Method using stream prefetching history to improve data prefetching performance. |
摘要 |
Computer implemented method, system and computer program product for prefetching data in a data processing system. A computer implemented method for prefetching data in a data processing system includes generating attribute information of prior data streams by associating attributes of each prior data stream with a storage access instruction which caused allocation of the data stream, and then recording the generated attribute information. The recorded attribute information is accessed, and a behavior of a new data stream is modified using the accessed recorded attribute information.
