Executive Summary PRACE, the Partnership for Advanced Computing in Europe, and DEISA, the Distributed European Infrastructure for Supercomputing Applications, merged for the first time their annual science symposia into one big European HPC (High Performance Computing) event: The DEISA PRACE Symposium 2009. This symposium took place from May 11 to 13 in Amsterdam, and was hosted by SARA and NCF at the Royal Tropical Institute. The theme of the symposium was "HPC Infrastructures for Petascale Applications", it was of major interest to a broad audience: from scientific users, HPC technology experts and vendors to government representatives and industry partners. The symposium attracted almost 200 participants from more than 20 countries and four continents. Prominent keynote speakers from all over the world gave their global perspectives of High Performance Computing in the Petascale era, the new generation of supercomputers for scientific research. The symposium also featured speakers from different science communities. PRACE provided its perspectives on HPC architectures, Applications, Training and Education. DECI, the DEISA Extreme Computing Initiative presented ten computational science grand challenge projects from all over Europe covering many science areas. The DEISA PRACE symposium was very successful regarding to the number of participants, the relations to the European scientific communities established, and the overall feedback received from the participants. The symposium was a follow-up event to the first PRACE Scientific Conference held on 26 November 2008 in Lyon, organised alongside ICT 2008. PRACE - RI-211528 1
1 Introduction The mission of PRACE is the preparation of a persistent pan-european high performance computing (HPC) service to meet the needs of academia, industry and society. Supercomputers enable scientists and engineers to solve today s problems and to develop the new technology for tomorrow s industry, affecting national employment patterns and national wealth. To further the aim of enabling the academic and industrial research in Europe to develop and use world class HPC, it is important to strengthen contacts with and between scientific communities; in particular those who are involved in helping to develop the very science case on which this effort is based. To this end, PRACE was responsible for organising two scientific conferences during the course of the project. The first of these was held on November 26, 2008 in Lyon, organised alongside ICT 2008, the largest research event for information and communication technologies in Europe. The second one, the DEISA PRACE Symposium, was held on May 11 13, 2009 in Amsterdam, the Netherlands. This event is the focus of the present report. 2 Motivation and Venue The first PRACE scientific conference was held on November 26, 2008 in Lyon, organised alongside ICT 2008, the largest research event for information and communication technologies in Europe. The previous DEISA Symposia have been arranged in Paris (2005), Bologna (2006), Munich (2007) and Edinburgh (2008). This year, DEISA and PRACE for the first time merged their annual science symposia into one big European HPC event: The DEISA PRACE Symposium 2009. The symposium took place at the Royal Tropical Institute (KIT) in the heart of Amsterdam and it was jointly hosted by SARA and NCF. The location of the venue had been predetermined by DEISA before the two projects aggreed on a joint event. The aim of the symposium was to reach the scientific users, HPC technology experts and vendors, government representatives and industry partners that are likely to contribute or benefit from the future HPC infrastructure deployed by PRACE and DEISA. The theme of the symposium was HPC Infrastructures for Petascale Applications. This is what PRACE and DEISA are jointly creating for Europe and what other organisations and projects are building in the USA and Asia. Prominent keynote speakers from all over the world gave global perspectives of High Performance Computing (HPC) in the Petascale era providing an overview of the new generation of supercomputers for scientific research. Speakers on the first day included Kostas Glinos of the European Commission, Abani Patra from the National Science Foundation (USA), Ryutaro Himeno from RIKEN (Japan), Horst Simon from the Department of Energy (USA), Ben Evans from the Australian National University (Australia) and Vladimir Voevodin from the Moscow State University (Russia). The symposium also featured speakers from different science communities: cosmology, fusion research, climatology and biosciences. PRACE additionally provided its perspectives on HPC architectures, Applications, Training and Education. PRACE - RI-211528 2

