| Abstract;On network distributed processing node architecture, MESCAR practicable on intranode communication with small software load using network wide sharing memory space, an intranode communication hardware (distributed memory coupler (DMC)) of its main construction element was experimentally produced, to carry out its feature evaluation by actually testing. DMC was a hardware automatically operable on data copying between distributed sharing memories (DSMs), and was instrumented at ATM network interface for a case of it. By some speed-up technologies such as introduction of pipe line in parallel operable on DSM access and ATM cell transfer, fixed arrangement of data in cell payloads, isolation of inner transmission and receiving buses, CRC of every cell units, parallel retreival of associated memories, effective access to control informations and buffers, and so on, 138 of throughput could be practiced between DMCs. And, latency between two mutually isolated nodes with messages including software processing, was 12. 3 micro second without dependent on message length. Simultaneously, it also had economical efficiency based on application of general purpose parts. MESCAR was suitable for communication rapidly and frequently transmitting and receiving relatively short messages, and could be expected for applications such as communication of intranode control informations in networks. |
