The third edition of the international Workshop on Virtual Prototyping of Parallel and Embedded Systems (ViPES’2015) took place in the beautiful island of Samos, Greece, on the 19th of July. In his role as program chair, Prof. Castrillon, together with Prof. Cristina Silvano from the Politecnico di Milano, put together a technical program with highly interesting presentations and keynotes. The workshop received submissions from 6 different countries (USA, Germany, China, Greece, Tunisia and Brazil) and was attended by above thirty participants. This edition of the workshop was co-located  with the 15th International Conference on Embedded Computer Systems: Architectures, Modeling, and Simulation (SAMOS). Therefore, ViPES profited from both the friendly atmosphere and the in-depth technical discussions that characterize the SAMOS conference, for which ViPES will stay in Samos for at least one more year.
