Dynamic load based memory tag management

A system for managing a memory comprising:

• a memory control unit configured to:
• receive a command, wherein the command comprises a command type that either requires or does not require buffering resources;
• determine a number of available memory tags from a first set of memory tags that are associated with the buffering resources;
• determine a number of available memory tags from a second set of memory tags that are not associated with the buffering resources;
• dynamically adjust an assignment of memory tags for use in the second set of memory tags based on the command type, the number of available memory tags from the first set of memory tags, and the number of available memory tags from the second set of memory tags, wherein the memory control unit is configured to dynamically adjust the assignment of the memory tags for use in the second set of memory tags by:
• determining, via the memory control unit, whether the number of the second set of memory tags exceeds a first threshold indicative of a number of memory tags in use;
• and
• determining, via the memory control unit, whether the number of the first set of memory tags exceeds a second threshold indicative of a number of memory tags in use;
• and
• prevent any further allocation of a subset of the second set of memory tags when the first set of memory tags have exceeded the second threshold indicative of a number of memory tags in use.

A computer program product for managing a memory control unit comprising, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a memory control unit to cause the memory control unit to perform a method comprising:

• receiving a command at the memory control unit, wherein the command comprises a command type that either requires or does not require buffering resources;
• determining, via the memory control unit, a number of available memory tags from a first set of memory tags that are associated with the buffering resources;
• determining, via the memory control unit, a number of available memory tags from a second set of memory tags that are not associated with the buffering resources;
• dynamically adjusting, via the memory control unit, an assignment of memory tags for use in the second set of memory tags based on the command type, the number of available memory tags from the first set of memory tags, and the number of available memory tags from the second set of memory tags, wherein dynamically adjusting the assignment of the memory tags for use in the second set of memory tags comprises:
• determining, via the memory control unit, whether the number of the second set of memory tags exceeds a first threshold indicative of a number of memory tags in use;
• and
• determining, via the memory control unit, whether the number of the first set of memory tags exceeds a second threshold indicative of a number of memory tags in use;
• and
• preventing any further allocation of a subset of the second set of memory tags when the first set of memory tags have exceeded the second threshold indicative of a number of memory tags in use.
