With the increasing demand for dynamic and customised resource provisioning for computational experiments in e-Science, solutions are required to mediate different participants’ varied demands for such resource provision. This paper presents a novel negotiation protocol based on a new collaboration model. The protocol allows e-Scientists, the manager of an e-Scientist’s collaboration, and resource providers to reach resource provisioning agreements. By considering the manager of an e-Scientist collaboration for negotiation decisions, the protocol enables fine-grained accountable resource provision on a per job basis for e-Scientist collaborations, without binding the e-Scientist collaboration to resource providers. A testbed built with the protocol is also presented, making use of a production e-Science gateway, use cases, and infrastructures. The testbed is experimentally evaluated, via designed scenarios and comparison with existing production tools. It demonstrates that the proposed negotiation protocol can facilitate accountable resource provision per job, based on resource sharing rules defined and managed by e-Scientist collaborations.

随着对电子科学中计算实验的动态和自定义资源供应的需求不断增长，需要解决方案来调解不同参与者对这种资源供应的不同需求。本文提出了一种基于新协作模型的新颖协商协议。该协议允许电子科学家，电子科学家协作的管理者和资源提供者达成资源供应协议。通过考虑电子科学家协作的经理进行谈判决策，该协议可以在每个工作的基础上为电子科学家协作提供细粒度负责的资源提供，而无需将电子科学家协作绑定到资源提供者。还介绍了使用该协议构建的测试平台，其中利用了生产电子科学网关，用例和基础架构。通过设计方案并与现有生产工具进行比较，对试验台进行了实验评估。它表明，基于由e-Scientist合作定义和管理的资源共享规则，所提出的协商协议可以促进每个工作的负责任的资源提供。
