Abstract Physical memory capacity has increased owing to large-scale integration. In addition, memory footprints have increased in size, as multiple programs are executed on a single computer. Many operating systems manage physical memory by paging a 4 KB page. Therefore, the number of entries in the virtual address translation table for virtual to physical increases along with the size of the memory footprints. This cause a decrease in the translation lookaside buffer (TLB) hit ratio, resulting in the performance degradation of the application. To address this problem, we propose the implementation of physical memory management with two page sizes: 4 KB and 4 MB. This allows us to expand range of addresses to be translated by a single TLB entry, thereby improving the TLB hit rate. This paper describes the design and implementation of the physical memory management mechanism that manages physical memory using two page sizes on The ENduring operating system for Distributed EnviRonment (Tender OS). Our results showed that when the page size is 4 MB, the processing time of the memory allocation can be reduced by as much as approximately 99.7%, and the processing time for process creation can be reduced by as much as approximately 51%, and the processing time of the memory operation could be reduced by as much as 91.9%.

Abstract To handle information leaks caused by administrative errors or mishandling, a function for tracing the diffusion of classified information using a virtual machine monitor (VMM) was proposed. However, the proposed function has not been investigated in cases in which virtual machines (VMs) allocated by multiple virtual central processing units (vCPUs) are to be monitored. In addition, cases in which multiple VMs are monitored have not been examined. In this study, we describe the support of multiple VMs for the proposed VMM-based tracing function. We also show how to deal with VMs allocated by multiple vCPUs. Furthermore, we report the evaluation results from assessing the traceability of the improved proposed method and its overhead for classified information when a VM with multiple vCPUs is monitored.
