MULTITRANSPUTER SYSTEMS WITH DYNAMIC RECONFIGURATION CONTROL-BASED ONTHE SERIAL BUS

The paper presents new architectures of dynamically reconfigurable mul ti-transputer systems based on first generation transputers. Transpute r link connections in the proposed systems are organized in crossbar s witches on demand in the application program at run-time. Link connect ion reconfiguration control is based on transmission of control messag es through the serial bus compatible with the transputer link protocol . The bus is built using the TRANSBUS controller proposed and designed by IRESTE University of Nantes.(1) Two dynamically reconfigurable mul ti-transputer architectures are discussed. The first one, called GARTS , is based on nine-worker transputer clusters with unrestricted dynami c link connectivity. Inter-cluster connections are also dynamically or ganized. The second architecture, called HP-MODTRANS, is based on thre e-transputer fully connected clusters with dynamically organized inter -cluster link connections. The structures and functional properties of both architectures are discussed. Then, analytical model for reconfig uration control communication overheads and some performance figures o btained using these models are presented for the discussed architectur es.
