Title: Physarum Machines
Abstract:A Physarum machine is a programmable amorphous
biological computer experimentally implemented in a plasmodium of
Physarum polycephalum.
Physarum machines are programmed by configurations of repelling and attracting gradients, and localized reflectors. Physarum is a biological prototype of all storage modification machines and modern computer architectures.
In this talk it will be shown how a plasmodium of Physarum polycephlum can solve geometrical and graph-theoretic problems, implement logical computations and intelligence actuation.

Title: The Fresh Breeze Project
Abstract:
The development of multicore chips is producing a sea change in the world of computer system architecture. One result is the conventional program execution model (PXM), that has been the mainstay of commercial software development for more than thirty years, has been rendered obsolete. The Fresh Breeze PXM is proposed as a new basis for the design of massively parallel computer systems that can achieve high performance with sound support for program development including composability of parallel programs. The presentation will review the history of Program Execution Models (PXMs) and how their evolution has led to the Fresh Breeze project.

Title: The Future of High Performance Computing in Europe
Abstract:
This
talk will highlight the pan-European relevance high-performance
computing has gained. It will outline the setup of an HPC eco-system
and the challenges associated with this. Furthermore a strategic agenda
for high-performance computing will be presented including the
underlying fundamental data and the envisaged actions.

Title: Performance Modeling as the Key to Extreme Scale Performance
Abstract:
Parallel computing is primarily about achieving
greater performance than is possible without using parallelism.
Especially for the high-end, where systems cost tens to hundreds of
millions of dollars, making the best use of these valuable and scarce
systems is important. Yet few applications really understand how well
they are performing with respect to the achievable performance on the system.
The Blue Waters system, currently being installed at
the University of Illinois, will offer sustained performance in excess
of 1 PetaFLOPS for many applications. However, achieving this level of
performance requires careful attention to many details, as this system
has many features that must be used to get the best performance. To
address this problem, the Blue Waters project is exploring the use of
performance models that provide enough information to guide the
development and tuning of applications, ranging from improving the
performance of small loops to identifying the need for new algorithms.
Using Blue Waters as an example of an extreme scale system, this talk will describe some of the challenges faced by
applications at this scale, the role that performance modeling can play in preparing applications for extreme scale, and some ways in which performance modeling has guided performance enhancements for those applications.

Title: Europe's
Supercomputing Research Infrastructure PRACE
Abstract:
During
the last three years a consortium of 20 European countries prepared
the legal and technical prerequisites for the establishment of a
leadership-class supercomputing infrastructure in Europe. The
consortium named "Partnership for Advanced Computing in Europe"
has carried out a preparatory phase project supported by the European
Commission. The statutes of the research infrastructure association,
a Belgian "association sans but lucrative", were signed in
April 2010 and its inauguration took place in June 2010. Four members
have committed to provide compute cycles worth EURO 100 Million each
in the 5 years period until 2015. Six sites from the four hosting
countries in succession will install machines of the highest
performance class (Tier-0) for leading edge capability computing,
providing a diversity of architectures beyond Petaflop/s towards
Exaflop/s.
Access
to the infrastructure is provided on the basis of scientific quality
through a pan-European peer review scheme under the guidance of the
scientific steering committee (SSC) of PRACE. The SSC is an
autonomous group of leading European peers from a variety of fields
in computational science and engineering. Proposals can be submitted
in form of projects or as programs by communities. The provision of
computer time through PRACE started in August 2010 on the
supercomputer JUGENE of Research Centre Juelich.
Presently
PRACE is further developing its infrastructure in the first
implementation project soon to be followed by the second
implementation project, both again funded by the European Commission.
As important steps forward, PRACE's Tier-0 supercomputing
infrastructure will be complemented by national centres (Tier-1) of
the PRACE partners. In the tradition of DEISA, the Tier-1 centres
will provide limited access to national systems for European groups -
granted through national peer review - under the synchronization and
governance of PRACE. Furthermore, PRACE aims at establishing an
industrial user-vendor platform with the goal to create a European
Technology Platform for HPC.

Title: Challenges in Hybrid and Federated Cloud Computing
Abstract:
Federated and hybrid clouds will play a significant role in IT strategies and e-infrastructures in the coming years. The keynote describes the different hybrid cloud computing scenarios, ranging from the combination of local private infrastructure with commercial cloud providers that offer no real support for federation to one built on data centers of the same organization where the sites are completely dedicated to supporting all aspects of federation. The level of federation is defined based on the amount of information disclosed and how much control over the resources is provided across sites.
The talk presents the existing challenges for interoperability in federated and hybrid cloud computing scenarios, and ends with examples of multi-cloud environments running OpenNebula, such as the hybrid cloud computing approach in the StratusLab project.
