    摘要: According to an embodiment, a computer system for cache management includes a processor and a cache, the computer system configured to perform a method including receiving a first store request for a first address in the cache and receiving a first fetch request for the first address in the cache. The method also includes executing the first store request and the first fetch request, latching the first store request in a store write-back pipeline in the cache, detecting, in the processor, a conflict following execution of the first store request and the first fetch request and receiving the first store request from a recycle path including the store write-back pipeline and executing the first store request a second time.

    摘要: A system, method and computer program product for sampling computer system performance data are provided. The system includes a sample buffer to store instrumentation data while capturing trace data in a trace array, where the instrumentation data enables measurement of computer system performance. The system further includes a sample interrupt generator to assert a sample interrupt indicating that the instrumentation data is available to read. The sample interrupt is asserted in response to storing the instrumentation data in the sample buffer.
