Design and Implementation of Task Scheduling Protocol in JAPS

计算机科学 , 2000,
Abstract: The automatic parallelizing is mainly to exploit the parallelism hidden in programs and run them in parallel without changing its origin semantic. The runtime task scheduling protocol is important to the parallel computing based on the distributed-memory systems. In this paper,we design and implement a task scheduling protocol for the Automatic Parallelizing System based on JAVA(JAPS). It can satisfy the dependence requirements while reducing the total communication load of the system.
PTSP:The Parallel Task Support Platform in JAPS

计算机科学 , 2000,
Abstract: In parallelizing compiling system,the functions and the efficiency of the runtime support pratform have a great impact on the result of the parallel execution. The thread and the RMI mechanisms in the Java language provide the distributed and parallel applications with efficient supports. In the automatic parallelizing compile system based on Java,we designed and implemented the parallel task support platform PTSP.

Abstract: 1引言 并行程序的设计、调试与维护相对于串行程序来说更为复杂和困难,于是人们开寻求用0O技术来开发并行系统。OO编程系统提供信息的封装性、继承性和多态性。封装性支高度的模块化,减
Application and Implementation of Multicast Technology in Real-time Video Ttansfer System

计算机科学 , 2000,
Abstract: In this paper we study the key issues of the real-time video transfer system when applying multicast technology.First we introduce an application-level high-performance multicast transport protocol RTMTP to offer guarantees of real-time and stable video transmission.Second,we improve the management of flow control by adding the component Video Repeater,avoiding the traditional way in which centralized and inflexible methods are applied.Third,packet forwarding is achieved through hierarchical service control of Repeaters.Finally,the implementation of a solution is issued and the performance of a sample system based on it is tested.
A New Broadcasting Model for CCC

计算机科学 , 2000,
Abstract: The topology of CCC has been widely adapted in the tightly-coupled systems for its particu-lar characteristics.In CCC.the performance of broadcasting is still an open issue.Usually,there are two modelsclassical and universal lists broadcasting models.But both of these models have some limitations in terms of complexity and performance.They either let each node store many transmission lists which use substantial unnecessary local memory.or use prescribed sequential selection which makes it lack adaptability and difficult to design. In this paper,the authors employ a new broadcasting model-ILBM—to design the broadcasting algorithm in CCC.This model proposes a selection algorithm that improves the adaptability and unifies the transmission lists,which ensure high performance broadcasting with small extra spatial cost,high adaptability,and convenience in implementation.
The Design and Implementation of a Parallel File System Based on The Heterogeneous Network of Workstation

计算机科学 , 2000,
Abstract: To improve the I/O performance of a parallel system, we designed and implemented a Parallcl File System Based On The Heterogeneous Network Of Wcrkstation(PFSHNOW). It is a cross-plat-form parallel file system,and has some characteristics such as parallelism, efficiency, cross-platform, convenience of management, and intelligence. This article described the model of the PFSHNOW and the advanced technique used in the file system. At the end, we also gave the result of evaluation.
软件学报 , 2005,
Abstract: 软件过程是以人为中心的系统,其特点是动态性和不断演化.既定过程模型在实际执行时往往有所偏差.基于e-cspe(extendedconstraintsonsucceedingandproceedingevents)约束实现过程验证和偏差测量.事件约束根据过程模型定义.过程实例执行被记录为事件序列.通过分析事件序列对事件约束的覆盖和违反结果,可以计算epd(eventconstraintbasedprocessdifferencemetric)和ead(eventconstraintbasedactivitydeviationmetric)指标.epd指标可以反映过程执行与过程模型的偏差,ead指标则为过程演化提供依据.
