This paper discusses a new principle of interconnection network for massively parallel architectures in the field of numerical computation. The principle is motivated by an analysis of the application features and the need to design new kind of communication networks combining very high bandwidth, very low latency, performance independence to communication pattern or network load and a performance improvement proportional to the hardware performance improvement. Our approach is to associate compiled communications and a circuit switched interconnection network. This paper presents the motivations for this principle, the hardware and software issues and the design of a first prototype. The expected performance are a sustained aggregate bandwidth of more than 500 GBytes/s and an overall latency less than 270 ns, for a large implementation (4K inputs) with the current available technology.
