Abstract:

An address map has mapping data specifying a mapping between virtual addresses and physical addresses in persistent memory, consistent with both a memory mapped mode of access to data in a first data group and a block mode of access to the same data in the first data group. When using the block mode of access, a memory request by the user application is translated, in accordance with the address map, into a block mode persistent memory access command, for example using a file system and a block driver. When using the memory mapped mode of access, a memory request by the user application is translated, in accordance with the address map, into a direct persistent memory access command, bypassing the file system and block driver.
