Abstract
Performance optimization is achieved by clarifying cache usage characteristics of each application from usage conditions of physical resources (caches) in real time and automatically controlling the cache usage amount of each application. Thus, a system includes a main memory to and from which data is written and read, a level 3 cache memory which can be accessed faster than the main memory, a CPU core configured to execute processing by performing write and read to and from the memory and the cache, a usage amount measurement unit configured to measure a usage condition of a cache of each virtual machine (to) executed by the CPU core, an allocation amount calculation unit configured to calculate cache capacity to be allocated to each virtual machine (to) from the usage condition, and a control unit configured to allocate the cache capacity to each virtual machine (to).
