The Myrinet local area network employs the same technology used for packet communication and switching within massively parallel processors. In realizing this distributed MPP network, we developed specialized communication channels, cut-through switches, host interfaces, and software. To our knowledge, Myrinet demonstrates the highest performance per unit cost of any current LAN. >

Myrinet: a gigabit-per-second local area network

This paper presents a new reflectance model for rendering computer synthesized images. The model accounts for the relative brightness of different materials and light sources in the same scene. It describes the directional distribution of the reflected light and a color shift that occurs as the reflectance changes with incidence angle. The paper presents a method for obtaining the spectral energy distribution of the light reflected from an object made of a specific real material and discusses a procedure for accurately reproducing the color associated with the spectral energy distribution. The model is applied to the simulation of a metal and a plastic.

Distributed average consensus with least-mean-square deviation

Gossip algorithms are attractive for in-network processing in sensor networks because they do not require any specialized routing, there is no bottleneck or single point of failure, and they are robust to unreliable wireless network conditions. Recently, there has been a surge of activity in the computer science, control, signal processing, and information theory communities, developing faster and more robust gossip algorithms and deriving theoretical performance guarantees. This paper presents an overview of recent work in the area. We describe convergence rate results, which are related to the number of transmitted messages and thus the amount of energy consumed in the network for gossiping. We discuss issues related to gossiping over wireless links, including the effects of quantization and noise, and we illustrate the use of gossip algorithms for canonical signal processing tasks including distributed estimation, source localization, and compression.

Diffusion is a well-known algorithm for load-balancing in which tasks move from heavily-loaded processors to lightly-loaded neighbors This paper presents a rigorous analysis of the performance of the diffusion algorithm on arbitrary networks It is shown that the running time of the diffusion algorithm is bounded by: Ω(log σ/Γ) ≤ Time ≤ O(Nσ/Γ) and Ω(log σ/decimal: Γ) ≤ Time ≤ O(σ/decimal: Γ2), where N is the number of nodes in the network, σ is the standard deviation of the initial load distribution (which represents how imbalanced the load is initially), and Γ and decimal: Γ are the network's electrical and fluid conductances respectively (which are measures of the network's bandwidth) For the case of the generalized mesh with wrap-around (which includes common networks like the ring, 2D-torus, 3D-torus and hypercube), we derive tighter bounds and conclude that the diffusion algorithm is inefficient for lower dimensional meshes

An analysis of diffusive load-balancing

The gradual refinement of a general approach to two-dimensional sorting, the shear-sort algorithm, to more sophisticated and specialized sorting algorithms on mesh-connected computers is described. The analysis of the shear-sort algorithm gives rise to a novel perspective of two-dimensional sorting, which seems to be a very powerful tool for developing efficient algorithms. The same methods can be extended for sorting in higher dimensions, for example, in the three-dimensional mesh. The concept of clean and dirty rows can be modified to clean and dirty planes (or hyperplanes for dimensions greater than three). Although only two schemes (purely recursive and iterative) are explicitly described, the reader may construct his own algorithm using similar technique and slight modifications. Designing an O(n) algorithm for sorting on a mesh becomes much simpler using the techniques developed. >

Parallel sorting in two-dimensional VLSI models of computation

Given a sequence of numbers which can be mapped into an m x n array, the sorting of rows and columns is shown to yield an overall sorted sequence. This unusually simple procedure is proven to require O(log2m) iterations by analyzing the data movement in the array under successive row and column sorts. An efficient bubble sort network suitable for VLSI implementation with near-optimal area-time-squared performance is a direct application of the row-column sorting technique.

Interconnection Networks for High-Performance Parallel Computers

A simple but powerful architecture based on the classical associative processor model is proposed. By distributing logic among slices of storage cells such that a number of bit-planes share a simple logic unit, bit-parallel arithmetic for massively parallel processing becomes feasible. For m-bit operands, this architecture enables complex operations such as multiplication and division to execute in O(m) cycles as opposed to O(m/sup 2/) for bit-serial machines. Algorithms which utilize this bit-parallel property to efficiently perform operations on floating point data have been developed. The simplicity of the architecture enables its implementation using VLSI technology, and hence allows the construction of a word-parallel, bit-parallel, massively parallel (P/sup 3/) computing system. Implementations of the fast Fourier transform and matrix multiplication are presented to illustrate the operation of this system. >
