    The Cydra 5 is a heterogeneous multiprocessor system that targets small work groups or departments of scientists and engineers. The two types of processors are functionally specialized for the different components of the work load found in a departmental setting. The Cydra 5 numeric processor, based on a directed-data-flow architecture, provides consistently high performance on a broader class of ... View full abstract»

    The Convex C220 and C240 supercomputers are a family of 64-bit multiprocessors, tightly coupled through a shared main memory. Each processor contains an integrated vector processor. All processor features, including the vector processor, are controlled by a microcoded instruction set. The system is implemented in 100 K emitter-coupled logic, with a cycle time of 40 ns. The author shows some of the... View full abstract»

    The authors' experience in designing and manufacturing the Cray X-MP supercomputer is described. The X-MP is a multiprocessor design built on the basic architecture of the Cray-1 and incorporates the 16-gate emitter-coupled logic gate arrays used in the Cray-2 project. The goal was a two-processor machine compatible with the Cray-1 but with performance 1.5 to 2 times better. The authors examine th... View full abstract»

    The authors describe some of the design decisions that determined the architecture and implementation of the Advanced Scientific Computer (ASC). They explain why certain design decisions were made, with a retrospective evaluation. They discuss the architecture, central processor, peripheral processor, circuits and packaging, and cooling. Looking back over this twenty-year project, the authors eval... View full abstract»

    The authors examine the performance, cost, and schedule tradeoffs made for the NS 32532, a 32-bit general-purpose microprocessor. Among its features are a 30-MHz clock frequency, three on-chip caches, a four-stage pipeline, and dedicated mechanisms for multiprocessing support. The authors describe the design constraints set by the VLSI processing and packaging technologies. They address the issue ... View full abstract»
