What reading level is Parallel Queues And Pools An Evaluation book?
To quickly assess the difficulty of the text, read a short excerpt:
The ticket number is then used to order the tasks so that an insert follows a delete which follows an insert which follows a delete and so on. A single ticket is associated with each cell in the queue that indicates who's turn it is, either an insert or a delete.
10- Head and tail counters are maintained in the usual way. A circular array is used as storage to hold the user items. The algorithm requires two counters associated with the number of items on the queue. Filled and empty are the numb...er of cells in the queue that contain values and those that don't, respectively. They determine whether or not an insert or delete will initially fail. The number of items on the queue at any one time is just the value o{ filled.
This two counter scheme is necessary in order to avoid performing a tdr and tir on the same counter concurrently. This could (and did) lead to deadlock. If «+ 1 inserts begin and compete for n cells in the queue, as expected one insert will fail. Now if the failing insert is context switched out before it can increment the count then there will appear to be r?+ 1 items on the queue, allowing n+ 1 deletes to begin, one of which will endlessly wait for an item.
