....destination node, the router places the message in the appropriate network input queue for its priority. The head of each message queue is mapped into the register file of a dedicated thread slot, which allows the message handler thread to respond very quickly to incoming messages. As discussed in [21], this network interface allows lower latency messaging than architectures which map network control registers into their memory address space or which require explicit copying of messages into message buffers. It would have been possible to reduce message latency by using a streaming message ....
....contributors to the access time, they are not good candidates for additional hardware support due to the costs involved in providing such support. Considerable effort has been devoted to reducing the latency of the M Machine s event system, leaving little room for improvement. As is discussed in [21], the latency of the MAP chip s message system could be improved slightly through the use of a streaming network input system instead of requiring that threads compose messages in their register files before sending them, but this would make it much harder for the MAP to guarantee each thread fair ....
