Welcome!

The Parallel Computing and Mobile Systems Laboratory (COMPASSO), established in the 1980s, is one of the research laboratories of the Systems and Computer Engineering Program (PESC) at COPPE/UFRJ. The laboratory team consists of professors, researchers, MSc and DSc students from the Architecture and Operating Systems (ASO) area, and undergraduate students from UFRJ.

COMPASSO's research projects develop high-performance computing platforms for various classes of parallel and distributed applications in the areas of scientific computing, cloud computing, e-commerce, and multimedia, using clusters of server computers, GPUs, and multiprocessors, in combination with efficient software and/or hardware techniques and mechanisms.

The COMPASSO team also develops mobile communication systems to broaden the spectrum of applications, from Information Security and Environmental Monitoring to Disaster Risk Management, Vehicular Networks, and Precision Agriculture, and to meet the growing demand for Information Technology in Smart Cities, Industry 4.0, and the Internet of Things. 

The COMPASSO laboratory maintains collaborations with other laboratories at COPPE/UFRJ and partnerships with other public and private institutions. Financial support for our research activities comes primarily from national agencies (FINEP, CNPq, FAPERJ, and CAPES) and partner companies.
