摘要

试点任务支持有效的分布式资源利用,并且可以说是最广泛使用的分布式计算抽象之一——通过使用它们的应用程序的数量和类型以及支持它们的生产分布式网络基础设施的数量来衡量。尽管试点工作被广泛采用,但并不存在一个定义良好、统一的试点工作概念模型,该模型可用于定义、比较和对比不同的实施。通常,试点作业实现与它们最初设计的分布式网络基础设施是强耦合的。这些因素对可扩展性和互操作性构成了障碍。本文试图(i)提供一个最小但完整的Pilot-Job模型(P*), (ii)通过将各种现有的和众所周知的Pilot-Job框架(如Condor和DIANE)映射到P*来建立P*模型的通用性,(iii)为P*模型(Pilot-API)派生一个可互操作和可扩展的API, (iv)通过在不同的生产分布式网络基础设施上同时使用多个不同的Pilot-Job框架来验证Pilot-API的实现。(v)将P*模型应用于试点数据。

P∗: A model of pilot-abstractions
Pilot-Jobs support effective distributed resource utilization, and are arguably one of the most widely-used distributed computing abstractions - as measured by the number and types of applications that use them, as well as the number of production distributed cyberinfrastructures that support them. In spite of broad uptake, there does not exist a well-defined, unifying conceptual model of Pilot-Jobs which can be used to define, compare and contrast different implementations. Often Pilot-Job implementations are strongly coupled to the distributed cyber-infrastructure they were originally designed for. These factors present a barrier to extensibility and interoperability. This paper is an attempt to (i) provide a minimal but complete model (P*) of Pilot-Jobs, (ii) establish the generality of the P* Model by mapping various existing and well known Pilot-Job frameworks such as Condor and DIANE to P*, (iii) derive an interoperable and extensible API for the P* Model (Pilot-API), (iv) validate the implementation of the Pilot-API by concurrently using multiple distinct Pilot-Job frameworks on distinct production distributed cyberinfrastructures, and (v) apply the P* Model to Pilot-Data.
