中文摘要: 数据密集型计算已经成为重要的计算类型,但基于多核/众核新型体系结构,如何为其构建高效、低耗、可靠的运行时支撑环境是一个重要的挑战。运行时系统是系统软件的重要组成部分,是确保系统安全与高效的关键环节。本课题以多核/众核等新型体系结构为硬件支撑,围绕数据密集型计算所存在的运行时执行效率不高、可靠性保障不足、能耗高等突出问题,以实现程序运行时的高效性、高可靠、低能耗为目标,对其展开深入研究。课题围绕着四个方面开展:1)运行时资源监控与预测、映射及管理模型;2)运行时性能优化与调度机制;3)运行时能耗度量、预测模型与能耗敏感的调度算法;4)运行时线程级/虚拟机级容错模型和可靠性保证机制。基于上述四个相互关联的研究内容,实现典型数据密集型计算的运行时原型系统,以验证所取得关键技术和算法。本课题的成功研究将有助于促进和改善数据密集型计算在多核/众核环境上的运行效果,推动多核技术的进步。

英文摘要: Data-itensive computing is very important now in many areas. But, how to provide a runtime susyem with high efficiency, eneygy saving and good reliability based on multi/many-cores environment is still a key challenge. As we all know, runtime system is a key part of system software to ensure system's security and high efficiency. Based on the multi/many-cores environment, the project will solve the problems for data-intensive computing. There are four key issues in the project, which are listed as follows: 1) resource monitoring, predicting, mapping and scheduling in runtime system; 2) performance adjustment and scheduling in runtime system; 3) energy measurement, predicting and energy-aware scheduling; 4) fault-tolerant models for threads/virtual machines. Based on the four research issues, we will implement the runtime system prototype for data-intensive super computing systems to verify the correctness of the above key proposed schemes. The success of the research will improve the running effects of data-intensive computing application on multi/many-cores environment.
