Abstract(in English)	In order to use a PCIe-connected flash storage as extended memory beyond DRAM main memory, the newly proposed Linux swap system designed for a flash storage was evaluated. Results showed that using malloc (3) under the new swap system, where the flash storage was used as a swap device, brought us limited advantage, compared with using file mmap (2), where the flash storage was used as a ordinary file system. By these observations, we proposed a user-friendly framework to utilize a flash-based extended memory for existing application programs and users.
