Abstract: PURPOSE: A memory management device and a method thereof are provided to efficiently and stably use a restricted cache memory resource and to setup a block group between a main memory and a cache memory. CONSTITUTION: A memory group setting unit(151) gives a group ID to each group. A page cache setting unit(152) sets up a plurality of blocks to a page cache. A memory mapping unit(153) maps a block of a virtual memory of each process. A page cache managing unit(154) selects a block of the page cache as the buffer in a data access command process. The page cache managing unit gives the group ID according to a selection sequence of the block.

Abstract: PURPOSE: A memory reuse method and a device thereof are provided to efficiently release a used memory area by minimizing a waiting time for data processing when there is shared data access by memory accessors. CONSTITUTION: A memory allocator allocates copy sharing data for sharing data to an unused object when there is access to the sharing data by a second memory accessor in a state that a first memory accessor uses sharing data through a part of objects included in a first active block. An active block setting unit(120) generates/sets a second active block and sets a first active block as an inactive block when there is access to the sharing data by the second memory accessor in a state that all of the objects are used.

Abstract: PURPOSE: A VM(Virtual Machine) migration processing device and a method thereof are provided to minimize a data transmission delay and increase the use efficiency of network resources by performing the migration of a source VM to a physical device including a target having the highest coincidence with the source VM. CONSTITUTION: A migration target selecting unit(130) selects a source VM processed with migration among VMs implemented in nodes. A coincidence evaluating unit(140) extracts a target VM having the highest coincidence with the source VM by comparing the source VM with an image file of the VMs of the nodes. A migration processing unit(150) implements a migration VM of an image file format same as the source VM's on a target node in which the target VM is implemented.
