In EU FP7, the DEISA Consortium continues to support and further develop the distributed high performance computing infrastructure and its services through the DEISA2 project funded for three years as of May 2008.
Activities and services relevant for Applications Enabling, Operation, and Technologies are continued and further enhanced, as these are indispensable for the effective support of computational sciences in the HPC area. The service provisioning model will be extended from one that supports single projects to one supporting Virtual European Communities. Collaborative activities will be carried out with new European and other international initiatives.
Of strategic importance is the cooperation with the PRACE project which is preparing for the installation of a limited number of leadership-class Tier-0 supercomputers in Europe. The key role and aim will be to deliver a turnkey operational solution for a future persistent European HPC ecosystem, as suggested by ESFRI. The ecosystem will integrate national Tier-1 centres and the new Tier-0 centres.
DEISA: Achievements to build on
In spring 2002 the idea emerged to overcome the fragmentation of supercomputing resources in Europe both in terms of system availability and in the necessary skills for efficient supercomputing support. The establishment of a distributed European supercomputing infrastructure was proposed.
In May 2004 the DEISA project was started as a EU FP6 Integrated Infrastructure Initiative by eight leading European supercomputing centres. In 2006 DEISA was joined by three additional leading centres. Through the joint efforts, DEISA reached production quality soon after to support leading edge capability computing for the European scientific community. DEISA has also contributed to a raising awareness of the need for a persistent European HPC infrastructure as recommended in the ESFRI report 2006.
The DEISA Extreme Computing Initiative (DECI), launched in 2005 with annual calls, has supported challenging European supercomputing projects during the last three years. For the most challenging projects the most most powerful and most appropriate supercomputer architectures available in Europe could be offered. So far scientists from 15 different European countries with collaborators from four other continents have benefited.
In the DEISA2 projects, the DECI is continued, but these single-project oriented activities will be qualitatively extended towards persistent support of Virtual Science Communities. DEISA2 will provide a computational platform for them, offering integration via distributed services and web applications, as well as managing data repositories. Emphasis will be put on collaborations with research infrastructure projects established by the ESFRI, and European HPC and Grid projects. The activity reinforces the relations to other European HPC centres and leading international HPC centres and HPC projects world-wide. For supporting international science communities across existing political boundaries, DEISA2 participates in the evaluation and implementation of standards for interoperation.
Taking care of the operation of the infrastructure and the support of its efficient usage is the task of the three service activities Operations, Technologies and Applications, which are complemented by two Joint Research Activities.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
