Institution Background

University of Extremadura was founded in 1973 (law 991/1973, March 10th). Currently, the university offers more than 100 degrees in centers distributed across the region of Extremadura, at the west of Spain. University is divided up in four campuses sited in the main cities: the campuses of Badajoz, Cáceres, Plasencia and Mérida, the capital of the region. The university has around 24000 grade and undergraduate students and 8000 PhD students, and faculty comprises more than 1500 teachers.

 Research Group Background

The Media Engineering Group ( is a multidisciplinary group with a long experience in the area of signal processing, multimedia, database and advanced web topics. The HPC subgroup work is in the field of:

  • Message Passing Interface (MPI) standard and open-source implementations, including thread-based implementations for shared memory. Group develops and maintains its own implementation of the MPI called AzequiaMPI.
  • Programming models for high performance computing.
  • Theoretical and practical aspects of parallel performance modelling and optimizations.
  • Implementation of scientific applications, for instance, in the field of simulation of materials behaviour, mathematics numerical simulations, etc.

GIM group is composed of 14 associated professors and 6 PhD students. HPC subgroup is currently composed of 3 associated professors and a number of fellows.

HPC group works in contact with national institutions as CSIC (Advanced Research Council of Spain), CenitS (Extremadura Supercomputing Center) and Ceta-Ciemat (Extremadura Advanced Technologies Center).

The HPC group manages a little amount of own resources, with a small cluster, hardware accelerators, DSP processors, and counts with the technical support and supercomputing resources from the CenitS and Ceta-Ciemat.

The HPC group has participated in several national projects, such as “HESPERIA: Homeland Security: Integrated Infrastructures and Public Spaces Security Technologies” and “Multimedia Semantic Database Manager”, both founded by the CDTI (Industrial and Technology Development Center) that belong to the Spanish Government.


Major Interest in Action Scientific Topics

Current interest in the Nesus Cost Action is make relationships and work is close collaboration with research groups and people interested in the scope of the WG2:”Programming Models and Runtime Systems” for HPC platforms, and contribute with our developments and researches to the Action.
