Nova: CESGA’s TRAFAIR project was awarded Forum Pa at Rome

The Trafair Project has been awarded at the Pa Forum in Rome today with the "Sustainable PA Award, 100 projects to achieve the objectives of the 2030 Agenda".

The project TRAFAIR - Understanding Traffic Flows to Improve Air Quality (, co-funded by the European Community and in which CESGA participates, arose from the need of large cities to check air quality quickly and efficiently with a system that allows to take decisions that improve said quality benefiting citizens, businesses and administrations.

The objectives of this project are to provide estimates of air pollution in the city and to develop a prediction service based on the specific meteorology of the area and on the actual traffic flows that move through the city, in addition to publishing said data to the public.

These objectives are what have made TRAFAIR win the "Sustainable PA Award - 100 projects to achieve the objectives of the 2030 Agenda", initiative promoted by FPA in collaboration with ASVIS (Italian Alliance for Sustainable Development) in the event FORUM PA 2019 .

Nova: Big Data Workshop: Introduction to CESGA’s Hadoop 3 platform

This workshop will be a introduction to CESGA's Big Data platform. This platform was updated to Hadoop 3 and includes a new version of Spark 2.4.

This workshop will serve as an introduction to the tools available within the Hadoop 3 platform. The workshop will also serve as the basis for subsequent workshops on specific tools included in the platform, such as Spark.

Date: 11 june 10:00 a.m.  to 13:00 p.m.


Place: CESGA, Avda. de Vigo s/n, Campus Vida - Santiago de compostela

Recipients: The workshop is intended for both current users of the Big Data platform and new users who need access to Big Data tools.

What will I learn during the workshop?

At the end of the workshop you will know:

  • How to connect to the Hadoop 3 platform
  • How to transfer data efficiently
  • What tools that are available
  • How to launch these tools

What will NOT be taught during the workshop?

Given that this is an introductory workshop and the wide variety of tools available, this workshop will not explain how to use each of the tools, but it will simply show how to access them, their main features and how they are launched.

Subsequently, specific workshops will be held that will focus on specific tools such as Spark, where its use will be taught in detail.

Nova: Big Data Platform upgraded to Hadoop 3

The Big Data platform has been upgraded to Hadoop 3, including also the new Spark 2.4.

The Big Data service allows not only processing in parallel large volumes of information, but also collecting and processing streaming data and using Jupyter Notebooks for exploration and visualization tasks.

The service is based in the last version of Cloudera's Hadoop distribution, CDH6, based on Hadoop 3 which offers a stable solution that included numerous components of the Hadoop ecosystem: YARN, HDFS, MapReduce, Spark, Flume, Hive, Impala, HBase, ...

The upgraded platform is accessible using SSH to ****, while the old one based on Hadoop 2 will continue to be accessible through To ease the transition, the old platform will remain active until June 30, when it will be shutdown.

In the new User Guide that has been prepared there is a section explaining how to migrate the data from HDFS:

It is not neccessary to migrate the data in the HOME filesystem since the data in the old platform have been automatically migrated from GlusterFS to the new HOME.

For more information about the platform, including tutorials to quickly learn the different tools, we recommend you to access the following portal that isdevoted to the platform:

This portal included a web interface (WebUI) that allows to perform most common tasks using the browser. We also recommend you to read the new user guide that we have prepared:

Nova: Advanced Course - IHFOAM applied to Coastal engineering - FOAM@Iberia 2019 - Jun 11th and 12th - Porto

The 3rd FOAM@Iberia Meeting, to be held in 11-12 June at the Faculty of Engineering of the University of Porto (Portugal), will be the annual meeting point of the OpenFOAM® Iberian community.

We are pleased to announce the Advanced Course on IHFOAM applied to Coastal engineering by Dr. Gabriel Barajas at the 3rd Iberian meeting of OpenFOAM® technology users, FOAM@Iberia 2019.

Dr. Gabriel Barajas, from the Coastal Hydrodynamics and Infrastructures Group at IHCantabria , has a degree in Physical Science and Master in Integrated Coastal Zone Management by the Universidad de Cantabria. Gabriel works in the coastal engineering field, developing numerical tools in 2D and 3D, validation and application to research and consultancy projects, both nationally and internationally. He is one of the developers of IHFOAM .

IHCantabria , the Environmental Hydraulics Institute from the Cantabria University, is a research institute with over 140 researchers and 30 years of experience in the fields of hydraulics, hydrodynamics, offshore engineering and fluid structure interaction among others.

IHFOAM is a three-dimensional numerical two-phase flow solver designed to simulate coastal, offshore and hydraulic engineering processes. It presents a wide collection of boundary conditions which handle wave generation and active absorption at the boundaries, that allow the generations of any type of wave in a 3D domain, from the most simple regular waves to complex, real and fully 3D irregular directional sea states.
