| Outline of Final Research Achievements |
In Tender operating system that is a monolithic kernel, we designed a method that reduces mutual exclusion. We evaluated the method. The evaluation results show that the performance of the proposed method is equal to or more than that of Linux and FreeBSD. In addition, we designed a method that can boot an operating system on each core. The evaluation results of the proposed method found the problem of the method in a machine with NUMA. Thus, we investigated the performance of the method in a machine with NUMA, then showed the design principle in a machine with NUMA.
