Selected papers will be invited to special issues of CGC2012 in Concurrency and Computation: Practice and Experience, Future Generation Computer Systems and International Journal of High Performance Computing Applications. Introduction: Big data is an emerging paradigm applied to datasets whose size is beyond the ability of commonly used software tools to capture, manage, and process the data within a tolerable elapsed time. Such datasets are often from various sources (Variety) yet unstructured such as social media, sensors, scientific applications, surveillance, video and image archives, Internet texts and documents, Internet search indexing, medical records, business transactions and web logs;and are of large size (Volume) with fast data in/out (Velocity). Various technologies are being discussed to support the handling of big data such as massively parallel processing databases, scalable storage systems, cloud computing platforms, and MapReduce. MapReduce is a distributed programming paradigm and an associated implementation to support distributed computing over large datasets on cloud. This workshop aims at providing a forum for researchers, practitioners and developers from different background areas such as cloud computing, distributed computing and database area to exchange the latest experience, research ideas and synergic research and development on fundamental issues and applications about big data and MapReduce in cloud environments. The workshop solicits high quality research results in all related areas. Topics: The objective of the workshop is to invite authors to submit original manuscripts that demonstrate and explore current advances in all aspects of big data and MapReduce. The workshop solicits novel papers on a broad range of topics, including but not limited to: · Big Data theory, applications and challenges · Recent development in Big Data and MapReduce · Big Data mining and analytics · Big Data visualization · Large data stream processing on cloud · Large incremental datasets on cloud · Distributed and federated datasets · NoSQL data stores and DB scalability · Big Data sharing and privacy preserving on cloud · Security, trust and risk in Big Data · Big Data placement, scheduling, and optimization · Extension of the MapReduce programming model · Distributed file systems for Big Data · MapReduce for Big Data processing · MapReduce on hybrid cloud · MapReduce on heterogeneous distributed environments · Performance characterization, evaluation and optimization · Simulation and debugging of MapReduce and Big Data systems and tools · Security, privacy, reliability, trust and privacy in MapReduce · Volume, Velocity and Variety of Big Data on Cloud · Multiple source data processing and integration with MapReduce · Resource scheduling and SLA for MapReduce · Big Data processing tools based on MapReduce · Storage and computation management of Big Data · Large-scale scientific workflow in support of Big Data processing on Cloud General Chairs: Geoffrey Charles Fox, Indiana University, USA Xian-He Sun, Illinois Institute of Technology, USA Jian Pei, Simon Fraser University, Canada Program Chairs: Xuyun Zhang, University of Technology Sydney, Australia Suraj Pandey, CSIRO, Australia Xiaolin Li, University of Florida, USA Jinjun Chen, University of Technology Sydney, Australia Any enqueries, please direct to Xuyun Zhang at xyzhanggz@gmail.com or xuyun.zhangcs@gmail.com
