Abstract:
Most parallel operating systems and most message passing system implementations use the same three way connectionless communication protocol. Unfortunately, this protocol is not very well suited for the needs of most parallel applications, resulting in high latency and poor throughput. This paper analyzes the widely used connectionless protocols and compares them with connection oriented protocols. For this comparison, all these protocols have been implemented in the operating system COSY and in an event driven simulator. The measurements and simulations clearly show the superiority of the connection-oriented protocols, which deliver a throughput up to eight times higher as the three-way-protocol.
