Computing and data science.

The BIFI is one of the most relevant e-science centers in Spain, both as resource providers and for scientific users. Composed mainly by engineers and physicists, the Computing & Data Science Area includes a wide range of activities such as technological research, user support, applied research, technology transfer and/or dissemination.

The BIFI houses the Aragón Supercomputing Center (Cesar), a computing infrastructure that encompasses a wide range of technologies: HPC (distributed and shared memory), grid, cloud, voluntary computing and dedicated computers.

The Computing & Data Science Area is structured in five research lines:

  • Citizen Science
  • Data Analysis, Advanced Visualization and Technology Transfer
  • High Performance Computing and Cloud Computing (HPC-Cloud)
  • Special Purpose Computers
  • Digital Science
  • Stochastic models and data analysis in Medicine and Climatology

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


Cloud infrastructures also provide computing resources for a wide range of researches, which have specific or complementary requirements to those offered by HPC infrastructures. In addition to this, they also serve as a test bed for Spanish and European companies and SMEs, which are willing to adopt these technologies to improve their business model. Therefore, in recent years, we have focused our research and cloud infrastructures to help 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.

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.

The main goal of this team is to research and support research whenever software development or data analytics are involved in the process. To achieve this, one of the most important tasks carried out is the participation in projects in which we collaborate with companies or other research groups. These collaborations are focused on topics such as BigData, Machine Learning, Internet analysis, social networks, distributed computing, new technologies in education, etc. The levels of collaboration range from small contributions to local companies or research groups to international projects.

The other task that we carry out in the BIFI is to support those researches that are being carried out; improving and optimizing programs that already exist, and conducting consulting work on the best technologies and techniques for development.

Computers have become an essential tool in our quotidian lives. Very simple daily mundane activities as train tickets booking or sending a message to someone 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, for a detailed ranked list of the most powerful supercomputers in the World).

However, for some specific problems, 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.

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 permits 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.


Janus retired in 2020 after 12 years of non-stop activity. It is currently found as an exhibition article in the hall of the Faculty of Sciences of the University of Zaragoza.

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.

The resources and computational infrastructure of digital media, including social networks, facilitate the creation and exchange of scientific knowledge not only among researchers in the STEM disciplines but also with the broader public. This line of research focuses on Science 2.0, and examines how science is communicated and disseminated on the Internet and social media, and how scientific knowledge is co-constructed through dialogic interactions within the scientific community and between the researchers and other interest groups (science stakeholders). Along these lines, we investigate why researchers need or want to communicate science in the context of Open Access (OA) and Open Science (OS) policies and how researchers perceive these policies and practices. We also investigate the repertoires of digital genres (written and spoken) that researchers currently use to bring science close to diversified audiences and, by this means, contribute to the democratization of knowledge and the promotion and development of scientific literacy and digital literacy in society.

We carry out quantitative and qualitative analyses to understand the construction of knowledge and knowledge dissemination online, to provide empirical descriptions of researchers’ digital literacy development and to identify the rhetorical strategies that scientists use to reach non-specialized audiences using one or more languages. We are also interested in identifying the STEM researchers’ language and communication needs to address them and enhance their communication skills, one of the key skills for the training of novice and experienced researchers according to the European Commission EURAXESS descriptors. At a methodological level, our research involves the use of digital humanities technologies for the analysis of textual data. Our emphasis is on the use of corpus linguistics, linguistic data processing, and small- and large-scale text mining techniques, as well as computational linguistics and ethnomethodological techniques. All these methods allow us to identify trends in multilingual science communication online and assess the use of language and linguistic repertoires to communicate and disseminate science online with and for society.

In addition, our research aligns with several of the Sustainable Development Goals (SDGs) of the United Nations 2030 Agenda, specifically those proposed by the World Federation of Science Journals. These are global warming and what societies can do to adapt to climate change, mental health, science and global health and the global biodiversity crisis. To do this, we use corpus of electronic texts to carry out descriptive characterizations of different genres for communicating science in digital media, with special attention to phraseological, discursive, pragmatic and rhetorical aspects, as well as features of lexical and syntactic complexity, register and discourse style. We also analyse assemblages of digital genres (for example, genre chains, genre systems, and genre ecologies) and the semiotic resources that researchers can use to disseminate science, including both single and multimodal genres and genres in one or more languages. The outcomes of this research is applied to teaching innovation, advising on scientific policies and language policies, as well as training human resources in the STEM fields in professional communication.

The research of Stochastic Models group (MODES) is structured around two lines of work:

– Analysis of extreme data with applications in Climatology. The main goal is the development of probabilistic and statistical tools to model extreme observations, especially those related with temperature and precipitation.  The analysis of this type of series requires spatio-temporal models, which are developed in a Bayesian framework. The applications focus on the analysis of series in the Ebro valley and Spain but the models can be extrapolated to other regions.

– Predictive models in Medicine. The group has developed statistical models in oncology and gynecology, including online calculators to predict the evolution of patients. We have also built models to be used as decision-aid tools for the management of hospitals. In particular, we have developed a multistate model for predicting hospital and ICU occupancy during a pandemic, such as COVID, which includes a freely available standalone tool. The group also works in the analysis of stochastic models for the logistics of the production process of blood components, in order to minimize expiry rates and maximize freshness.