3 Organising Committees The organisation of this symposium was divided into two groups: the programme and the organising committee. Some of the members of the programme committee had an initial meeting about the symposium during SC08 in December 2008 in Austin, Texas. The first teleconference took place on 9 January, 2009. This teleconference was a start-up teleconference in which everyone of the DEISA PRACE organisation participated. Afterwards the communication between all organisers took place via e-mail and therefore two e-mail aliases were created: deisa-prace-symposium@fz-juelich.de reaching all organisers deisa-prace-symposium-contact@fz-juelich.de reaching only the organising committee. In addition, the organising committee had weekly teleconferences: in total 18 teleconferences were arranged regarding the DEISA PRACE symposium. 3.1 Programme Committee The programme committee was in charge of the symposium programme, the overall coordination of the symposium including political and financial issues. The programme committee consisted of the following people: Axel Berg, SARA, host site representative Thomas Eickermann, FZJ, PRACE project manager Hermann Lederer, RZG, DEISA dissemination leader Achim Streit, FZJ Andreas Schott, RZG Ari Turunen, CSC, PRACE dissemination leader The Programme committee invited the speakers on behalf of PRACE project coordinator, Prof. Dr. Achim Bachem and DEISA project coordinator, Dr. Stefan Heinzel. 3.2 Organising Committee The organising committee consisted of a local organisers group with people from the Netherlands: Marina den Hartog, SARA Naomi Messing, NCF Dionne Verhoeven, SARA In addition to the local organisers, CSC was involved in the organising committee: Anni Jakobsson (PRACE dissemination officer) and Heli Autere (DEISA representative) CSC took part of the dissemination, website and graphical design of the symposium s material. The DEISA website was updated by Markus Rampp and Johannes Reez from RZG. PRACE - RI-211528 4
4 Dissemination One of the aims of the symposium was to provide an opportunity for PRACE to strengthen its links with HPC initiatives in the US, Japan, and other parts of the world in order to get their experience and practice of managing, running and scaling applications to Petaflop/s levels. This valuable information is to be used in assisting the decision making process in PRACE. The links and relationships created in the symposium are described in this document chapter 5.1. The symposium was meant for a broader audience: from scientific users, HPC technology experts and vendors to government representatives and industry partners. This had to be taken into account when inviting possible participants. The economical recession in the world also affected the symposium as many companies and institutes had travel restrictions at the time. Despite of this, the organisers were very successful getting people to this seminar. Other European projects, such as HPC-Europa2 and Belief-II, were taken into account in dissemination as well: the symposium was advertised at the Belief-II site, and HPC-Europa2 dissemination material was available at the symposium exhibition (see more from chapter 4.8. of this document). 4.1 Invitations The programme committee took care of inviting the speakers to the seminar on behalf of PRACE project coordinator, Prof. Dr. Achim Bachem and DEISA project coordinator, Dr. Stefan Heinzel. The programme consisted of a total of 30 speakers. The details of the programme are reported in section 4.5. The potential participants were invited by the organising committee. The DEISA and PRACE stakeholders were invited with the help of the DEISA and PRACE partners by sending invitations by e-mail and advertising the event at DEISA and PRACE partners websites. There was no attendance fee for the event for the participants. A total of 182 participants took part to the event. More detailed summary of the participants in this report is stated in section 5. 4.2 Press Releases A press release HPC Infrastructures for Petascale Applications DEISA PRACE Symposium 2009 was published before the event on 25 February 2009 on both PRACE and DEISA websites. In parallel it was also sent to various online HPC magazines, such as HPCWire, International Science Grid This Week, Inside HPC, Scientific Computing World and to the Primeur magazine. The press release was also distributed via the AlphaGalileo [2] service the world's leading source of European research news which reaches over 6,000 journalists worldwide. URL to the press release on the PRACE website: http://www.prace-project.eu/news/hpc-infrastructures-for-petascale-applications-2013-deisaprace-symposium-2009 Another press release was published after the event, covering the outcome of the symposium. This press release was published on 22 May, 2009 using the same distribution channels as the first press release. URL to the second press release on the PRACE website: PRACE - RI-211528 5
http://www.prace-project.eu/news/the-deisa-prace-symposium-attracted-almost-200- participants-from-more-than-20-countries-and-four-continents The press releases gained press cuttings all across Europe, for example in HPCWire. The Primeur magazine made feature articles about the event. One of them was entitled Amsterdam was supercomputing capital of Europe for three days [3]. 4.3 Websites Figure 2: DEISA PRACE Symposium 2009 web (After the event the site was moved to the section of past events on the PRACE website: The PRACE [1] and DEISA [4] websites featured specific sections for the event.

