Partial cache coherence

A method for partial cache coherence, the method performed by a memory coherency proxy in a node on a memory fabric, the method comprising:

• configuring a portion of a fabric memory on the memory fabric as a receive queue;
• exposing the receive queue to other nodes in the memory fabric as part of a fictitious local memory on the node;
• receiving, from a node on the memory fabric, a request to write a message into the receive queue;
• in response to receiving the request, updating cache lines corresponding to the request in a local processor cache on the node;
• and
• based on the received request, translating the received request into a command over the memory fabric to write the message into receive queue.

A node included in a memory fabric, comprising:

• a local cache connected to a local processor;
• and
• a memory coherency proxy to:
• configure a portion of remote fabric memory on the memory fabric as a proxy backing memory;
• expose the proxy backing memory to other nodes in the memory fabric as a fictitious local memory on the node having a memory address region different from a memory address region of a native local memory;
• assign a pointer to a sequence of bytes in the fictitious local memory;
• and
• share the pointer with the other nodes in the memory fabric.
