Abstract: A method and an apparatus for processing data and a computer system are provided. The method includes copying a shared virtual memory page to which a first process requests access into off-chip memory of a computing node, and using the shared virtual memory page copied into the off-chip memory as a working page of the first process; and before the first process performs a write operation on the working page, creating, in on-chip memory of the computing node, a backup page of the working page, so as to back up original data of the working page. Before a write operation is performed on a working page, page data is backed up in the on-chip memory, so as to ensure data consistency when multiple processes perform an operation on a shared virtual memory page while accessing off-chip memory as less as possible and improving a speed of a program.
