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.

Research in Cyber Security

The security team led by Prof. Barton Miller at the University Wisconsin is working on several areas of research that we describe during talk. The first area is the analysis, monitoring, and control of malicious programs. The research is based on a hybrid static/dynamic technique that monitors known code in a binary, and then discovers new code as it is decoded, unpacked, and modified, guaranteeing that we can monitor and control the code before it is executed. This research is being incorporated in the Dyninst binary instrumentation tool suite. The second area is the use of advanced machine learning techniques to expose the provinance of binary programs. These techniques can report the source language(s) in which the program was written, the compiler used and the optimization level. In addition, we can also identify the author of the program solely from the binary code. The last area of research is our joint work with the Autonomous University of Barcelona on the in-depth vulnerability assessment of middleware and services. The work at Wisconsin includes a technique called self-propelled instrumentation, that can be injecting into a running program and trace its behavior, and propagate this tracing in other processes, even on other hosts.

Conference by Dr Mauricio Marin, Yahoo! Labs Santiago Researcher, Professor at Universidad de Santiago, Chile

Abstract: Large scale Web search engines are complex and highly optimized systems devised to operate on dedicated clusters of processors. Any, even a small, gain in performance is beneficial to economical operation given the large amount of hardware resources deployed in the respective data centers. Performance is fully dependent on users behavior which is featured by unpredictable and drastic variations in trending topics and arrival rate intensity. In this context, discrete event simulation is a powerful tool either to predict performance of new optimizations introduced in search engine components or to evaluate different scenarios under which alternative component configurations are able to process demanding workloads. These simulators must be fast, memory efficient and parallel to cope with the execution of millions of events in small running time on few processors. We propose achieving this objective at the expense of performing approximate optimistic parallel discrete-event simulation.

Raising to the clouds by Eduardo Argollo (Research Scientist HP Exascale Computing Lab, Sant Cugat del Valles)

Eduardo Argollo is Research Scientist at HP Labs since 2007 (Computer Science MS degree in 1997, Catholic University of Salvador, in Brazil, PhD in Computer Science from the University Autonoma of Barcelona, in Spain)

Eduardo has more than 10 years of experience in the ERP systems, databases and data warehousing development. Prior to joining HP, he was worked in methodologies to efficiently attain high-performance from a collection of internet-connected geographically distributed multi-clusters and in the CoreGRID Network of Excellence in Passau, Germany. In this work was involved in the automatic parallelization of applications using higher-order Grid components.

His current research interests include system-level simulation, virtualization and parallel computing middleware.

Researchers of the our group (HPC4EAS) in collaboration with the team at the Emergency Services Unit at Hospital de Sabadell (Parc Taulí Healthcare Corporation), have developed an advanced computer simulator to help in decision-making processes (DSS, or decision support system) which could aid emergency service units in their operations management.

The model was designed based on real data provided by the Parc Taulí Healthcare Corporation, using modelling and simulation techniques adapted to each individual, and which require the application of high performance computing. The system analyses the reaction of the emergency unit when faced with different scenarios and optimises the resources available.

Researchers defined different types of patients according to their emergency level, and doctors, nursing teams, and admissions staff according to different levels of experience. This permitted studying the duration of processes such as the triage (when the emergency level is determined), the number and type of patients arriving at each moment, the waiting period for each stage or phase of the service, costs associated with each process, the amount of staff needed to determine a type of assistance and, in general, all other quantifiable variables. The system not only helps to make decisions in real time, it also can help by making forecasts and improving the functioning of the service.
