Computational grid-cluster

Grid system of the Institute of Applied Physics is a part of the Ukrainian National Grid System and is used for complex calculations by the Institute's staff and researchers from other academician institutions.


IAP cluster is a Beowulf cluster, which consists of 11 client nodes and a server node. Users can utilize 88 cores for calculation as well as a wide range of applications and compilers, which are  MPI and OpenMP - friendly. To control node loading a Torque system is used.

    Server node:
  • 2x Intel® Xeon® CPU 3.2 GHz, 2Gb memory, 3x 250GB HDD
  • Operating system: Scientific Linux 5, core 2.6.18 i686

The node works as an entry point for users and supports the basic services: PBS server, MySQL database, license servers, NFS-server.

    Client nodes:
  • 2x Intel® Xeon® CPU Quad-Core 5320, 4Gb memory, 2x250GB HDD
  • Operating system: Scientific Linux 5, ядро 2.6.18 i686
  • Programming languages: C/C++, Fortran (gcc 4.1.1, Intel Fortran Compiler 11.0), perl 5.8.8, python 2.4.3
  • Special package: Wien2k

An internal grid net is built on the basis of Gigabit Ethernet, external channel – 50Мb/s

The computational cluster  can be used by IAP staff  to solve scientific tasks. The grid cluster is connected with the Ukrainian national grid that allows its utilization by research workers of other NAS organizations. 

Institute's staff carries out studies in the following directions:

  • Studies of non-linear dynamics of charged particles in the probe-forming systems allowing for the initial non-uniform particle distribution in the phase volume and inhomogeneous linear gradient magnetic fields.
  • Simulation of high-frequency ionization and heating of plasma electron component in the presence of the inhomogeneous magnetic field using 3-D codes to solve equations for components of electromagnetic fields and to characterize confined plasma (density, electron and ion temperature, etc.).
  • Simulation of extraction of ion beam from the helicon plasma and optimization of the phase characteristics of extracted ion beam.
  • Simulation of a defect formation in structural materials of nuclear  engineering as a result of irradiation, and further formation of hierarchical defect structures and their evolution to estiamte degradation of physical-chemical properties of materials and characteristic time of the processes.
  • Simulation of the particle beam passing through the amorphous and crystal materials allowing for the cascades of atomic displacements, excitation and relaxation of the electron subsystem, and surface and orientational effects.
