Following the initial benchmark, we have chosen to use the ClearSpeed Accelerator. With some smart quant re-engineering, we have further optimized the Distributed MC algorithm for pricing Bermudan Swaption to exploit the potential of distributed-based architecture. We will show the comparative benchmark results of the MC algorithm on ClearSpeed Accelerator, Cell and FPGA platform for the first time within our industry based on my working notes from my time in Barclays Capital London.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125485479","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 search engine is an important tool for users to access online video, resulting in considerable traffic on the video websites. In this work, we statistically analyze the video access log provided by a large scale video search engine, and validate that the aggregated views of online video from the search engine is diurnally regular. Furthermore, we find the probability of abrupt surge or disappearance of views is significantly high, having a percentage of 20% all videos. The results also show that 30% of them are spike that indicates that an accessing surge of views is followed by an immediate and abrupt falling. Such a result renders the big challenge how the website providers can satisfy the quality of service in providing their videos to users during the surging period. The online video access also indicates the social behaviors of the corresponding social group. These results are revealed by studying the querying string at the search engine. These results can be useful for the website developer to optimize the video system by allocating appropriate system resources according to the accessing habits of the users.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127837839","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}

Yet, battery and electronics technology has not followed this development as well, which has resulted in a situation where a mobile user's battery can only enable a few hours of active use. Therefore, we need to focus increasingly on energy efficient wireless and mobile communication to reduce energy consumption, but also to cut down greenhouse emissions and improve business competitiveness. Due to significant energy consumption of transmitting data over wireless networks, data compression techniques are one simple way to trade the overhead of compression for less communication energy. This paper investigates the usages of data compression to reduce the energy consumption in a modern hand-held device. By conducting various experiments, we analyze content-aware compression schemes that can reduce energy consumption significantly. Yet, blind or careless use of compression results in a huge energy loss. We also discuss the deployment issues of data compression.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133422809","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}

In these networks, the Medium Access Control (MAC) protocols are responsible for coordinating the access from active nodes into the acoustic channel, which is characterized by high propagation delay and low data rate, which is challenging for system synchronization, energy consumption and network output. Most researches in MAC protocol used for UASNs adopt collision avoidance mechanism with handshaking methods at present. But the long acoustic propagation delay results in low throughput and poor energy efficiency. In this paper, we propose a new amendment-based TDMA slot allocation mechanism, which is named WA-TDMA. Slot allocation starts from the node which launched as the center outward to form the wave-like proliferation and the slot allocation and amendment are continuously, which like the performance of wave. This can shorten the initialization time of the network. With the help of amendment, protocol can adjust slot usage to improve slots utilization and deal with slots reuse problem. The main function of the amendment is to avoid the slot collision, and improve the efficiency of slot using. The key characteristic of our mechanism is that it deals with holistic slot allocation problem well, and improve the slots utilization with certain protect distance at the same time.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134353536","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}
