A spatially triggered dissipative resource distribution policy for SMT processors

Programs take on changing behavior at nmtime in a simultaneous multithreading （SMT） environment. How reasonably common resources are distributed among the threads significantly determines the throughput and fairness performance in SMT processors. Existing resource distribution methods either mainly rely on the front-end fetch policy, or make distribution decisions according to the limited information from the pipeline. It is difficult for them to efficiently catch the various resource requirements of the threads. This work presents a spatially triggered dissipative resource distribution （SDRD） policy for SMT processors, its two parts, the self-organization mechanism that is driven by the real-time instructions per cycle （IPC） performance and the introduction of chaos that tries to control the diversity Of trial resource distributions, work together to supply sustaining resource distribution optimization for changing program behavior. Simulation results show that SDRD with fine-grained diversity controlling is more effective than that with a coarse-grained one. And SDRD benefits much from its two well-coordinated parts, providing potential fairness gains as well as good throughput gains. Meanings and settings of important SDRD parameters are also discussed.     

A three-level mobility management scheme for hierarchical mobile IPv6 networks

INTRODUCTION Mobile IPv6 (MIPv6) (Johnson et al., 2004) was proposed to maintain network connectivity in the next generation Internet. However, communication quality of MIPv6 degrades because of the high signaling overhead and the long signaling delay when a mobile node (MN) performs handover. Hierarchical Mobile IPv6 (HMIPv6) (Soliman et al., 2005) was proposed to improve the performance of MIPv6, where the Mobility Anchor Point (MAP) handles mobility in- side the local domain…     

公民参与机制与我国的社会建设

公民参与水平是社会建设质量和水平的重要体现。推进我国社会快速、健康、和谐发展，需要扩大公民有序的政治参与。在推进社会建设中加快政府职能转换，强化制度性建设以保障公民有效参与，从基层民主建设做起实现公民充分参与，是当前我国公民参与机制建设的重要课题。     

澳大利亚体育政策转型对我国体育发展的启示

运用文献资料法和逻辑分析法,对新世纪以来澳大利亚体育发展所面临的挑战及体育政策进行分析。研究认为澳大利亚在高水平竞技体育领域、大众体育领域、女子体育领域、土著居民体育领域和残疾人体育领域面临重要挑战,这也是新世纪以来澳大利亚体育政策制定的基本出发点。此外,澳大利亚体育政策的转型特征表现为:体育政策纲要的结构更富层次性和衔接性;体育政策的具体措施更加细化,并且更富针对性、明确性和可操作性。最后,指出了澳大体育发展的挑战及政策转型给予我国体育政策发展的一些启示。     

自由是干预的目的——重温李斯特的国家干预理论

干预的制度前提是国家立足于自由经济机制的社会根基,国家能够自觉职守社会公共利益,保持高尚的理性道德身份,拥有高于社会或个人的理性与能力;或能够接受法律对自身的约束,使其能以社会公共利益作为行为约束底线。国家经济运作的模式是社会掌控物资资本,国家掌控精神资本,前者生产物质,后者生产生产力,精神资本决定物质资本,精神资本在国家生产力中居于绝对超越物质资本的优胜地位。自由与生产事业两者总是分不开的,干预必须限定在实现自由目标的框架内,干预是实现自由的手段,自由是干预的目的。
