一个基于消息传递接口和面向对象的图像信号处理并行向量库

传统并行软件系统的设计和实现存在着开发效率低、质量难以保证和可移植性差等问题。针对这些问题,采用开发标准并行库的方法加以解决。借鉴高性能嵌入式计算软件计划(high performance embedded computing software initiative,HPEC_SI)的解决方法,基于消息传递接口(message passing interface,MPI)的消息传递机制,对图像/信号处理中的一些典型并行算法以类组件的方式进行封装,设计和实现了具有面向对象特征的、用于图像/信号处理的并行向量库,提供给应用软件开发人员一个良好的开发环境。通过测试和实验证明,该库可以高效地实现相应的向量矩阵并行算法,并具有简单易用、可复用性和可移植性强、效率高的特点。

Design and implementation of image/signal processing parallellibrary based on MPI and object-orientation

There are many problems in the design and realization of traditional parallel software systems, such as the low development efficiency, the difficulty to ensure the quality and the poor portability. This paper developed the standard parallel library to resolve these problems. This paper used the idea of HPEC_SIhigh performance embedded computing software initiative for reference, based on the message passing mechanism of MPImessage passing interface, enveloped some typical parallel algorithms in image/signal processing domain as classes, designed and finished an object-oriented, image/signal processing standard parallel library to provide application software programmers an excellent development environment. It proves that the matrix-vector parallel algorithms can be implemented effectively by the library through experiments, and it's easy to use, portable and reusable greatly and effective.