The following notes from the DEISA PRACE Symposium are made by Wolfgang Gentzsch and published in the DEISA newsletter 3/2009. Figure 7: Kostas Glinos, Head of Unit, Géant and e-infrastructures of the European Commission Kostas Glinos, Head of Unit, Géant and e-infrastructures of the European Commission, was highlighting the ambition to make Europe a leading player in supercomputing, not only from the user perspective, but also for European suppliers of components, software, systems, and services. Glinos stated that this can be achieved when Member States and the Commission join forces and pool investments. He also noted that it is up to the scientific community to implement a coordinated plan of action. The supercomputing strategy should strengthen the European researchers in their global competitiveness. Areas such as medicine, climate and energy are of worldwide importance. The European Commission is stimulating the support for escience with e-infrastructures consisting of high-speed networking, Grid infrastructures, and data infrastructures. A relative new item is supercomputing. The goal is to increase the number of Europe-based supercomputers in the upper regions of the TOP500 list. Also the European IT industry should be encouraged. PRACE - RI-211528 12
Figure 8: Maria Ramalho Natário from the European Commission Maria Ramalho Natário from the European Commission explained, that the focus is more on a complete European HPC ecosystem, with different machines and Grids at different levels, but accessible by a scientist through a workspace that hides as much as possible the complexity of the systems and the Grids, such that a researcher can create workflows where different steps can use different system architectures or Grids when needed. The next funding call for projects, that opens in July 2009 and closes in November 2009 will support this complete ecosystem. Figure 9: Abani Patra from the NSF, USA PRACE - RI-211528 13
Abani Patra from the National Science Foundation (USA) in his Global perspective presentation talked about Computational Discovery at Scale. One of his key messages was about the new oracle Predictive Science. This means that data, models and people together build a systematic integration of observational data, knowledge of physics and best available computing methodology and hardware to extrapolate from available data and settings. He closed his presentation with a set of challenging questions which are worth noting: What are the new applications that are emerging or likely to emerge in the coming decade? How can we best stimulate development of software for applications and the hardware architectures to match? How can useful software that has been developed be sustained beyond the development period? What systems software will be required? Distributed systems support, programming environments, runtime support, data management user tools? What application support environments will be needed? Application packages, numeric and non-numeric library packages, problem solving environments? How can we aid or catalyze developments that make it possible to use the same tools, including compilers, debuggers and performance tools, on system scales all the way down to the typical researcher s laptop or desktop? What education and training actions should be considered to prepare researchers, students and educators for future cyber infrastructure? Figure 10: Horst Simon from Lawrence Berkeley National Laboratory, USA PRACE - RI-211528 14
Horst Simon from Lawrence Berkeley National Laboratory (USA), gave an overview of the current supercomputing developments in the USA. With two supercomputers currently running at over a petaflop/s, and studies underway on exascale systems, many people believe we will reach exascale computing in a decade. Horst Simon said this is too optimistic. Exascale computer architectures necessitate radical changes to the software used to operate them and the science applications. The change is as disruptive as the shift from vector to distributed memory supercomputers 15 years ago. The current message passing coupled with sequential programming languages will be inadequate for architectures based on many-core chips. The present code development, correctness, and performance analysis tools cannot scale up to millions of threads that will run in an exaflop/s computer. With perhaps millions of cores, exaflop/s computers are bound to fail on at least small parts, very often. But the current check pointing will be inadequate for reaching fault tolerance at the exascale. The exaflop/s systems will also produce massive amounts of data. Fundamental changes are necessary to manage and extract knowledge from this tsunami of data. We certainly cannot devote all of our HPC efforts to exascale systems. Though the first supercomputers have crossed the petaflop/s barrier, we still are not at a level where day-today sustained petaflop/s performance is delivered to many types of applications. Horst Simon sees no coherent Petascale software plan across different platforms and different agencies (in the US). The USA is spending a lot of money each year on HPC. For the fiscal year 2009, Horst Simon estimates that it amounts to probably about $2B total: High End Computing Infrastructure and Applications get $1,142 M and High End Computing R&D $492 M. Figure 11: Vladimir Voevodin from the Moscow State University Vladimir Voevodin from the Moscow State University (MSU) presented Russia s way to petaflop/s. Currently the fastest system in Russia is on position 35 in the TOP500 with 70 teraflop/s performance. Vladimir Voevodin, expects that by next year a machine with 0.5 PRACE - RI-211528 15
