In this study, we have made a new model and mechanism for distributed resource management in which there are fault-tolerance, efficiency, scalability, and migration-ability and we have developed an implementation of the model and the mechanism. In the research and development of the SSS-PC operating system, we had proposed a methodology to make one virtualized UNIX domain over multiple PC machines, and invented a scalable and migratable process mechanism. This study would lead the SSS-PCs research and development to the next stage. The following was achieved by the end of fiscal year 2006. The arbitrary pieces of UNIX domains could be established in one SSS-PC system over multiple PC machines. In addition, the fault-tolerant protocol stack communicated with one other party as three TCP protocol stacks cooperated in the SSS-PC system was developed. The fault-tolerant file server system using this protocol stack was experimentally implemented in the first half of fiscal year 2007. One file server program was redundantly executed with three PC machines, and the program used the fault-tolerant protocol stack to communicate external client terminals. In this situation, it was proven to keep providing service even if one of PC machines where the file server program was running broke down. However, it was clarified that the overlap of the name space in redundant execution became a problem through this experimental implementation. For the fundamental solution of the problem, it was concluded that it was necessary to treat each program of redundant execution as independent existence on the name space. Therefore, the execution method was switched to the method to achieve each program execution of redundant execution respectively on another virtualized UNIX domain, and virtualization mechanisms for UNIX domain was enhanced in the latter half of fiscal year 2007.

在这项研究中，我们建立了一个新的模型和机制，用于分布式资源管理，其中具有容错，效率，可伸缩性和迁移性，我们已经开发了该模型和机制的实现。在SSS-PC操作系统的研究和开发中，我们提出了一种方法，以在多个PC机器上制作一个虚拟化的Unix域，并发明了可扩展且可迁移的过程机制。这项研究将使SSS-PCS研发进入下一阶段。以下是在2006财政年度结束之前实现的。任意的UNIX域可以在一个SSS-PC系统中建立在多台PC机器上。此外，由于开发了SSS-PC系统中配合的三个TCP协议堆栈，与另一方交流了易于故障的协议堆栈。使用此协议堆栈的容忍失误的文件服务器系统在2007财政年度的上半年实验实现。使用三台PC机器裁员执行了一个文件服务器程序，并且该程序使用容忍度耐受的协议堆栈来通信外部客户端终端。在这种情况下，即使文件服务器程序正在运行的PC机器中的一台PC机器也破裂，也可以继续提供服务。但是，可以澄清的是，通过这种实验实现，冗余执行中名称空间的重叠成为一个问题。对于问题的基本解决方案，可以得出结论，有必要将每个冗余执行程序视为名称空间的独立存在。因此，将执行方法切换到该方法，以分别在另一个虚拟化UNIX域上分别实现冗余执行的每个程序执行，并且在2007财年后半段，UNIX域的虚拟化机制得到了增强。
