Abstract
A queue is disclosed (i) that provides for single-channel and multi-channel operation and that can change between single-channel and multi-channel operation during operation hitlessly, (ii) in which the number of channels and each channel's size can be changed during operation hitlessly, and (iii) is compact. To accomplish this, the illustrative embodiment comprises a group of doubly-linked lists, one for each channel's storage. One set of links indicates the node where the next datum is to be written and the other set of links indicates the node where the next datum is to be read. By bifurcating each channel's queue into a set of write links and read links, the illustrative embodiment can resize a channel during operation hitlessly.
