Allocation order is the best for locality, which slide mark compact algorithm is based on. But traditional design made the algorithm's overhead too large. We proposed a fast slide mark compact algorithm, which reduces the overhead by mark bit table, live block pool and offset table. The results show that it achieves up to 8.9% speedup in industry-standard benchmark SPEC JVM98 on the Pentium 4, 11% improvement in dtlb miss numbers and 13.6% reduce with L2 cache miss numbers.

The characteristics of advanced integrated circuit technologies require architects to look for new ways to utilize large numbers of gates and mitigate the effects of high interconnect delays. Chip multiprocessors (CMPs) exploit increasing transistor counts by placing multiple processors on a single die. As the chip multiprocessors (CMPs) have become the trend of high performance microprocessors, the target workloads become more and more diversified. Due to the wire delay problem and diversity of applications, neither private nor shared caches can provide both large capacity and fast access in CMPs. A novel CMP cache design, the heterogeneous CMP cache (HCC) is presented, in which chips are constructed by tiles of two different categories. L2 caches of private tiles provide lowest hit latency and L2 cache of shared tiles increases the effective cache capacity for shared data. Incorporating indirect-index cache technology to share capacity between different hierarchies, HCC provide a both capacity-effective and access-fast on-chip memory subsystem. Detailed full-system simulations are used to analyze the HCC performance for various programs, including SPEC CPU2000, SPLASH2 and commercial workloads. The result shows that HCC improves performance by 16% for single-threaded benchmarks and 9% for multi-thread benchmarks. HCC is easy to implement and the design ideas will be used in the future multi-core processors of Godson series.

Anomaly detection can detect unknown or new intrusions, and there are increasing interest in it. A normal network behavior model is necessary in any anomaly detection. Assuming that abnormal network behaviors are obviously different from normal ones, there should be some abnormal network packets that are obviously different from normal packets. Normal network packets are disassembled into binary strings whose lengths are l, and all the strings construct a set U-normal. The normal network behavior model is a set U-model. The length of each element in U-model is also l. U-model is made up of those elements each of which matches at least one element in U-model and doesn't match any other element in U-model. Normal network behaviors hide in U-model. The size of U-model is discussed. Experimental results indicate that abnormal network behaviors can feasibly be detected with U-model Further work is to construct a more feasible U-model to put into practice.

To efficiently and appropriately integrate daylighting strategies in their projects, building designers need reliable methods to address issues such as daily and seasonal variations or the balance between sufficient illumination with visual and thermal comfort aspects. This integration must also happen early in the design process to have a significant impact on energy savings and ultimate building performance. This paper proposes to address this need by fulfilling three major objectives: support the design process using a goal-oriented approach based on iterative design improvement suggestions;provide climate-based annual metrics in a visual and synthesized form;and relate quantitative and qualitative performance criteria thanks to a novel interface for browsing daylighting analysis data in various forms. A methodology to achieve these objectives is described here as the Lightsolve approach.

Since Japan is limited in area, the effective ocean space development is very important and urgent subject. Concerning a research and development of effective ocean space utilization, the MEGA-FLOAT was one of the most famous projects in Japan that had the purpose of a floating airport construction, and the numerous R & D were conducted aiming at actual construction and those results were reported in respect of conceptual design, construction method, fluid analysis, structural dynamic analysis, environment issue etc.. However, the end was faced without achieving it, it can be said that the effect is large. After the end of that project, the realistic, small or medium size structure began to be paid to attention. As the good example of such a kind floating structure, floating pier and disaster prevention base having an advantage against an(Figure Presented) earthquake, floating restaurant etc. were constructed shown in Figure 1. In this paper, assuming the small size floating restaurant, the wave response analysis was studied, and the habitability of that structure was evaluated from the response calculation results. Concretely, the floating base part;barge type of the restaurant building was designed by the Class NK (Rules and Guidance for the survey and construction of steel ships. Part Q Steel barges). The calculation model consists of a three-story building and the base, that floating artificial base supporting the building was assumed by the elastic plate structural system, and also that building was of the frame structure system. In order to structural analysis, the restaurant model of two different structural systems was united into one body system. In this paper, it is called the hybrid structural system. Fluid effect was analyzed as the fluid-structural interaction problem. Concretely, the Boundary Integral Equation Method (BIEM) was used here, and the wave response calculation was demonstrated by that forces. The evaluation of habitability of the restaurant
