These datasets can range from satellite imagery to citizen scientist observations, and include both publicly available and proprietary resources. The traditional mode of work is for each participant to have their own desktop machine with large attached storage and to essentially work in a silo. This approach, however, inhibits effective collaboration because individuals must navigate a complex system setup and use ad-hoc techniques such as sharing a portable hard drive to co-produce data products. The limitation of running on a desktop computer also restricts the scale of questions that can be asked due to excessively long processing times, sometimes spanning several weeks. Another consequence of this process is the lack of data conformance standards, that tend to emerge from shared needs when communities collaborate to advance application frameworks.In this paper, we investigate the social and collaborative aspects of cloud architectures to support geospatial computing. These new architectures provide emergent modes of collaboration. We provide a concrete case study of a typical geospatial collaboration, and detail the build of a collaborative platform as we evolve it from a silo, to a research cluster, and finally to a public cloud. The architectures are evaluated in terms of costs and benefits from systems and software engineering perspectives.","PeriodicalId":152556,"journal":{"name":"2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134163216","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}

Adaptive Clock and Data Recovery for Asymmetric Triangular Frequency Modulation Profile 非对称三角形调频配置文件的自适应时钟和数据恢复

With high data rates, the effect of Electromagnetic Interference (EMI) is increased. Several spreading spectrum profiles are able to reduce the effect of EMI. Asymmetric spreading spectrum profile is one of the types that can be implemented easily and can make a significant reduction on EMI. The challenge in CDR design is increased with asymmetric spreading profiles as the slew-rate is high with respect to the other profiles. Many researches provided several architectures for adaptive CDR with symmetric spreading profiles. In this research, a new architecture is proposed to detect the large phase error to reach suitable CDR controller parameters needed to recover the clock with high slew-rate profiles. The proposed architecture is able to get locking with the incoming data in short-time even with an initial large difference between transmitter and receiver clock frequency and at the same time achieve minimum jitter. A white Gaussian noise with 30 dB Signal to Noise Ratio (SNR) is used on a channel model to simulate the actual behavior on SIMULINK. Also, a search algorithm is proposed to find the best CDR settings in the proposed architecture. Results obtained from MATLAB shows the efficiency of the proposed architecture to track the data with largest slew-rate using sudden step change on transmitter clock frequency.","PeriodicalId":152556,"journal":{"name":"2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129539588","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}

Does the ISA Really Matter? A Simulation Based Investigation ISA真的重要吗?基于仿真的调查

However, the extremely diverse hardware implementations make the comparisons among different platforms difficult and indirect, not mention the difficulties of the analyses of micro-architectural metrics. In this paper, we conduct an investigation of ARM, RISC-V and X86 ISAs based on the gem5 cycle-accurate simulations, in which the target implementations of these ISAs are simulated with the same three hardware configurations, namely the In-Order, Out-of-Order1 and Out-of-Order2. Fifteen benchmarks chosen from SPEC2006 and BEEBS are used to conduct the simulations. Meanwhile, the power and energy consumption of the target implementations is evaluated by McPAT. Our simulation results suggest that although ARM ISA outperforms RISC-V and X86 ISAs in performance and energy consumption, the differences between ARM and RISC-V are very subtle, while the performance gaps between ARM and X86 are possibly caused by the relatively low hardware configurations used in this paper and could be narrowed or even reversed by more aggressive hardware approaches. Our study confirms that one ISA is not fundamentally more efficient.","PeriodicalId":152556,"journal":{"name":"2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129824925","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}

It enables users to drill down or roll up from a level to another level in a dimension, which forms an analytical path/thread. In many scenarios, this analytical path is very useful for users to keep their analysis in context. But most visualization tools display only the result in one chart after drilling down or rolling up. The analytical context or the intermediate process is lost or indirect. This paper presents a novel OLAP visualization approach called TAVO - a Tree-like Analysis View for OLAP. It visualizes the multi-dimensional data by various charts and organizes them in a tree, where each node is a chart and connects other charts when a user navigates along a dimension by levels or to another dimension. By this way, the drill-down/roll-up semantic relationship is clearly expressed. Users can easily explore relative history queries by rolling up in a chart. We implemented TAVO by dynamically generating multidimensional expressions (MDX) on the fly and then visualizing the results by visualization components such as Microsoft Office Web Component. The system prototype demonstrates the effectiveness of TAVO.","PeriodicalId":152556,"journal":{"name":"2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116904400","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}
