Our Work

This research group has several lines of work. The most important are the following:


Numerical linear algebra in heterogeneous environments

The development of efficient algorithms and software to tackle NLA operations, from the perspective of high performance computing (HPC). Specifically, leveraging massively parallel platforms, such as graphics processing units (GPUs).

Cinque Terre

Large numerical model

The application of different HPC techniques to enhance the computational performance of large numerical models that simulate, for example, the state of the atmosphere or the behavior of waterbodies.


Optimizations in heterogeneous environments

The design of parallel metaheuristics that can profit from heterogeneous environments. This is specially relevant as problem instances are becoming increasingly large. Parallel metaheuristics usually exploit new enhanced search engines than traditional sequential algorithms.
