The Network Architecture of the Connection Machine CM-5

The Connection Machine Model CM-5 Supercomputer is a massively parallel computer system designed to offer performance in the range of 1 teraflops (1012floating-point operations per second). The CM-5 obtains its high performance while offering ease of programming, flexibility, and reliability. The machine contains three communication networks: a data network, a control network, and a diagnostic network. This paper describes the organization of these three networks and how they contribute to the design goals of the CM-5.

Functional VLSI design verification methodology for the CM-5 massively parallel supercomputer

The methodology and techniques developed from the functional verification of five of the VLSI chips used in the CM-5, a massively parallel supercomputer, are described. The verification methodology uses multiple layers of abstraction and concurrent development of design and test to reduce overall development time and increase the effectiveness and coverage of the functional tests. Some of the pragmatic techniques proved useful include continuous monitoring of all interfaces and finite-state machines (FSMs), and demons to exercise the chip in difficult-to-reach states.<<ETX>>
