Computation.

BIFI is one of the most relevant e-science centres in Spain, both as resource providers and as scientific end-users. Mainly composed by engineers and physicists, the Computing Area includes a large range of activities from technology research, user support, applied research, technology transfer and engagement.

BIFI hosts the Supercomputing Centre of Aragón (CESAR), a computing infrastructure covering a wide set of technologies: HPC (Distributed and Shared Memory), Grid, Cloud, Volunteer Computing and Dedicated Computers.

In fact, the Computing Area is structured in four research lines:

  • Citizen Science
  • Data Analysis, Advanced visualization and Software Development
  • High Performance Computing (HPC)
  • Grid and Cloud Computing
  • Special Purpose Computers

The HPC computing resources deliver several millions of CPU hours and hundreds of terabytes of storage per year, to both BIFI’s researchers (and their collaborators) and external users through the Spanish Supercomputing Network, the Hosted Clusters program and other services provided.

Also the grid&cloud infrastructures provide computing resources to a wide range of researches, who have specific or complementary requirements to those offered by the HPC infrastructures. In addition to this, they also serve as a testbed for Spanish and European companies and SMEs, which are willing to adopt these technologies to improve their business model. Therefore, in the last years, we have focused our cloud research and infrastructures in helping SMEs on how to take advantage of these powerful technologies.

In the research line of special purpose computers, we work on the design and construction of machines dedicated to solve very specific problems, like the awarded supercomputer JANUS, based on FPGAs and with relevant scientific results published.

BIFI is an international reference in citizen science activities and leads the volunteer computing project Ibercivis.

SUMMARY OF THE RESEARCH LINE

Citizen science is a research line that promotes the participation of society in science. The first project that emerged in this framework was Ibercivis, in which citizens may collaborate with basic research by sharing computational resources in their idle computer times.

Among the main objectives of this promising research line are to recognize the potential of citizen science and the role of society, as well as the importance of active participation of citizens in different activities of scientific nature. In recent years, contributions in this regard have been significantly increasing and have a great added value for researchers, in general. BIFI Institute supports and promotes this task, allowing citizens to make use of resources and computational infrastructure through different activities such as data analysis and the development of interesting experiments in diverse scientific fields. In this way, volunteers can engage in research and contribute to science.

Besides developing our own tools, citizen science projects and participatory experiments collaborating with researchers and citizens, the group has coordinated “Socientize”. This project proposed useful policy recommendations as an input for the strategy for Citizen or Public engagement in European science research activities in Horizon 2020. All these proposals are included in the White Paper on Citizen Science for Europe. Several Commission services (including DGs CONNECT, RTD and the JRC) are using this Paper as a reference document.

SUMMARY OF THE RESEARCH LINE

The development group belongs to the computing area at BIFI, and it is composed by two experienced computing engineers.

The main goal of this team is to research and support research when software development is involved. To achieve it, one of the most important tasks that we perform is the participation in research projects in which we collaborate with companies and other research groups. These collaborations are focused on different innovative topics such as BigData, Internet analysis, social networks, distributed computing, new technologies in education, etc. The collaboration levels go from small contributions to local companies/research groups to international projects such as FPVII.

The other task that we carry out at BIFI is to support ongoing research through software development improving or optimizing programs that already exist, and consulting for choosing the best technologies and techniques for their development.

SUMMARY OF THE RESEARCH LINE

Participation in national and international projects related to distributed grid & cloud computing and discussion and integration forums of these technologies from research to companies.

Technical configuration, integration, administration and user support of the Colossus and AraGrid infrastructures, both of them part of the CESAR supercomputing center. They have together more than 4000 computing cores and about 700TB of raw storage.

These infrastructures provide computing resources to a wide range of researches, who have specific or complementary requirements to those which HPC infrastructures offer. In addition to this, they also serve as a testbed for Spanish and European companies and SMEs, which are willing to adopt these technologies to improve their business model. Therefore, in the last years, we have focused our cloud research and infrastructures in helping SMEs on how to take advantage of these powerful technologies and it is one of our main objectives both offering IaaS (Infrastructure as a Service) computing resources and collaborating in the development and cloud integration of their applications.

Furthermore, the infrastructures are shared by the Ibergrid initiative (Spain & Portugal) and also by EGI (European Grid Infrastructure), which is one of the greatest distributed infrastructures of the world.

Teaching and dissemination: Due to the special requirements of Grid and Cloud infrastructures, we provide user support in the migration and adaptation of the applications in order to work within this distributed environments. Our team also actively collaborates in this kind of activities organizing workshops, courses, talks and meetings with companies, as well as the dissemination of all the projects in which we are participating.

SUMMARY OF THE RESEARCH LINE

Computers have become an essential tool in our quotidian lives. Very simple daily mundane activities as buying a train ticket or sending someone a message require the use of conventional computers. Of course, they also play a very important role in more difficult tasks, such as bank transfers or power grid management for instance. On the other hand, computers have also made possible many advances in Science and nowadays are patently present in a very wide set of different scientific areas. Indeed, many institutions around the World spend a huge amount of money and human effort to build clusters of computers (see for example, www.top500.org/lists/ for a detailed ranked list of the most powerful supercomputers in the World).

For some specific problems, however, conventional computers are not enough. They would spend thousands of years to perform some particular calculations. So in the framework of supercomputing one finds the Special Purpose Computers, which are developed and designed to perform some specific computing-intensive calculation.

The development of this kind of supercomputers is in fact the objective of this research line. So, thanks to a very successful scientific collaboration between researchers from BIFI and the Universidad de Zaragoza, Universidad Complutense de Madrid, Universidad de Extremadura, Università degli Studi di Roma “La Sapienza” and Università di Ferrara, the Janus supercomputer was born in 2008. It is a modular, massively parallel, and reconfigurable FPGA-based computing system for High Performance Scientific Computing. Its reconfigurable architecture would permit Janus to afford different scientific computational applications, as in Physic, in Chemistry or in Biology. So far, the Janus Collaboration focused its efforts on the study and simulation of spin glasses, paradigm of complex systems.

Janus is composed by 16 boards. On each board, a bidimensional 4×4 grid of FPGA-processors is located and linked obeying periodic boundary conditions. Each of these processors is called SP (Simulation Processor) and carries on the simulations. A 17th FPGA is settled in the middle acting as a crossbar and called IOP (Inpu/Output Processor), in charge of all internal connections and external communications. All FPGA modules are Xilinx Virtex4-LX200.

The Janus II Special Purpose Computer is the new generation supercomputer located at BIFI from 2013. Following the same successful Janus philosophy, JanusII is composed again by 16 boards. On each board, 16 latest generation FPGA processors (Xilinx Virtex-7 XC7VX485T FPGA) are located and linked obeying periodic boundary conditions. They are called SP’s from “Simulation Processor”, since they will be in charge of the simulations. All SP’s on each board are controlled by a full fledged computer that we call CP (Control Processor), running the Linux operating system. These CP’s configure all FPGA processors for the simulations, controlling and monitoring their status. The CP uses a commercially available Computer-on-Module system (COM), based on an Intel Core i7 processor; it connects via the PCIe interface to a so-called Input-Output-Processor (IOP) built inside yet another FPGA. The IOP actually manages all connections to all SP’s, controlling the configuration procedure and their operation, and monitoring their status. The Janus II architecture includes also improved communications, permitting the interconnection between all boards, and it enlarges 100 times the memory available.

JanusII was built thanks to FEDER funds: Ministerio de Economía y Competitividad (Gobierno de España), Gobierno de Aragón, European Union.
