluated the method.
