    Abstract: Systems, methods, and apparatuses relating to circuitry to precisely monitor memory store accesses are described. In one embodiment, a system includes a memory, a hardware processor core comprising a decoder to decode an instruction into a decoded instruction, an execution circuit to execute the decoded instruction to produce a resultant, a store buffer, and a retirement circuit to retire the instruction when a store request for the resultant from the execution circuit is queued into the store buffer for storage into the memory, and a performance monitoring circuit to mark the retired instruction for monitoring of post-retirement performance information between being queued in the store buffer and being stored in the memory, enable a store fence after the retired instruction to be inserted that causes previous store requests to complete within the memory, and on detection of completion of the store request for the instruction in the memory, store the post-retirement performance information in storage of the performance monitoring circuit.

    Abstract: An apparatus and method are described for prefetching data with hints. For example, one embodiment of a processor comprises: a plurality of cores to process instructions; a first core of the plurality of cores comprising: decoder circuitry to decode instructions indicating memory operations including load operations of a first type with shared data hints and load operations of a second type without shared data hints; execution circuitry to execute the instructions to perform the memory operations; data prefetch circuitry to store tracking data in a tracking data structure responsive to the memory operations, a portion of the tracking data associated with the first type of load operations; and the data prefetch circuitry to detect memory access patterns using the tracking data, the data prefetch circuitry to responsively issue one or more prefetch operations using shared data hints based, at least in part, on the portion of the tracking data associated with the first type of load operations.
