Performing memory RAS operations over a point-to-point interconnect

A distributed memory system comprising:

• an unordered point-to-point interconnect;
• and
• at least two components coupled to the interconnect, at least two of the at least two components including:
• a memory engine to identify address conflicts of memory transactions in the distributed memory system, and to serialize the conflicts to maintain coherence due to an unordered interconnect;
• a memory write queue to store at least one memory transaction received by the memory engine;
• a pending memory write queue to store at least one memory transaction if an address conflict is identified by the memory engine;
• and
• a memory interface to couple the memory engine to a memory.

A method comprising:

• receiving a memory transaction that was sent over an unordered point-to-point interconnect in a distributed memory system;
• determining whether an address conflict exists between the memory transaction and another memory transaction;
• and
• if the address conflict exists waiting until the conflict is resolved before forwarding the memory transaction.

An article comprising a computer readable medium having instructions thereon which when executed cause a computer to:

• receive a memory transaction that was sent over an unordered point-to-point interconnect in a distributed memory system;
• determine whether an address conflict exists between the memory transaction and another memory transaction;
• and
• if the address conflict exists wait until the conflict is resolved before forwarding the memory transaction.
