Abstract
A distributed computer system has a first subnet including a first group of endnodes and a second subnet including a second group of endnodes. Each endnode in the first and second groups of endnodes includes at least one process which produces and/or consumes message data, and queue pairs. Each queue pair includes a send work queue having work queue elements that describe message data for sending, and a receive work queue having work queue elements that describe where to place incoming message data. A communication fabric is physically coupled to the first group of endnodes and the second group of endnodes. A partitioning mechanism associates a first partition key representing endnodes in a first partition to a first group of queue pairs and a second partition key representing endnodes in a second partition to a second group of queue pairs for enabling communication between endnodes over the communication fabric.
