A method, system, and storage medium for the InfiniBand.TM. Poll verb to support a multi-threaded environment without the use of kernel services to provide serialization for mainline Poll logic. Poll is the verb, which allows a consumer to determine which of its work requests have completed, and provides ending status. In addition to multiple concurrent threads using Poll against a single Completion Queue, Poll is serialized with Destroy Queue Pair and Destroy Completion Queue. Completion Queues are used to maintain completion status for work requests. Queue Pairs are used to submit work requests and are related to a Completion Queue at the time they are created.
