Slidable dynamic share memory buffer pool

In order to make full use of share memory to improve the data communication efficiency between threads, the use of a slidable dynamic share memory buffer pool is proposed to realize the large volume of data communication between threads, this means, a whole piece of space is applied as the memory buffer pool for all threads, a certain number of unidirectional index queues are constructed, and each index queue represents a data buffet zone. The number of nodes in each index queue can be increased or decreased as requirement for memory management so that the memory occupied by each data buffet zone can be slid appropriately. Theoretical analysis and test results show that the use of slidable dynamic share memory buffer pool improves the utilization of the whole memory buffet zone and the data communication efficiency.
