Study on large-scale scalable P2P grid infrastructure for large-capacity distributed computing

P2P网格的概念是利用办公室和实验室中的pc作为网格计算的计算资源，利用P2P技术，而网格计算主要是为了在各个研究机构中共享计算资源。我们的目标是研究和建立大容量计算的P2P网格技术和基础设施，并在几个应用中证明其有效性。为了利用潜在的计算资源，如办公室中的pc作为网格计算的计算源，我们开发了一个称为BEE的系统，它使Linux二进制文件能够在Windows中运行网格工作程序，并开发了一个网络层，它允许通过udp穿孔来穿越防火墙进行通信。在此基础上，提出了一种支持匿名和恶意用户识别的P2P环境下的AUBReX（基于Cross证书代表的Buddy-buddy关系的认证方法）认证方法，并提出了一种基于远程过程调用的并行编程模型框架，该模型可以跨越多个网格作业调度系统管理的大规模计算资源池。我们提出了一个模型，将数据管理层的数据传输与RPC编程分离开来。我们设计并实现了一个原型数据传输层omnstorage，它可以实现大量数据的高效数据传输。提出了支持全局分布式文件系统大容量计算的框架和编程模型。我们提出了一种基于可扩展散列的DHT存储和检索XML数据的方案。针对一类广义特征值问题的若干特征值和特征向量，提出了一种适用于P2P网格中主工规划模型的主工型并行求解方法。我们还开发了适用于异构多核系统的数值算法，如Cell处理器，可以被认为是P2P网格中强大的计算资源。少

The concept of P2P grid is to make use of PCs in office and laboratory as a computing resource of Grid computing using P2P technology, while the Grid computing is mainly for sharing computing resource in each research organization. Our objective is to investigate and establish the technology and infrastructure of P2P grid for large-capacity computing and demonstrate its effectiveness in several applications.1. To make use of potential computing resources such as PCs in office as a computing source of grid computing, we have developed a system, called BEE, which enables the Linux binary to run a Grid worker in Windows, and a network-layer which allows the communication traversing the firewall by using UDP-hole punching. And, we also proposed an authentication method called AUBReX (Authentication method Using Buddy-buddy relationship Represented by Cross certificate), which supports both anonymity and malicious user identification, for P2P environment, and a framework for a parallel prog … More ramming model by remote procedure calls, which bridge large-scale computing resource pools managed by multiple Grid-enabled job scheduling systems.2. We proposed a model to separate the data transfer by a data management layer from the RPC programming. We have designed and implemented a prototype data transfer layer, OmniStorage, which allows efficient data transmission of a large amount of data. And we proposed a framework and programming model to support large capacity computing on global distributed file system. We have proposed a scheme for storage and retrieval of XML data using DHT with storage-load balancing method based on extendible hashing.3. We have developed a master-worker type parallel method for finding several eigenvalues and eigenvectors of a generalized eigenvalue problem, which suitable for master-worker programming models in P2P grid. We have also developed numerical algorithms suited to the heterogeneous multi-core systems such as Cell processor which can be recognized as a powerful computing resource in P2P grid. Less
