A queuing system wherein at least one input/output (I/O) interface having
an outbound queue. A plurality of processing units is coupled to the at
least one I/O interface. Each one of the processing units is coupled to a
corresponding processing unit memory. Each one of the processing unit
memories has an inbound queue for such coupled processing unit. The at
least one I/O interface outbound queue stores outbound information being
returned to the I/O interface after being processed by one of the
processing units. The I/O interface creates queue indices for storage in
the inbound queues of the processor unit memories. The I/O interface
includes a translation table, such table storing at a location a producer
index for the plurality of processing units and a consumer index for such
plurality of processing units.