petaflop/s performance will be operational. The new 258,48 teraflop/s MSU supercomputer will be installed in Q3 09, and upgraded early next year to 500 teraflop/s. Other Global perspectives were presented by Ryutaro Himeno from RIKEN (Japan), Ben Evans from the Australian National University (Australia), and John Towns from TeraGrid (USA). Achim Bachem from Research Centre Juelich (FZJ) and Coordinator of PRACE, and Stefan Heinzel from Garching Computing Centre (RZG) of the Max Planck Society and Coordinator of DEISA, both stressed the importance of a joint European approach to high-performance computing, which is done in a complementary way, with PRACE focusing on new European leadership-class top-tier systems, and with DEISA operating and further improving the existing distributed supercomputing infrastructure. Achim Bachem presented a detailed map on how Europe is moving ahead towards a persistent high-end computing service for the global scientific community, as a part of the long-term roadmap detailed in the ESFRI European Strategy Forum on Research Infrastructures. Within PRACE, the partners are installing several petaflop/s systems over the next five years. Concerning HPC, a total of 20 European PRACE member states are now talking with one voice. All PRACE member states will need the skills for peta- and exascale computing. Stefan Heinzel stated that the European HPC infrastructure has been built and operated successfully over the last few years. He also noted that the European HPC infrastructure has been used intensively by the computational science community. Now the focus needs to be more on the grand-challenge applications for petascale computing, running potentially on hundreds of thousands of processor cores. Challenges of dramatic optimisation, multithreading, new parallelisation strategies, new programming methods, new algorithms, libraries and tools are faced, and new codes will have to be developed through strong science community efforts in cooperation with the supercomputing centres. The symposium also featured speakers from various science communities. "High-performance computing is crucial for climate research to understand mechanisms of climate change and predict future climate change perturbed by human activities. The powerful computing is needed to understand and to predict extreme events and assess the regional impacts of the climate change on society and economy", stated Prof. Sylvie Joussaume, researcher at CNRS and expert in climate modelling. She is also chairing the European Network for Earth System modelling (ENES). ENES has started the new FP7 Infrastructure project IS-ENES to better understand and predict future climate change by high-end simulations. In the Life Science community talk Prof. Peter Coveney from University College London presented the Virtual Physiological Human project with collaborations from seven European countries. Prof. Frank Jenko from the European Fusion Research community, researcher at the Max Planck Institute for Plasma Physics, presented an overview of the world-wide ITER project and the HPC needs for its success. Prof. Carlos Frenk from Durham University gave a brilliant insight into the world of cosmology and the challenging simulations of cosmic evolution by the VIRGO Consortium, the world-leading group in this field. All four science communities are supported by DEISA and plan to use the PRACE petaflop systems. PRACE - RI-211528 16
PRACE also provided its perspectives on HPC architectures, Applications, Training and Education. PRACE was presented by Aad van der Steen (The Netherlands) with a presentation Directions in HPC Technology, Mark Bull from EPCC (UK) with a presentation Survey of HPC Systems and Applications in Europe, and Tim Stitt from CSCS (Switzerland) with a presentation Training and Education for Petascale Computing. From the DEISA Extreme Computing Initiative ten computational science grand-challenge projects from all over Europe were presented: Harm Jonker (Weather and Climate Research, The Netherlands & UK), Hans-Joachim Bungartz (Engineering, Germany), Hannu Häkkinen (Materials Science, Finland), Rosa Dominguez-Tenreiro (Astrophysics, Spain), Jean-Philippe Laval (Engineering, France), Michele Migliori (Computational Neuro Sciences, Italy), Matthias Krack (Materials Science, Switzerland), Luís O. Silva (Plasma Physics, Portugal), Rainer Spurzem (Astrophysics, Germany), and David van der Spoel (Computational Bio Sciences, Sweden). Last but not least, Zoltan Fodor from the University of Wuppertal reported on the QCD Breakthrough 2008: The Origin of Mass of the Visible Universe, trying to answer the question of what is the source of the mass of the ordinary matter, successfully, in layman s terms. 4.6 Speakers Biographies and Abstracts Speakers biographies and abstracts of the presentations were distributed to every participant in the conference kit. The biographies and abstracts can be found in Annex 9.3. 4.7 Other material A banner for the entrance of the Royal Tropical Institute was created (Figure 12) for the DEISA PRACE Symposium. Also, a foam board for the lectern and two roll-ups (Figure 6) one DEISA and one PRACE, were created. All attendees got a name badge (Figure 13).

