This volume of LNCS contains the proceedings of the 6th European Performance
Engineering Workshop, held at Imperial College London during July 9–10, 2009.
This was the first in the EPEW series to be held in the UK, following on from the
highly successful workshops that were held in Toledo (2004), Versailles (2005),
Budapest (2006), Berlin (2007) and Palma de Mallorca (2008).
As with previous EPEW workshops, the event was supported by submissions
from all over the world, including Asia, the Middle East, North America, as well
as Europe. There were 33 submissions in total of which 13 were selected for full
papers and four as short papers. I would like to commend the diligent efforts
of the Programme Committee, who returned a complete set of reviews – four
per paper – which is most unusual. This enabled and enhanced the week-long
programme discussion which selected the papers presented here.
The papers themselves maintained the tradition of diversity and quality that
the European Performance Engineering Workshop has supported throughout.
Papers representing the different fields of performance engineering and analysis,
were broadly classified by applications, techniques and formalisms. In the
applications domain, we had a significant contribution, I believe for the first
time, in the modelling of auctions and markets. There were also contributions
on hardware modelling of RAID systems, as well as five papers on performance
aspects of cellular and fixed-line networks. New techniques presented included a
novel approach to mean value analysis, an application of stochastic ordering to
queueing networks and an interesting extension of passage-time analysis. Finally,
EPEW has always been supported by researchers using or enhancing stochastic
formalisms and this year we had: three papers based around the stochastic
process algebra, PEPA; a significant extension to tagged customers in generalized
stochastic Petri nets; and a paper looking at representation and analysis of
generally distributed stochastic systems.
As Programme Chair, I would like to thank everyone involved in making
EPEW 2009 a success: Springer for their continued support of the workshop
series, the invited speakers, the Programme Committee and reviewers, and of
course the authors of the papers submitted, without whom there could not be
a workshop. I would particularly like to thank Uli Harder and Maria Vigliotti
who worked extremely hard to bring together the LNCS volume and make all
the local arrangements a success. We hope that you, the reader, find the papers
in this volume interesting, useful and inspiring, and we hope to see you at future
European Performance Engineering Workshops. |
