Early prediction of the write-back cache blocks that shared memory in a computer system, owned

摘要

Method of predicting early write-back cache blocks that are owned by the shared memory computer system. The CPU that enables the system to predict that may be required by the CPU of the other blocks written is high, owns the invention, as soon as a memory after updating the data in the block I will write back a block of them. If another processor is requesting the data, it is possible to reduce the waiting time for obtaining the data, it is possible to reduce the overhead of synchronization, which can increase the throughput of a parallel program.
