%X Recent developments in the area of high performance
   computing are pointing the way to a standard architecture
   for parallel computers. This architecture contains a number
   of medium\-cost processing elements which communicate with
   each other through a high\-bandwidth, low\-latency
   interconnect. The design of the interconnect eliminates the
   concerns of "locality" which are current in the
   programming of present\-day machines. This "flat"
   topology and common architectural model lead to increased
   opportunities for establishing portable software for high
   performance computing. The Esprit GP\-MIMD project has
   exploited these opportunities by developing the
   architectural model and denning a programming interface for
   software which runs efficiently on machines with a range of
   processing power.