4.9 Conference Evening Figure 15: Posters at the DEISA PRACE Symposium A conference evening was arranged on Tuesday, May 12. The purpose of the evening for the participants was to get to know each other better in a less formal atmosphere and to build collaborations within the HPC community. The conference evening started at 19:00 hrs with a boat trip through the canals of Amsterdam. Later, the boats arrived at Restaurant d Vijff Vlieghen where the participants disembarked for the conference dinner. The evening ended around 23:00 hrs.

5 Attendees DEISA PRACE Symposium 2009 attracted 182 participants from 22 countries. Table 1: DEISA PRACE Symposium participants A complete list of attendees with their names, countries and affiliations can be found on Annex 9.1 of this document. 5.1 Relations to Stakeholders One aim of the symposium was to create stronger links with initiatives in the US, Japan, and other parts of the world in order to gain experience and practice of managing, running and scaling applications to Petaflop/s levels. This information is to be used to assist the decision making process in PRACE. The symposium was aimed to a broad audience: from scientific users, HPC technology experts and vendors to government representatives and industry partners. The symposium managed to attract a wide audience covering many science fields, science communities and projects, such as CNRS, ENES and IS-ENES, ITER-project and VIRGO Consortium. The symposium offered PRACE the possiblity to establish stronger links with the aforementioned communities and projects, covering geographically various countries and continents. PRACE - RI-211528 20
6 Post-event Activities The press release, which was published after the symposium, gained press cuttings all across Europe, for example in HPCWire. The Primeur Magazine made feature articles about the event. One of them was entitled Amsterdam was supercomputing capital of Europe for three days [3]. Feature articles about the event were published in PRACE and DEISA newsletters. After the symposium the organising committee sent follow-up e-mails to all speakers and attendees. The e-mail included links to the presentations, the evaluation form and the list of participants. Pictures taken from the event are available on PRACE and DEISA websites. A wider picture archive is available on the Picasa picture service [5]. It is possible to get access to the picture archive by sending a request to the organisers: deisa-prace-symposium-contact@fz-juelich.de. 7 Feedback An evaluation form (Annex 9.2.) was given to every symposium participant in the conference kit which was delivered at the symposium. Attendees were reminded to fill the evaluation form and return it to the registration desk. The form was also sent to all symposium attenedees after the event via e-mail. A total of 35 forms were given back to the symposium organisers. 62% of the respondents thought that the symposium was very productive and 35% thought that the symposium was productive. 45% of the respondents gave 1 (excellent) to the relevance, agenda and discussions at the symposium; 37% of the respondents gave 2 on a scale of 1 (excellent) to 5 (poor). The organisation of the symposium at the same 1 to 5 scale got the following percentages: 1 (excellent) 72% and 2 from 22% of the respondents. Below are more comments and more detailed answers from the respondents.

The three-day programme consisting of 30 speakers from around the world was an achievement of itself. The feedback from the symposium was overall very positive. 97 per cent of the respondents regarded the symposium very productive (62%) or productive (35%). A total of 45 per cent of the respondents gave 1 (excellent) to the relevance, agenda and discussions at the symposium; 37 per cent of the respondents gave 2 on a scale of 1 (excellent) to 5 (poor). The organisation of the symposium at the same 1 to 5 scale got the following percentages: 1 (excellent) 72 % and 2 22% of respondents. This information was gathered from an evaluation form which was given to every symposium participant. A total of 35 forms were given back to the symposium organisers. The organising committee recommends that in the future at similar kind of events the evaluation form should also be available online. This way people might leave more feedback. The Primeur Magazine stated Amsterdam was supercomputing capital of Europe for three days.
