Data placement with packet metadata

A method comprising:

• maintaining, in a memory, a programmable list of events comprising a plurality of entries, where each of the entries is configured to store:
• an identification of criteria that indicate an occurrence of an event;
• and
• a priority;
• monitoring, by a traffic analyzer, a stream of packets traversing a link, each of the packets comprising a memory access request;
• and
• responsive to the stream of packets meeting criteria associated with an event identified by an entry of the plurality of entries, programming a direct memory access (DMA) device to cause data corresponding to a data region targeted by a memory request of the stream of packets to be moved from a first memory device to a second memory device different from the first memory device.

A system comprising:

• a first processor coupled a first memory device;
• a second processor coupled to a second memory device;
• a link connecting the first processor and the second processor;
• and
• a traffic analyzer comprising circuitry configured to:
• maintain, in a memory, a programmable list of events comprising a plurality of entries, where each of the entries is configured to store:
• an identification of criteria that indicate an occurrence of an event;
• and
• a priority;
• monitor a stream of packets generated by circuitry of the first processor traversing the link, wherein the stream of packets comprise memory access requests that target the second memory device;
• and
• responsive to the stream of packets meeting criteria associated with an event identified by an entry of the plurality of entries, program a direct memory access (DMA) device to cause data corresponding to a data region stored in the second memory device to be moved to the first memory device.
