Method, system, and computer program products for data movement within processor storage

A computing system for performing data page operations, said computing system comprising:

• a physical memory in which data referenced by memory addresses is stored;
• a processing device for generating one or more real addresses associated with memory locations of the physical memory for reading and writing data;
• a translation mechanism for mapping respective pages of contiguous memory addresses to corresponding locations in said physical memory in accordance with a specified mapping, whereby a first page of memory addresses is mapped to a first location in said physical memory and a second page of memory addresses is mapped to a second location in said physical memory;
• the translation mechanism changing said specified mapping to a new mapping in which said second page of memory addresses is mapped to said first location in said physical memory, thereby effectively moving said data stored at said first location from said first page of memory addresses to said second page of memory addresses without moving said data between locations in said physical memory.

A computer program product for moving data between memory addresses in a computer system in which data referenced by the memory addresses is stored in a physical memory, the computer program product comprising:

• a storage medium;
• and
• program instructions stored on the storage medium for implementing:
• providing a translation mechanism for mapping respective pages of contiguous memory addresses to corresponding locations in said physical memory in accordance with a specified mapping, whereby a first page of memory addresses is mapped to a first location in said physical memory and a second page of memory addresses is mapped to a second location in said physical memory;
• and
• changing said specified mapping of said translation mechanism to a new mapping in which said second page of memory addresses is mapped to said first location in said physical memory, thereby effectively moving said data stored at said first location from said first page of memory addresses to said second page of memory addresses without moving said data between locations in said physical memory.
