This ITR proposal is a request for funding to address the two critical scaling problems for large scale grid computing. Experience with the current generation of deployed grid systems makes it clear that, while these systems are practical for tens of sites, with tens of full-time managers, they do not scale to the hundreds or thousands of sites required by large scientific collaborations or to larger global scales. The two essential non-scaling effects are: (a) Software Environment Computing (SEC): a lack of well-defined mechanisms for constructing and manipulating software environments on remote sites reliably, safely and without human intervention is a major source of non-scaling behavior. The solution proposed is to define and implement an infrastructure where software environment creation and manipulation are basic elements of grid computing. They propose to use the Pacman package as a first implementation of SEC; (b) Effective Resource Allocation (RA): a lack of grid-level mechanisms for controlling allocation of resources will cause grids to become difficult to manage and inefficient for typical users as the grids scale up in size. The solution proposed is to introduce a common grid currency to bootstrap an economy and promote policy decisions. Both SEC and RA require new approaches in order to achieve a qualitative leap forward in grid computing and in IT. Definitive solution of these problems would be a major intellectual advance in IT providing both theoretical understanding and practical tools that would be the basis of further research. Broad Impact: By identifying and unblocking the essential problems in contemporary grid computing, this work will enable grids to grow in size towards limits that we are not currently able to calculate. A dramatic growth in grids will result in near SETI-at-home scale computing for broad ranges of scientific and other computing projects and would constitute a true change in the national computing landscape.

该ITR提案是为了解决大型网格计算的两个关键缩放问题的要求。 具有当前已部署的网格系统的经验清楚地表明，尽管这些系统对于数十个站点是实用的，但具有数十全职经理，但它们并未扩展到大型科学合作或更大的全球规模所需的数百或数千个站点。 这两个基本的非缩放效果是：（a）软件环境计算（SEC）：缺乏定义明确的机制，用于可靠，安全且没有人为干预的远程站点上构建和操纵软件环境是非降低行为的主要来源。 提出的解决方案是定义和实施一个基础架构，其中软件环境创建和操纵是网格计算的基本要素。他们建议将PACMAN软件包作为SEC的首次实施； （b）有效的资源分配（RA）：缺乏控制资源分配的网格级机制将导致网格变得难以管理，并且对于典型用户而言，随着电网的规模扩大，典型用户的效率低下。 提出的解决方案是引入一种通用的网格货币来引导经济并促进政策决策。 SEC和RA都需要新的方法，以实现网格计算中的定性飞跃。 这些问题的确定解决方案将是它提供理论理解和实用工具的重大智力进步，这将是进一步研究的基础。 广泛的影响：通过识别和解除当代网格计算中的基本问题，这项工作将使网格能够朝着我们目前无法计算的限制的尺寸增长。 网格的急剧增长将导致大量科学和其他计算项目的近乎设定的规模计算，并将构成国家计算领域的真正变化。
