Abstract
A host channel adapter is configured for servicing a work notification, supplied by a host process to an assigned destination address accessable by the host channel adapter, based on matching the assigned destination address with a stored notification address from one of a plurality of queue pair context entries stored within the host channel adapter. The host channel adapter receives a queue pair context entry including a notification address, based on creation of a corresponding queue pair for a host process. The queue pair enables the host process to post a work descriptor and output a work notification to the host channel adapter by writing the work notification to an assigned destination address. The host channel adapter matches the assigned destination address with a stored notification address, and services the work descriptor based on the corresponding queue pair attributes specified in the identified queue pair context entry.
