System and method for facilitating hybrid hardware-managed and software-managed cache coherency for distributed computing

A system comprising:

• a plurality of nodes in a cache-coherent interconnect network, wherein a respective node in a first subset of the nodes includes:
• a group of processors;
• a first plurality of memory groups with each memory group coupled to a processor;
• and
• a first plurality of node controllers with each node controller coupled to one or more processors;
• wherein a respective node in a second subset of the nodes includes:
• a second plurality of memory groups;
• and
• a second plurality of node controllers with each node controller coupled to a respective memory group in the second plurality of memory groups;
• and
• wherein each node controller of the first plurality of node controllers and the second plurality of node controllers comprises a cache coherence management logic, which includes:
• a first circuitry to maintain hardware-managed cache coherency in the cache-coherent interconnect network;
• and
• a second circuitry to facilitate software-managed cache coherency in the cache-coherent interconnect network;
• wherein the cache coherence management logic is further to:
• operate the first circuitry, in response to determining that a memory access request is destined to the first plurality of memory groups, wherein first plurality of memory groups corresponds to a hardware-managed cache-coherent space;
• and
• operate the second circuitry, in response to determining that a memory access request is destined to a third plurality of memory devices coupled to the node controller, wherein the node controller is coupled to the group of processors that are coupled to the first plurality of memory groups, and wherein the third plurality of memory devices corresponds to a software-managed cache-coherent space.
