通过分析目前几种虚拟计算环境的现状、特点及适用范围,针对中小规模、异构零散的的计算需求,提出一种基于框架技术的虚拟计算环境的实现方法,并结合框架技术设计了分层服务模型.基于复杂多样的、性能差距明显的计算资源的调度问题,提出了一种基于对等模式的随机自适应调度算法.该算法提供对关联任务的调度,适合异构的、资源规模较大的环境,尤其是计算资源差异明显的异构计算环境.实现了基于框架技术的虚拟计算原型系统,并通过实验测试对比算法的调度性能,最后将计算环境应用于实际的地震资料处理中.

By analyzing the current situation of serveral virtual environments, characteristics and scope of application, This paper de- signs and implements a framework-based virtual computing environment for small and medium-sized,heterogeneous fragmented com- puting needs, presents a hierarchical service design to improve service scalability and flexibility, and proposes a peer-to-peer mode ran- dom adaptive scheduling algorithm for the diverse complicated performance gap between computing resources scheduling problems. This algorithm supports to scheduler related task. the algorithm is applicable to heterogeneous and larger resource environment, particu- larly on the computing resources performance difference. The paper builds a prototype system and implement experiment, Finally, the computing environment is used in the actual seismic data processing.
