Abstract

Described are techniques for communicating between one or more producers and one or more consumers. A first consumer of an event queue registers for notification regarding occurrences of one or more events. A producer of the event queue posts one or more notifications to one or more consumers of the event queue regarding one or more occurrences of one or more events. Each of the consumers receive notification regarding occurrences of events for which the consumer is registered. The first consumer retrieves posted event notifications regarding events for which the first consumer is registered. If the first consumer is executing in user space and an event notification list to which the event notifications for the first consumer are posted is located in shared memory, the first consumer retrieves the posted event notifications without proxying into kernel space.
