Preface
This volume contains the papers presented at the 26th International European Con-
ference on Parallel and Distributed Computing (Euro-Par 2020), planned for August
24–28, 2020, in Warsaw, Poland. Due to the coronavirus pandemic, Euro-Par was
organized this year as a virtual conference.
Forover25years,Euro-Parhasconsistentlybroughttogetherresearchersinparallel
and distributed computing. Founded by pioneers as a merger of the three thematically
related European conference series PARLE and CONPAR-VAPP, Euro-Par started
withtheaimtocreatethemainannualscientificeventonparallelprocessinginEurope
and to be the primary choice of professionals for the presentation of the latest results.
Sinceitsinception,Euro-Parhasbeencoveringallaspectsofparallelanddistributed
computing,rangingfromtheorytopractice,fromthesmallesttothelargestparalleland
distributed systems and infrastructures, from fundamental computational problems to
full-fledged applications, from architecture, compiler, language, and interface design
and implementation to tools, support infrastructures, and application performance.
Euro-Par’s unique organization into topics provides an excellent forum for focused
technical discussion as well as interaction with a large, broad, and diverse audience
who are researchers in academic institutions, public and private laboratories, or com-
mercial stakeholders. Euro-Par’s topics were always oriented towards novel research
issues and the current state of the art. Most topics became constant entries, while new
themes emerged and were included in the conference. Euro-Par has a tradition of
selecting new organizers and chairs for every edition, leading to fresh ideas and
variationswhilestayingtruetothetradition.Organizersandchairsofpreviouseditions
support their successors. In this sense, Euro-Par also promotes networking across
national borders, leading to the unique spirit of Euro-Par.
Previous conferences took place in Stockholm, Lyon, Passau, Southampton, Tou-
louse,Munich,Manchester,Paderborn,Klagenfurt,Pisa,Lisbon,Dresden,Rennes,Las
Palmas, Delft, Ischia, Bordeaux, Rhodes, Aachen, Porto, Vienna, Grenoble, Santiago
de Compostela, Turin, and Göttingen.
Thus, Euro-Par in Poland followed the well-established format of its predecessors.
The 26th edition of Euro-Par was organized with the support of the University of
Warsaw, Faculty of Mathematics, Informatics and Mechanics (MIM UW) and AGH
University of Science and Technology, Faculty of Computer Science, Electronics and
Telecommunications, Department of Computer Science in Krakow. MIM UW is a
renowned place for research in mathematics and theoretical computer science, while
AGH hosts the largest supercomputer in Poland in its Academic Computer Centre
Cyfronet.
The topics of Euro-Par 2020 were organized into 11 tracks, namely:
– Support Tools and Environments
– Performance and Power Modeling, Prediction and Evaluation
– Scheduling and Load Balancing
vi Preface
– High Performance Architectures and Compilers
– Data Management, Analytics and Machine Learning
– Cluster, Cloud and Edge Computing
– Theory and Algorithms for Parallel and Distributed Processing
– Parallel and Distributed Programming, Interfaces, and Languages
– Multicore and Manycore Parallelism
– Parallel Numerical Methods and Applications
– Accelerator Computing
Overall, 158 papers were submitted from 33 countries. The number of submitted
papers,thewidetopiccoverage,andtheaimofobtaininghigh-qualityreviewsresulted
in a difficult selection process involving a large number of experts. As the joint effort
ofthemembersoftheProgramCommitteeandofthe169externalreviewers,atotalof
256reviewersfrom29countrieswrote632reviews:17papersreceivedthreereviews,
129receivedfourreviews,and14received5ormore,thatis,onaverage,4reviewsper
paper. There were more than 218,000 words in all the reviews. The accepted papers
were chosen after offline discussions in our reviewing system followed by a lively
discussionduringthepaperselectionmeetingwhichtookplaceviaavideoconference
on April 21, 2020. As a result, 39 papers were selected to be presented at the con-
ference and published in these proceedings, resulting in a 24.6% acceptance rate.
The Technical Program Committee distinguished one best paper: “Maximizing I/O
Bandwidth for Reverse Time Migration on Heterogeneous Large-Scale Systems” by
Tariq Alturkestani, Hatem Ltaief, and David Keyes.
To increase reproducibility of the research, Euro-Par encourages authors to submit
artifacts, such as source code, datasets, and reproducibility instructions. Along with
notification of acceptance, authors of accepted papers were encouraged to submit
artifacts.Artifactsfor13papersweresubmitted(athirdoftheacceptedpapers).These
artifacts were then evaluated by the Artifact Evaluation Committee (AEC). The com-
mitteemanagedtosuccessfullyreproduceresultsofallthe13papers.Thesepapersare
marked in the proceedings by a special stamp, and the artifacts are available online in
the Figshare repository.
Inadditionto thetechnicalprogram,we had thepleasure ofhosting three keynotes
held by:
– Ewa Deelman, University of Southern California, USA
– Geoffrey Fox, Indiana University, USA
– Piotr Sankowski, University of Warsaw, Poland
Euro-Par 2020, though a virtual event this year, encouraged interaction and online
discussions, in order to make it a successful and friendly meeting.
The conference program started with two days of workshops on specialized topics.
Dora Blanco Heras and Bartosz Baliś ensured coordination and organization of this
pre-conference event as workshop co-chairs. After the conference, a selection of the
paperspresentedattheworkshopswillbepublishedinaseparateproceedingsvolume.
We would like to thank the authors, chairs, Program Committee members, and
reviewersforcontributingtothesuccessofEuro-Par2020.Similarly,wewouldliketo
extend our appreciation to the Euro-Par Steering Committee for its support. Our
