摘要

桌面网格是分布式计算的一种形式，它收集空闲桌面计算机的计算能力，无论这些计算机是志愿者还是部署在机构中。本文提出设计并实现一个基于云存储的桌面网格客户端框架，该框架还可以按需向志愿机器交付遗留应用程序。从技术角度来看，将实现基于用户级虚拟化的隔离执行环境:一方面，截取应用程序的一些资源访问api并将其重定向到实际存储位置(在云上);因此，遗留应用程序无需安装即可运行，以简化维护。另一方面，该机制还可以构造沙盒来限制应用程序的访问范围，以保证安全性。该方案采用了有前途的云相关技术来满足志愿计算的需求，测试表明它只造成有限的性能损失。

Using User-Level Virtualization in Desktop Grid Clients for Application Delivery and Sandboxing

Desktop grid is a form of distributed computing that harvests the computing power of idle desktop computers whether these are volunteers or deployed at an institution. This paper proposes to design and implement a client-end framework of desktop grid, based on cloud storage, which can also deliver legacy applications on-demand to volunteer machines. From technical viewpoint, an isolated execution environment based on user-level virtualization will be achieved: on one side, some resource-accessing APIs for applications are intercepted and redirected to real storage positions (on the cloud); therefore legacy applications can run without installation to simplify maintenance. On the other side, this mechanism can also construct a sandbox to restrict the access range of applications for security. This proposal adopts promising cloud-related technologies for requirements of volunteer computing, tests show that it only causes limited performance loss.
