Abstract
A method and apparatus for the distributed processing of a file are disclosed. The apparatus includes a shared data block selection unit, a modified data block selection unit, a first file distributed-processing unit, and a second file distributed-processing unit. The shared data block selection unit selects at least one first data block to remain without change after distributed processing of a file. The modified data block selection unit selects at least one second data block to be modified after the distributed processing of a file. The first file distributed-processing unit allows an inode after the distributed processing of a file to point to the first data blocks so that the first data block is shared before and after the distributed processing of a file. The second file distributed-processing unit allows the inode after the distributed processing of a file to point to at least one third data block.
