Method of submitting work to fabric attached memory

A fabric attached memory (FAM) device of a distributed computing system, the FAM device comprising:

• a memory including a memory array of memory cells;
• a fabric interface to a fabric interconnect of the distributed computing system;
• at least one FAM computing resource located on a memory-side of the fabric interface;
• and
• a memory controller operatively coupled to the memory and the at least one FAM computing resource, wherein the memory controller includes a command manager (CM);
• and wherein the CM includes:
• a CM work queue local to the memory controller and configured to store work packets performable by the at least one FAM computing resource;
• a CM response queue configured to receive an indication of completion of the work packet from the FAM computing resource;
• and
• CM logic circuitry configured to:
• receive a work packet via the fabric interconnect from another CM of another FAM device, wherein the work packet includes a memory access to be performed by the at least one FAM computing resource;
• receive indication of completion of the work packet from the FAM computing resource in the CM response queue;
• and
• send a response packet to a CM response queue of the other CM in response to receiving receive indication of completion of the work packet.

A non-transitory computer readable storage medium including instructions that, when performed by processing circuitry of a memory controller of a fabric attached memory (FAM) device, cause the FAM device to perform acts comprising:

• receiving a work packet via a fabric interconnect at a first command manager (CM) of a memory controller of a first FAM device from a second CM of a second FAM device, wherein the work packet includes a memory access to be performed by a FAM computing resource local to the first FAM device;
• receiving, in a CM response queue of the first CM, indication of completion of the work packet from the FAM computing resource of the first FAM device;
• and
• sending, by the first CM, a response packet to a CM response queue of the second CM.
