An Adaptive Method for Maintaining I/O Data Coherence of Multi-Core Systems

I/O data consistency problem is an important factor which multiple processors systems can not ignore.Multiple cores make the I/O consistency of processors become more and more severe.On the other hand,diversity of I/O pattern makes it's difficult to find a method which can satisfy different applications.Based on analysis of I/O pattern,we put forward seven characteristics of I/O workloads;Then presented a novel adaptive method for maintaining I/O data coherence in multi-core systems;Finally,the test results of our method would be shown,and we can find the method can satisfy different I/O workloads.
