Abstract: For data intensive applications, a fine-Grained memory management scheme was proposed. The object-granularity data exchange between dynamic random access memory (DRAM) and swap device scheme was achieved. When DRAM is to be exhausted, the proposed scheme will swap data objects with low access frequency out to swap device, which reduces extra system I/O effectively. Compared to Linux-swap system, the proposed scheme improves system performance up to 37.5% in average.

Key words: computer system architecture, page swapping, data intensive application, virtual memory management, physical memory management
