PRACE Investigated Application Requirements

14.10.2008
PRACE, the Partnership for Advanced Computing in Europe, investigated application requirements for European Petaflop systems. The investigation work consists of an analysis of the behaviour of a set of applications on current hardware platforms, and a survey of key users.

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.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
