Abstract: A message passing interface processing system is described. In accordance with message passing logic, a node selects an affinity domain for communication of data associated with a message passing interface and selects a first rank of a first process of the message passing interface assigned to a first partition of the affinity domain as a first partition leader rank and an affinity domain leader rank. The node selects a second rank of a second process of the message passing interface assigned to a second partition of the affinity domain as second partition leader rank, receives the data at the first partition leader rank, and communicates the data from the first partition leader rank to the second partition leader rank.
