Abstract
Point-to-point intra-nodelet messaging support for nodelets on a single chip that obey MPI semantics may be provided. In one aspect, a local buffering mechanism is employed that obeys standard communication protocols for the network communications between the nodelets integrated in a single chip. Sending messages from one nodelet to another nodelet on the same chip may be performed not via the network, but by exchanging messages in the point-to-point messaging buckets between the nodelets. The messaging buckets need not be part of the memory system of the nodelets. Specialized hardware controllers may be used for moving data between the nodelets and each messaging bucket, and ensuring correct operation of the network protocol.
