SCOPE OF THE CONFERENCE
-----------------------

In recent years, we have witnessed data explosion driven by new types of applications and devices; petabyte-scale archives are no longer a rare occurrence. Even traditional application domains have become data intensive. Fostering capabilities to extract value from large data sets is no longer the problem and desire of the big companies alone; government agencies, small and medium-sized enterprises and even individuals perceive value in data. Among other things, this shift is driven by the cost, scalability and availability benefits coming with the emergence and rapid adoption of cloud computing and massively parallel processing paradigms. Thus, access to large-scale computing facilities is no longer the main concern. Instead, access to data, integrating data silos across multiple domains and means to extract value from data become the key issues.

The analysis of massive data sets, commonly referred to as Big Data, is an important and challenging task as it reveals trends or patterns in the data including associations, correlations and/or exceptions. Such information is needed in order to turn collected data into knowledge. Visual analytics and visualisation techniques have been proven to be of great value in analysing and exploring large data sets. Interactive, graphical forms of data presentation can fosters new insights, enable the formation and validation of new hypotheses, and lead to better problem solving and knowledge extraction approaches. However, traditional visualisation methods (most of which have been developed 10 or more years ago) often cannot convey useful information to people because of limited canvas space and people's perception capabilities. Human perception (i.e., the precision of the eye and the ability of the human mind to process visual patterns) limits the number of perceptible pixels and therefore affects visual scalability directly; while canvas space or monitor resolution affects visual scalability. There is a need for a serious evaluation of existing techniques, or even, a proposal of a new paradigm of visualisation techniques. Such techniques must better enable humans to efficiently spot, interpret, and gain knowledge from extremely large data sets; that is, insights that may even be missed by large computation efforts in current data analytics techniques.

The CloudVis 2011 workshop will bring together researchers and practitioners from the areas of data visualisation, computer graphics, cloud / high-performance computing, and data-driven analytics. It aims to facilitate the exploration of using / combining approaches across domains in order to create effective visualisations techniques for which big data, intensive data analytics and high performance computing requirements are a necessity.
