A method for managing a shared memory, including: setting a master core, applying, by the master core, to a system for idle hugepage blocks, mapping the idle hugepage blocks to a virtual address space of the master core, and sorting the hugepage blocks in an ascending order of physical address size of the hugepage blocks; dividing, depending on whether the physical addresses are continuous, the hugepage blocks sorted into segments; in response to determining that there are segments satisfying the memory demand of the subsystem, sorting the segments satisfying the memory demand of the subsystem in a descending order of lengths thereof, and remapping the sorted segments to obtain segments having both continuous virtual addresses and continuous real addresses; and in response to determine that there is a segment satisfying the memory demand of the system, releasing hugepage blocks other than the segment satisfying the memory demand of the system.
