Scientific Computing and Numerical Simulations

Solving realistic problems of physics on large cosmological scales under extreme conditions of strong gravity or conversly in the microworld of  subnuclear physics represents an extremely difficult task and demands enormous amout of computational power. The same holds for the processing of large sets of observational data. Computer implementations of numerical methods, statistical data processing and physical simulations have therefore become an important part of modern relativistic astrophysics, subnuclear physics, or the quantum theory of many particles. High computational power along with sophisticated graphics accelaration is also necessary to create multimedial visualisations and simulations destined for the laic public.

Our Institute disposes of software and hardware resources for both standard and paralel computing, programming, and observational data processing. Researchers at the Institute work on developing their own numerical codes able to solve problems of relativistic astrophysics and quantum subnuclear physics.


Our Computer Gear   

  • Blade

The IBM BladeCenter® multiprocessor modular server supports a wide spectrum of the CPU architecture and operating systems which enable the clients to execute the entire load of various types within a single environment. Our system is equipped with three dualprocessor boards LS20 for IBM BladeCenter with AMD Opteron dualcore CPUs. The configuration therefore represents the combination of symmetric multiprocessing within a single processor board and clustering on the whole system. Our Blade server is used for batch-running of compiled numerical codes and supports paralel processing and programming through the MPI interface.

  • Nora & HAL9000

Nora and Hal9000 are twins. The two identical IBM Intellistation A Pro workstations, equipped with AMD Opteron 285 dualcore CPUs, have different utilizations though. Nora is used as a Linux application server and operates some processes running on the Blade server as well as these websites. On the other hand, Hal9000, the twin brother of Nora, runs the 64bit Windows XP x64 and is intended for interactive scientific computing and programming.

  • Personal Laptops and Desktops

The staff members that participate in the Institute's research activities are equipped with powerfull IBM/Lenovo ThinkPad laptops and Thinkcentre desktops.
