Systems and methods for efficient compressed cache line storage and handling

A data management method comprising:

• storing data units in private caches in a plurality of nodes of a multiprocessor system, wherein each node includes at least one processor, at least one cache private to the node and at least one cache location buffer (CLB) private to the node;
• and
• for at least one node from among the nodes of the multiprocessor system,
• storing, in the at least one CLB included in the at least one node, a plurality of location information values, each location information value indicating a location associated with a respective data unit, wherein each location information value stored in the at least one CLB indicates the location associated with the respective data unit to be,
• a location within the at least one private cache included in the at least one node,
• a location in one of the plurality of nodes other than the at least one node, or
• a location in a main memory, and
• encoding at least one location information value from among the plurality of location information values with a symbol which indicates that a data unit stores a first value.

A non-transitory, computer-readable storage medium comprising computer-executable instructions that, when executed by a computer, cause the computer to perform operations including:

• storing data units in private caches included in a plurality of nodes of a multiprocessor system, in global caches and a memory, wherein each node includes at least one processor and at least one cache private to the node,
• the plurality of nodes being connected via a network;
• and
• for at least one node from among the plurality of nodes,
• storing a plurality of location information values in a cache location buffer private to the at least one node;
• and
• encoding at least one location information value from among the plurality of location information values with a symbol which indicates a data unit stores a first value.
