Welcome to the Parallel Computer Architecture Group Home Page. All the people in this group are working in the Computer Engineering Department (DITEC) of the University of Murcia.


The Parallel Computer Architecture Research Group (GACOP) of the University of Murcia began in 1995, being now fully consolidated and being one of the main pillars of the Faculty of Computer Science. Currently, the group is formed by thirteen members, seven of them with a doctorate degree (PhD). The philosophy of the group is to contribute high-quality scientific research and to be in permanent contact with national groups whose topics are similar to ours, as well as with some of the best-known European and American groups. As a result of this strategy, a significant percentage of the produced publications have emerged through collaborations with other groups. These works have been published in prestigious international journals (amongst IEEE-edited are TC and TPDS, and amongst Elsevier editions are JPDC, Parallel Computing, FGCS or JSA) and high-impact international conferences (HPCA, IPDPS, HiPC, ICPP, SC, ICS, EuroPAR, etc).

Early research by our group was centered around the topic of Supercomputing, and focused on interconnection networks, proposing several mechanisms to improve its performance in different conditions such as hot-spots, reconfigurable networks and fault tolerance under real-time constrains. In time, new research lines were launched with the goal to improve the services provided by clusters of PCs, in three ways: enhance processor performance and parallel system software, and develop efficient applications for high-performance environments.

Nowadays, our group is focused on topics related to multiprocessor on chip (CMP), such as to improve the performance of this architecture by developing new coherence protocols. Moreover, we are paying attention to reduce the energy consumption (at the level of the cores, memory and the interconnection network), to provide better fault tolerance to the architecture, and to the virtualization topic. Additionally, we are currently working on accelerating scientific applications for CMPs and GPUs architectures, specifically in the acceleration of bio-inspired algorithms for application in the field of Bioinformatics.

This page presents the members and the research topics of the group, including a short description of each topic and other group activities.
