Euro-Par is an annual series of international conferences dedicated to the p- motion and advancement of all aspects of parallel and distributed computing. th Euro-Par 2009 was the 15 edition in this conference series. Througout the years, the Euro-Par conferences have always attracted high-quality submissions and have become one of the established conferences in the area of parallel and distributed processing. Built upon the success of the annual conferences and in order to accommodate the needs of special interest groups (among the conf- ence participants), starting from 2006, a series of workshopsin conjunction with the Euro-Par main conference have been organized. This was the ?fth year in which workshops were organized within the Euro-Par conference format. The workshops focus on advanced specialized topics in parallel and d- tributed computing. These topics re?ect new scienti?c and technological dev- opments. While the community for such new and speci?c developments is still small and the topics have yet to become mature, the Euro-Par conference o?ers a platform in the form of a workshop to exchange ideas and discuss cooperation opportunities. The workshops in the past four years have been very successful.

These proceedings aim to demonstrate the use of parallel and distributed processing concepts in di?erent application ?elds, and attempt to spark interest in novel research directions to advance the embracing model of high-performance computing research in general. The objective of these workshops is to speci?cally address researchers c- ing from university, industry and governmental research organizations and application-oriented companies, in order to close the gap between purely s- enti?c research and the applicability of the research ideas to real-life problems.

Euro-Par has for a long time been eager to attract colocated events sharing the same goal of promoting the development of parallel and distributed computing, both as an industrial technique and an academic discipline, extending the frontier of both the state of the art and the state of the practice. Since 2006, Euro-Par o?ers researchersthe chance to colocate advanced technical workshops back-to-back with the main conference. This is for a mutual bene?t: the workshops can take advantage of all technical and social facilities which are set up for the conference, so that the organizational tasks are kept to a minimal level; the conference can rely on workshopstoexperimentwithspeci?careasofresearchwhicharenotyetmature enough, or too speci?c, to lead to an o?cial, full-?edged topic at the conferenc
