One of the key features of our system is a modified snoop cache protocol to reduce overheads on the transactional memory consistency control. By publishing all of modified data in a transaction at once when the transaction commits, our system avoids the overhead on the commit, which would arise from a sequential publication (or write-back to main memory) of each data item in the transaction otherwise. Another feature is a virtualization of a cache layer in the memory hierarchy. When a cache must replace a line which contains speculatively modified data, our system dynamically reallocates the address of the line to another location in main memory, and back up the evicted data to a lower layer cache or main memory. The backed-up data is still under the control of the transactional memory consistency through our snoop cache protocol. By enlarging a cache capacity virtually in this manner, our system can support unbounded transactions which are not limited by the hardware resources in the size and the duration.","PeriodicalId":432222,"journal":{"name":"2014 IIAI 3rd International Conference on Advanced Applied Informatics","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127725103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-volatile main memory makes it possible to integrate secondary storages in main memory. The integration enables to reduce I/O to slow block devices. It is, however, impossible to construct large capacity main memory with a single NVM in this point. It is required to combine DRAM and NVM or combine NVM and another NVM to construct unified non-volatile main memory. The previous researches discussed NVM/DRAM hybrid main memory architecture, which combine PCM and DRAM. In our previous work, we proposed a method to manage NVM/DRAM hybrid main memory with programming language runtimes supports. Language runtimes, such as Java runtimes, have more detailed informaion about write acceess to data than operating system has. The language runtime supports are useful to manage NVM/DRAM hybrid memory therefore. In the proposed method, the runtime migrates objects between NVM and DRAM based on the characteristics of write access. The language runtime executes the migration processes during garbage collection processes. The performance of the proposed method rely on the frequency of garbage collection. In this paper, we will discuss and do an experiment about how the frequency of garbage collection effects the performance of the proposed method. The results of the experiment shows that the improved method cut 91 percent of write access. The results also show that the improved method cut 50 percent of the usage of DRAM.","PeriodicalId":432222,"journal":{"name":"2014 IIAI 3rd International Conference on Advanced Applied Informatics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133241029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Usually, negotiation problems have constraints, such as a complex and unknown opponent's utility in real time or time discounting. In the class of negotiation with constraints, effective automated negotiation agents can estimate their opponent's model depending on the proposals of their opponents and the negotiation scenarios. Recently, the attention of this study has focused on interleaving learning with negotiation strategies from past negotiation sessions. By analyzing such previous sessions, agents can estimate their opponent's utility function based on exchanging bids. In this paper, we propose an automated agent that estimates its opponent's strategies based on past negotiation sessions. Our agent decides the estimated values of its opponent using effective weighted functions based on the negotiation time. By using the estimated values of each issue, our agent can calculate its opponent's utility. In addition, we employ the estimated method proposed in this paper to the compromise strategy, which is the agent of the basic strategy of our proposed agent. In our experiments, we compared seven different weighted functions to determine the most effective one. In addition, we demonstrated that our proposed agent has better outcomes and a greater search technique for the Pareto frontier than existing ANAC2013 agents. We also compared our proposed agent and the basic compromising strategy.","PeriodicalId":432222,"journal":{"name":"2014 IIAI 3rd International Conference on Advanced Applied Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130318457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cost of establishing a new customer is five times more than maintaining an old one. As a result, to explore the investors choose continuous usage behavior of online security trading system as reference for security industry to promote and improve relevant business in the future. The model of this study is developed by combining DeLone and McLean's Information System Success Model (D&M IS Success Model) and Technology Acceptance Model (TAM). The variable of \"Habit\" was collected from \"Focus Group\" to develop research model. This research consists of 340 valid samples who using domestic opened and operative ones of security e-trade accounts. Then we apply \"Structural Equation Modeling\" to analyze the data and test hypothesis. Depending on the analysis of real evidences, this study have four conclusions: 1. In overall model, according to exogenous variables, \"Habit\" is the most effective to \"Continuous Usage Behavior\" of online stock trading, and followed by \"System Quality\". It reveals that \"Habit\" have greatly influence on \"Continuous Usage Behavior\". 2. In three quality contents, \"System Quality\" is the most important factor affecting \"Continuous Usage Behavior\", it is also the only significant factor affecting \"Perceived usefulness\" and \"User Satisfaction\", it shows \"System Quality\" is the major requirement of continued users. 4. We demonstrate that not only \"User Satisfaction\" positively affects \"Using Intention\" and further affects \"Continuous Usage Behavior\" in this study, but also the most important discovery is \"Habit\" positive affects \"Using Intention\" and further affects \"Continuous Usage Behavior\".","PeriodicalId":432222,"journal":{"name":"2014 IIAI 3rd International Conference on Advanced Applied Informatics","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133716676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
