HPC4EAS member participation at the ICCS 2013 (Juny 5-7) – Barcelona.

The International Conference on Computational Science is an annual conference for researchers and scientists form different knowledge areas including (but not limited) to computer science, mathematics, life sciences, physics, chemistry, geology, etc is to say all applications areas who are pioneering in the utilization of computational methods in sciences as well as in arts and humanitarian fields, in order to discuss problems and solutions in the area, to identify new issues, and to shape future directions for research.

ICCS 2013 in Barcelona and is the thirteenth in this series of highly successful conferences http://www.iccs-meeting.org/iccs2013/

The first ICCS was in 2001 and has attracted increasingly higher quality and numbers of attendees and papers. The proceedings series have become a major intellectual resource for computational science researchers and serve to define and advance the state of the art of the field and the 30% high-quality papers for presentation at the conference and publication in the proceedings. These are published by Elsevier in their new Procedia Computer Science series and ICCS is an ERA 2010 A-ranked conference series.

Conference by Genaro Fernandes de Carvallo Costa, Associated Professor at Universidade Federal da Bahia, Brasil.

 Abstract: The daily social communication takes many forms of interaction. E-mails, tweets, text messages and social networks posts define the modern social lives of the individuals. And this information about the behavior can be collected, stored, and made available to researchers.

With access to billions of mails, tweets, and messages, is possible to build reliable models of social phenomena, like how the individuals choose their social partners o how a tweet spreads through a network.

There are many research projects with the objective of model human online behavior and find how it shapes social networks and how transform these patterns into a more general, abstract theory. Professor Costa present the working progress and results of the subject and remarkable ideas in this area.

Professor Costa is Associated Professor at UBBA and CEO at Convergence Works, PhD by UAB, and he has held positions of PostDoc at Federal University of Bahia, Postdoc at Universidade Federal da Bahia, Reseach Fellow at Universitat Autònoma de Barcelona, Manager at Telematic Company and CTO of Bahianet Internet e Serviços.

A proposal from Professor Luque, Mr. Taoboada and Dr. Valero  was accepted for a grant award by IBM’s in the framework of Smarter Cities project.

IBM considers that a Smart cities know how to transform their systems and optimize the use of largely finite resources. To help drive efficiency and increase effectiveness, they leverage technology to make systems instrumented, interconnected and intelligent

1. Instrumentation, or digitization, means that the workings of that system are turned into data points and the system is made measurable.
2. Interconnection means that different parts of a core system can be joined and “speak” to each other, turning data into information.
3. Intelligence refers to the ability to use the information created, model patterns of behavior or likely outcomes and translate them into real knowledge, allowing informed actions.

To help these objectives, the project led by IBM offers a set of services, tools and collaboration working groups that facilitate and will enable smart cities can become a reality (http://smartercitieschallenge.org/)

The proposal presented by this group include the following objectives:

1. Research activities: Introduce HPC and Advanced Simulation in the Management and Optimization of Health Services.
   Exploit the possibilities opened by this research field developing, in cooperation with IBM, powerful tools such as Decision Support Systems (DSS), for smarter management in the health services area.
2. Teaching activities: Introducing Advanced Simulation and Health Services management in the Computer Science and Services degree.
   Increasing the IBM cooperation, as an educational partner, in the areas of HPC and services for the student of the CS&S degree.

Federated Cloud Computing: Power-Aware Solutions and Applications
Abstract: Cloud computing is a recent paradigm for provision of computing infrastructure, platform and/or software in the Internet, which aims to reduce costs. One important factor in the operational cost of cloud data centers comes from the power consumed by the computational resources. Many studies have been conducted to provide power reduction but most of the proposed techniques incur in a great slowdown of the applications. In this talk, I will first address aspects of Cloud Computing and Green Computing. Then, I will present our server consolidation strategy for Federated Cloud systems. I will also show you some simulation results that show that our collaborative strategy is able to reduce more than 50% of energy consumption, while still meeting the Quality-of-Service requirements. After that, I will present one strategy to run a huge Bioinformatics application on Federated Public Clouds. Finally, I will present the conclusions and future directions.
