Dear Steering Committee of the Euro-Par,
Dear Euro-Par Team 2019,
Dear Conference Participants.
On behalf of the Partnership for Advanced Comput-
ing in Europe, I would hereby like to congratulate the
Euro-Par conference – and the team behind it – on
the 25th anniversary of the event. Covering all aspects
of parallel and distributed processing, the Euro-Par
conference has continuously helped to develop the
use of High Performance Computing in Europe and
beyond. Providing a forum for interaction within the
HPC eco-system for so many years consecutively is
both a goal and an achievement in one.
I wish you a memorable conference in Göttingen.

15SPOTLIGHT ON THE EURO-PAR
Since 1995 Euro-Par, an annual series of interna-
tional conferences has been established as one of
the most important High Performance Computing
Conferences dedicated to the promotion and ad-
vancement of all aspects of parallel and distributed
computing.
Euro-Par’s objective is to be the primary choice of
such professionals for the presentation of new re-
sults in their specific areas. As a wide-spectrum
conference, Euro-Par fosters the synergy of different
topics in parallel and distributed computing.
Euro-Par covers a wide spectrum of topics from Euro-Par provides a forum for the introduction, pre-
algorithms and theory to software technology and sentation and discussion of the latest scientific and

University of Santiago de Compostela, Spain
In 1996, the Euro-Par conference was designed as a
set of co-located workshops. The driving vision was
that each of the workshops was entrusted to a small
committee, made of representative members of a
specific scientific community. This committee was
in charge of defining the workshop scope, writing
the call for papers, selecting the submissions, orga-
nizing the program, chairing the sessions and doing
their best to foster interactions between attendants.
The Euro-Par organization was in charge of the glob-
al infrastructure: listing the invited scientific commu-
nities, identifying a workshop chair for each of them,
and building up the overall technical, financial and
commercial structure to host all the workshops.
In 1996, 22 workshops were launched. A number of 2006. The model became stable, and the list of top-
