The Networks and Virtual Environments Group (GREV) focus its current research in interconnection networks of distributed systems and high-performance computations (HPC).

The GREV was founded in 2003 and throughout the years has worked in different lines of research, linked to projects of the National Plan:

- Distributed Virtual Environments:It tries to improve the perks of virtual environments that allow the simulation in virtual worlds, 3D virtual reality and videogames. This line was developed between 2003 and 2009

- Collaborative augmented reality (CAR): This line is focused in improving the perks of CAR systems based on mobile phone, as a high-level distributed application, for allowing the use of virtual reality in mobile devices. This line was developed between 2010 and 2014

-Crowd simulation: It pursues the design, implementation and visualization of multi-agent systems in a large scale on high-performance computers, in order to simulate the response of different populations to different catastrophic events such as fires, earthquakes, etc... This line was developed between 2007 and 2014.

- Multiscale systems based on social simulation techniques : Development of multi-agent simulation systems that simulate human behaviour in mobility policies, as well as the effect of this behaviour in urban areas. This line was developed between 2011 and 2016

- Computational genomics:It intends to optimise the existent software and develop new software for using all the existent resources in current computers (multi-core processors, graphics processors, etc). that allow a substantial progress in genomic knowledge, specially in the filed of DNA methylation analysis. This line has been being developed since 2015 from these days.

The GREV conducts its research as a member and in cooperation with the ACCA team, formed by research groups of 4 Spanish universities, and whose has participated in coordination since its foundation.
