LOCK-FREE SERIALISING ACCESS TO SHARED RESOURCES |
摘要 |
<p>A method for serializing process access to shared resources utilizing low-level atomic functions to maintain control structures in which noncontiguous words must be modified at two different times. The atomic functions require an initiation operation partitionable from a completion operation. Each process requesting access to the shared resource performs the initiation operation, which begins modification of a control structure. The completion operation may be performed by the original process if there is no resource conflict. If, however, another process is currently modifying the control structure, then the task of performing the completion operation is passed to one of the concurrently-accessing processes.</p> |
