Big data as a paradigm focuses on data volume, velocity, and on the number and complexity of various data formats and metadata, a set of information that describes other data types. This is nowhere better seen than in the development of the software to support next generation astronomical instruments including the MeerKAT/KAT-7 Square Kilometre Array (SKA) precursor in South Africa, in the Low Frequency Array (LOFAR) in Europe, in two instruments led in part by the U.S. National Radio Astronomy Observatory (NRAO) with its Expanded Very Large Array (EVLA) in Socorro, NM, and Atacama Large Millimeter Array (ALMA) in Chile, and in other instruments such as the Large Synoptic Survey Telescope (LSST) to be built in northern Chile. This chapter highlights the big data challenges in constructing data management systems for these astronomical instruments, specifically the challenge of integrating legacy science codes, handling data movement and triage, building flexible science data portals and user interfaces, allowing for flexible technology deployment scenarios, and in automatically and rapidly mitigating the difference in science data formats and metadata models. The authors discuss these challenges and then suggest open source solutions to them based on software from the Apache Software Foundation including Apache Object-Oriented Data Technology (OODT), Tika, and Solr. The authors have leveraged these solutions to effectively and expeditiously build many precursor and operational software systems to handle data from these astronomical instruments and to prepare for the coming data deluge from those not constructed yet. Their solutions are not specific to the astronomical domain and they are already applicable to a number of science domains including Earth, planetary, and biomedicine.
GeoBase
Authors: Malik Tanu
Published: September 2013

Data-rich scientific disciplines increasingly need end-to-end systems that ingest large volumes of data, make it quickly available, and enable processing and exploratory data analysis in a scalable manner. Key-value stores have attracted attention, since they offer highly available data storage, but must be engineered further for end-to-end support. In particular, key-value stores have minimal support for scientific data that resides in self-describing, array-based binary file formats and do not natively support scientific queries on multi-dimensional data. In this chapter, the authors describe GeoBase, which enables querying over scientific data by improving end-to-end support through two integrated, native components: a linearization-based index to enable rich scientific querying on multi-dimensional data and a plugin that interfaces key-value stores with array-based binary file formats. Experiments show that this end-to-end key-value store retains the features of availability and scalability of key-value stores and substantially improves the performance of scientific queries.

Authors: Nambiar Raghunath , Poess Meikel
Published: September 2013

Industry standard benchmarks have played, and continue to play, a crucial role in the advancement of the computing industry. Demands for them have existed since buyers were first confronted with the choice between purchasing one system over another. Over the years, industry standard benchmarks have proven critical to both buyers and vendors: buyers use benchmark results when evaluating new systems in terms of performance, price/performance, and energy efficiency; while vendors use benchmarks to demonstrate competitiveness of their products and to monitor release-to-release progress of their products under development. Historically, we have seen that industry standard benchmarks enable healthy competition that results in product improvements and the evolution of brand new technologies. Over the past quarter-century, industry standard bodies like the Transaction Processing Performance Council (TPC) and the Standard Performance Evaluation Corporation (SPEC) have developed several industry standards for performance benchmarking, which have been a significant driving force behind the development of faster, less expensive, and/or more energy efficient system configurations. The world has been in the midst of an extraordinary information explosion over the past decade, punctuated by rapid growth in the use of the Internet and the number of connected devices worldwide. Today, we’re seeing a rate of change faster than at any point throughout history, and both enterprise application data and machine generated data, known as Big Data, continue to grow exponentially, challenging industry experts and researchers to develop new innovative techniques to evaluate and benchmark hardware and software technologies and products. This chapter looks into techniques to measure the effectiveness of hardware and software platforms dealing with big data.

A New Wavelet-Based Compressive Sensing for Image Compression
Authors: Jiang Wei , Yang Jun Jie
Published: September 2013

Compressive sensing (CS) technique can capture and represent compressible signal at a rate below the Nyquist rate of sampling. In this paper, the compressive sensing principles are studied and a new wavelet-based coding method is proposed. Two-dimentional discrete wavelet transform (DWT) is applied for sparse representation. Then the wavelet coefficients are divided into four blocks and are compressed by four different sensing matrixes respectively. The recovery quality depends on the number of received CS measurements. Experimental results show that the proposed coding method achieving higher performance compared with the conventional wavelet-based compressive sensing coding system. With 50% coefficients retained, the image can still be recovered with considerably objective and subjective quality.

In order to meet the user requirement of the dynamic customization and configuration of the changeable and complicated page functionality on the client, when constructing the web application platform, an advanced rich-client method and technology based on DOM ( Document Object Model ) was designed and used to develop the client module. The client module with rich-client technology was in the traditional J2EE (Java 2 Enterprise Edition ) architecture which was the Client-Centric and MVC ( Model-View-Control ) mode. On the client side, according to the dynamic page generation algorithm, developers wrote JavaScript scripting language based on DOM and Ajax (Asynchronous JavaScript and XML) for user customization and choose the part of the third-party open-source Extjs ( Extendable JavaScript ) components as the page elements to generate client-side dynamic configuration interface. From a user experience perspective, The good performance test results of the advanced rich-client method effectively examine the distinguishing features of the new method.
An Improved MapReduce Model for Computation-Intensive Task
Authors: Sun Han Lin
Published: September 2013

MapReduce is a widely adopted parallel programming model. The standard MapReduce model is designed for data-intensive processing. However, some machine learning algorithms are computation-intensive and time-consuming tasks which process the same data set repeatedly. In this paper, we proposed an improved MapReduce model for computation-intensive algorithms. The model is constructed from a service combination perspective. In the model, the whole task is divided into lots of subtasks taking account into the algorithms parameters, and the datagram with acknowledgement mechanism is used as the communication channel among cluster workers. We took the multifractal detrended fluctuation analysis algorithm as an example to demonstrate the model.
