Characterizing memory performance in vector multiprocessors

Proceedings of the 6th international conference on Supercomputing - ICS '92, 1992
We propose a set of three memory performance measures directed at vector multiprocessors. One is the port reservation time which is closely related to the commonly-used memory bandwidth measure. The second is the vector fill time and is the latency through the memory system for an entire vector operation. The third is the slowest element time, which is

Vector Quantization I:Structure and Performance

1992
Vector quantization (VQ) is a generalization of scalar quantization to the quantization of a vector, an ordered set of real numbers. The jump from one dimension to multiple dimensions is a major step and allows a wealth of new ideas, concepts, techniques, and applications to arise that often have no counterpart in the simple case of scalar quantization.

Micro-architecture evaluation using performance vectors

ACM SIGMETRICS Performance Evaluation Review, 1996
Benchmarking is a widely used approach to measure computer performance. Current use of benchmarks only provides running times to describe the performance of a tested system. Glancing through these execution times provides little or no information about system strengths and weaknesses.

Improving DNA Vaccine Performance Through Vector Design

Current Gene Therapy, 2014
DNA vaccines are a rapidly deployed next generation vaccination platform for treatment of human and animal disease. DNA delivery devices, such as electroporation and needle free jet injectors, are used to increase gene transfer. This results in higher antigen expression which correlates with improved humoral and cellular immunity in humans and animals.

Performance Evaluation of Incremental Vector Clocks

2011 10th International Symposium on Parallel and Distributed Computing, 2011
The vector clock is an important mechanism to track logical time and causality in distributed systems. Vector clocks incur an overhead of n integers on each message, where n is the number of processes in the system. The incremental vector clock technique attaches only the changed components of the vector clock to a message. This technique to reduce the

Performance bounds for estimating vector systems

IEEE Transactions on Signal Processing, 2000
We propose a unified framework for the analysis of estimators of geometrical vector quantities and vector systems through a collection of performance measures. Unlike standard performance indicators, these measures have intuitive geometrical and physical interpretations, are independent of the coordinate reference frame, and are applicable to arbitrary

A high performance vector quantisation chip

Proceedings of IEEE Workshop on VLSI Signal Processing, 2002
A demonstrator chip is described for real time speech vector quantisation applications. The chip has been fabricated in a 1.2 micron CMOS technology and contains 38,000 transistors. It occupies a die area of only (4.8 /spl times/ 4.6) mm/sup 2 and can perform over 80 million multiply/accumulate operations per second.

Beamformer performance with acoustic vector sensors in air

The Journal of the Acoustical Society of America, 2006
For some time, compact acoustic vector sensors (AVSs) capable of sensing particle velocity in three orthogonal directions have been used in underwater acoustic sensing applications. Potential advantages of using AVSs in air include substantial noise reduction with a very small aperture and few channels.

Realizable Performance Vectors of a Finite-Source Queue

Operations Research, 1984
We study a scheduling problem on a finite-source queueing model which is identical to a two-stage closed Markovian cyclic queue consisting of a single-server (“processor”) and an infinite-server (“terminals”); each job has a distinct mean service time at the processor.
