Disaggregated memory pool assignment

At a compute node, a method, comprising:

• discovering one or more memory controllers attached to respective memory that forms a disaggregated memory pool, the disaggregated memory pool including a plurality of slices that are each dynamically assigned to a respective one of two or more compute nodes, the plurality of slices initially disabled;
• outputting to at least one of the one or more memory controllers a request for one or more of the plurality of slices;
• receiving an address range of the one or more slices assigned to the compute node;
• and
• executing memory transactions using the one or more slices.

At a compute node, a method, comprising:

• accessing a memory controller to discover a request regarding a slice of a disaggregated memory pool;
• where the request is to assign the slice to the compute node, add an address range of the slice to a memory map and execute memory transactions using the slice;
• and
• where the request is to free the slice from the compute node, query an operating system executed by the compute node to determine whether the slice can be freed.
