Software support for multiprocessor latency measurement andevaluation

Parallel computing scalability evaluates the extent to which parallel programs and architectures can effectively utilize increasing numbers of processors. In this paper, we compare a group of existing scalability metrics and evaluation models with an experimental metric which uses network latency to measure and evaluate the scalability of parallel programs and architectures. To provide insight into dynamic system performance, we have developed an integrated software environment prototype for measuring and evaluating multiprocessor scalability performance, called Scale-Graph. Scale-Graph uses a graphical instrumentation monitor to collect, measure and analyze latency-related data, and to display scalability performance based on various program execution patterns. The graphical software tool is X-Windows based and is currently implemented on standard workstations to analyze performance data of the KSR-1, a hierarchical ring-based shared-memory architecture     

Combinations of weak classifiers

To obtain classification systems with both good generalization performance and efficiency in space and time, we propose a learning method based on combinations of weak classifiers, where weak classifiers are linear classifiers (perceptrons) which can do a little better than making random guesses. A randomized algorithm is proposed to find the weak classifiers. They are then combined through a majority vote. As demonstrated through systematic experiments, the method developed is able to obtain combinations of weak classifiers with good generalization performance and a fast training time on a variety of test problems and real applications. Theoretical analysis on one of the test problems investigated in our experiments provides insights on when and why the proposed method works. In particular, when the strength of weak classifiers is properly chosen, combinations of weak classifiers can achieve a good generalization performance with polynomial space- and time-complexity.

三节点环网中输电线路的故障测距

在环网中，由于网孔中有环网电流，故障线路障碍点两则的电流不再服从简单的并联支路电流分配的规律。因此，文献中大量引用的“双侧电源单一线路”的测距计算公式，不适用不环网，本文推导出三节点环网中输电线路故障测距的计算公式，模拟计算结果表明：所推导了计算公式是正确的，可用于具有相同拓扑结构的环网。
