    Abstract: A processor includes a memory subunit that includes a status register and an execution engine unit to: randomly select a load operation to monitor; determine a re-order buffer identifier of the load operation; and transmit the re-order buffer identifier to the memory subsystem. Responsive to receipt of the re-order buffer identifier, the first memory subunit is to store a piece of information, related to a status of the load operation, in the status register. The processor also includes logic to, responsive to detection of retirement of the load operation, store memory information in memory-related fields of a record of a memory buffer. The memory information includes auxiliary information (AUX) and access latency information, wherein one of the auxiliary information or the access latency information includes the piece of information, from the status register, stored in a particular field of the memory-related fields.

    Abstract: A processor includes a memory subsystem having a first memory subunit that includes a status register and an execution engine unit coupled to the memory subsystem. The execution engine unit is to: randomly select a load operation to monitor; determine a re-order buffer identifier of the load operation; and transmit the re-order buffer identifier to the memory subsystem. Responsive to receipt of the re-order buffer identifier, the first memory subunit stores a piece of information, related to a status of the load operation, in the status register. Responsive to detection of retirement of the load operation, the first memory subunit is to store the piece of information from the status register into a particular field of a record of a memory buffer, wherein the particular field is associated with the first memory subunit.
