Simulation Laboratory for Elementary- and Astro- Particle Physics

In the particle- and astro- physics the computations using distributed systems, as well simulations on supercomputers with data intensive communications are common and inevitable.
SimLab Astro und Elementar- Teilchen

Modern scientific problems in the Elementary- and Astro- particle physics are only partially solvable without development of special software for computer aided simulations with use of high performance computing (HPC) systems. Moreover, trivial use of computing resources is not yet relevant, as of increasing complexity of scientific problems resulting to needs of running simple computer for a years to simulate and analyse the results. Simulation Laboratory for Eelementary- and Astro- Particle (SimLab EA Particle) at SCC of KIT is established to provide high level support for research groups from international and national institutions working in field of particle- and astro-physics to make the complex theoretical and experimental problems solvable with use world best supercomputing resources, e.g. PRACE, EGI). SimLab EA Particle acting as a tie between development of simulation software and optimal implementation of it on supercomputing systems

 

Goals and competences

Support scientific groups with concept „S.P.O.R.A.D.I.C. services for simulations“ (Standardisation, Parallelising, Optimization, Release, Adaptation, Data Intensive Computing)

  • Modernisation of old simulation codes, making code object oriented, standardisation of I/O dataformats, usage of modern mathematical and scientific libraries - Standardisation
  • Implementation of trivial and advanced algorithms for parallel runs of code, speed-up to solve complex problems in acceptable time scale on multi and many core systems- Parallelising
  • Performance-analysis, acceleration of simulations reducing usage of resources - Optimization
  • Simulation code as a software: licensing, documentation, implementing versioning system and providing repository for storage of source code and simulation results - Release
  • Porting of codes and access to high performance super- and distributed computing systems, developing algorithms for use of code at HPC, grid and cloud resources - Adaptation
  • Data Intensive Computing
    • Storing and managing outputs of simulation and experimental data
    • Visualisation of results, data intensive statistical analysis
    • Development of user friendly workflow and bookkeeping interfaces, resource orchestration systems

Current activities - cooperations

Air shower

SimLab EA Particle cooperates with research centre of KIT for elementary- and astro- particle physics (KCETA) and newly established Karlsruhe School of Elementary Particle and Astroparticle Physics (KSETA). In particular, within the cooperation with institute for nuclear physics we perform simulations for cosmic rays, electromagnetic and radio emission and neutrino detections with use of HPC systems.

With a group from University of Westminster, a partners in EDGI project, the codes for parallel runnings of cosmic ray simulations on BOINC driven computing-infrastructures is developed. Here also some pupils from Bismark-Gymnasium are involved, who learns as well supports in building the volunteer computing system, in framework of project Simulierte Welten

m31 Galaxy

In cooperation with research institute for particle und nuclear physics of Hungarian akademy of science, N. Kopernikus Astronomical Center and Mathematical Institute of Polnish Academy of Science, we are working in field of seacrh for grawitational waves in VIRGO collaboration

Evolution scenarios for compact astrophysical objects are studied in cooperation with University Wroclaw in Poland, Yerevan State University in Armenia and Joint Institute for Nuclear Research in Dubna, Russland

For a scientific group from GSI Darmstadt and University Wroclaw we are parallelising simulation code for parameteric study of nuclei clusters in matter at high densidy and temperature. These are phänomenological model for modeling heavy ion collisions and low energy nuclear processes like to find in supernovae explosions.

SimLab EA Particle supporting research group from Universität Potsdam/DESY Zeuthen to study magnetic fields in universe as a potential particle accelerators, e.g. for particle acceleration model on a shock wave fronts of supernovae explosionen. Here the optimisation of simulations codes is provided to enable efficient use of high-end supercomputing resources

  • CORSIKA code for simulationen von Cosmic Rays: parallelised, optimized and adapted onto HPC and distributed computing systems of SCC and EDGI
  • Code for solving Einstein-equations in approximation for spherical symmetry (own development): standardised, optimised, adapted to up-to-date computing systems
  • Software for analysing and searching the srouces of GW in data of VIRGO collaboration: paralelising, adaptation of software onto HPC systemes
  • Particle-in-Cell Simulationscode THiSMPI (Two-and-a-Half-Dimensional Stanford with Message Passing Interface): performance analyses, scalability tests
  • Advanced liquid drop model - Weizsäcker formel for finit temperatures : parallelisiing, optimising, adapting into HPC systemes
