Abstract
A system comprises a plurality of nodes coupled together via a switching device. Each node comprises a processor coupled to a memory. Migration logic in the switching device is configured to migrate segments of each memory to the switching device.
Claims18
A system, comprising:
- a plurality of nodes, each node comprising a processor coupled to a memory;
- and
- a switching device coupled to the plurality of nodes and containing migration logic that is configured to identify segments of memory that are each accessed above a threshold, said threshold defining both a number of times a segment is accessed and a time period for the number of times, and that is configured to migrate segments of each memory so identified to a memory of the switching device so that each migrated segment is accessible to each of the processors.
A switch, comprising:
- a means for coupling to a plurality of nodes;
- a means for determining whether a set of data has been accessed more than a threshold number of times in a given time period to identify frequently accessed sets of data stored in the plurality of nodes;
- and
- a means for copying the identified sets of data from the plurality of nodes to a memory in the switch.
1 more element
A method, comprising:
- identifying memory segments that are accessed over a threshold, said threshold specifying both a number of times and an associated time period;
- and
- copying the identified segments to a memory of a switching device that couples together a plurality of processing nodes.
