PRACE investigated the applications and other software that will run on future European Petaflop systems. The application codes analysed are those selected earlier by PRACE as representative of the likely load on European Petaflop/s systems and which are candidates for inclusion in a benchmark suite to help select such systems.
The applications analysed are covering molecular dynamics and quantum chemistry (NAMD, CPMD, CP2K, GROMACS, GPAW, VASP), atomic physics (HELIUM), cosmology (GADGET), computational fluid dynamics (CODE_SATURNE, N3D, ALYA), plasma physics (TORB, PEPC), particle physics (QCD) and earth system modeling (NEMO, ECHAM5).
Each of the applications was run on one of the classes of architectures identified by PRACE as suitable prototypes for future Petascale systems. The appropriate data sets for each application were selected and profiling data on production-scale runs was collected so that the requirements of each application could be identified.
In addition, PRACE complemented this data by the results of a survey of many of the major HPC (High Performance Computing) users in Europe. A survey was sent to the major HPC users in most PRACE countries asking for their input on future applications requirements. This survey included questions about the user, usage patterns, HPC infrastructure, upcoming algorithms and general comments about future Petascale systems. Almost 70 responses were received and analysed by PRACE.
PRACE Work Package 6, which has been leading this investigation work has so far investigated the usage of most major HPC systems across Europe, the key applications and algorithms used, the performance of these applications on key architectures and the views of major users on emerging applications requirements. This provides a full picture of the requirements of current applications and identifies how these would translate to future Petaflop systems.
This work is essential for later tasks in PRACE which will involve optimising and petascaling these applications and packaging them into a benchmark suite to be used in future Petaflop procurements.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
