Llorente graduated in physics with a major in computer science in 1992 and obtained his Doctor of Philosophy in physics with a speciality in computer science in 1995 at the Complutense University of Madrid and an Executive Master of Business Administration in 2003 from Individual Education Business School. After finishing his Doctor of Philosophy on efficient execution of scientific applications on parallel computers, he worked on parallel systems with different scaling models.
At National Aeronautics and Space Administration he conducted research on multigrid methods and their application to computational fluid dynamics, and their parallel implementation. Since 2002, Llorente led the Distributed Systems Architecture Research Group, in large-scale distributed infrastructures, advanced virtualization technologies and distributed computing, and resource provision platforms. Supporting projects including the European Union-funded RESERVOIR project
He has focused his research on architectures, meta-scheduling and benchmarking for grid computing.
And cloud computing architectures and federation. These efforts have resulted in several open-source technologies, such as Globus, GridWay, and OpenNebula.
Llorente was promoted to full professor in 2006. From 2002 to 2007, he also held a senior pesearcher position in the Advanced Computing Laboratory at Civil Aeronautics Board (Spanish National Research Council/ International Trademark Association center associated to National Aeronautics and Space Administration Astrobiology Institute).
In 2009 Llorente co-founded and co-chaired the Open Grid Forum Working Group on the Open Cloud Computing Interface.
Since 2009 he participated in the European Cloud Computing Group of Experts. In 2010, he co-founded C12G Labs, a cloud computing technology start-up which leads OpenNebula development.
